The Application of Alumina and SiC Porous Ceramics

Application:
Semiconductor wafer processing, laser numerical control processing, PCB, flexible screen, precision grinder, air floating platform, air bearing, optical components.
1) The smaller the pore size, the greater the resistance and the greater the degree of vacuum required, but the greater the suction power obtained.
2) The maximum use temperature of alumina/silicon carbide microporous ceramics is about 1000 ° C, and the maximum use temperature is also related to size and shape. Still, if glue is stuck, it can only be lower than 100 ° C.
3) Microporous ceramics generally do not mention the roughness problem, because there are micropores, but the surface smoothness is similar to Ra0.8 of dense ceramics.
4) Low thermal conductivity. Only dense materials will have high thermal conductivity.
5) Microporous ceramics cannot be used in a humid environment or come into contact with conductive liquids. Otherwise, they will not be insulated.

Ceramic Heating Element Introduction

Ceramic heating element is a resistive piece of ceramic, often treated with a metallic coating. The ceramic heating element creates heat based on resistance to electrical flow through the ceramic element. This is done to provide heat to a room or other area via convection or forced air.
Ceramic Rod Heaters are preferable in many ways to wire heating elements or other bare metal elements. They typically last longer and provide more even heat than a wire heating element. Wire heating elements will eventually burn up and cease to produce heat, and may potentially cause a fire if they come into contact with flammable materials.

Ceramic Heating Element

One benefit of a ceramic heating element is that it may more evenly distribute the heat during operation. This allows for more of the heat created by the resistance of the electricity to be distributed to the room or area being heated rather than being lost to waste. In addition, ceramic elements do not get as hot as metal wire filament elements, so they are less likely to cause burns if inadvertently contacted. They are also less likely to cause accidental fires from contact with flammable materials in their environments.
Another benefit of ceramic heating elements is that they are typically more durable than traditional wire filament heating elements, which generally become brittle after a number of heating cycles and which may crack or break and cause the heater to not work. A ceramic heating element can withstand tens of thousands of heating and cooling cycles without the potential for cracking or breaking unless it is subjected to extreme stress such as a drop or a direct hit from a foreign object. For this reason, ceramic heaters are often used in homes where they will not receive a lot of maintenance or gentle care.
One final benefit of ceramic heating elements is their cost. They are easy to manufacture and distribute, and because they are a better method than traditional heating elements, they have become prevalent in low-cost heaters sold on the mass market for public or private consumption. Ceramic heating elements can provide better quality and durability for the cost, as well as better, more consistent and even heating across the board. Due to these features, it has become common to find a ceramic heating element used in various heating systems.

Why Zirconia Ceramic Plunger Is Better Than Metal Plunger?

If you are looking for a ceramic plunger, you may think of a zirconia ceramic plunger as it is more durable. Correct. Today we are going to introduce this kind of zirconia plunger.

The contact surface with the medium and the working surface is all zirconia ceramics, the plunger rod and the metal handle are mechanically connected, and the adhesive is filled between the ceramic piece and the metal handle to prevent the thread from loosening.

Compared with the existing ceramic piston plunger, it has the characteristics of anti-shedding, reliable connection, and high strength; at the same time, the service life of the zirconia ceramic plunger is 10 times longer than that of the metal plunger, which can also improve the life of the sealing packing, and has extremely high wear resistance. damage, corrosion resistance, and impact resistance.

It is widely used in plunger pumps used in medical, petroleum, chemical, food machinery, and other industries.

Ceramic Igniter Use For Pellet Burner

One special application area for Innovacera high-temperature ceramic igniter is in heating systems that use solid fuels such as wood pellets as an energy source. The challenge here is to ignite the biomass in a very short time while retaining very low emission values. This can be perfectly achieved by Innovacera’s hot surface ceramic igniter.

Ceramic hot surface igniter for pellet burners need only approx. 1/10 of the energy of that needed by hot air fans and ignition blowers. Their ignition capacity lies between 120 and 200 Watt. Depending on the positioning of the ignition element in the boiler, the ignition time of approx. 60 seconds is extremely short. This also means minimal emissions!

Igniting wood chips, firewood, coal bricks or other biomass (such as corn, etc.) is possible.

The Difference Between HTCC and LTCC

What is HTCC? It means high-temperature co-fired ceramics which is using alumina, AlN and other ceramic material to be sintering with conductor materials (Mo, W, Mo, Mn) under high temperature of 1600°C. This is first designed by RCA company by the end of the 1950s. Due to the high temperature, it can not use low melting point metal materials like gold, silver and copper, but Mo, W, Mo, Mn.

This material is low conductivity so it will lead to signal delay. So it is not suitable to make high speed or high frequency micro-assembled electric subgrade board. But the advantages of the HTCC are High structural strength, high thermal conductivity, good chemical stability, high wiring density. It has a wide application prospect in high power micro-assembly circuit.

How about LTCC? It has a lower sintering temperature lower than 900°C, using AU, Ag, Cu high conductivity low melting point metal materials could be sintering by air. It is widely used for Rf, microwave and millimetre wave devices.

So when you choosing the ceramic material, please pay attention to what application you need so that you will know if choosing a high temperature or low-temperature ceramic. By the way, our ceramic heater belongs to HTCC.

Ceramic Reflector For Cynosure Laser

Innovacera ceramic reflectors work particularly well in Ruby and Nd: YAG laser pumping chambers and can be a highly cost-effective alternative to metal-coated reflectors. They are also extensively used as reflectors in housings for high-intensity lamps.

ceramic reflector is used for Lamp-pumped Solid-state Lasers

Ceramic reflectors can be glazed both inside the cavity and the out surface using a highly reflective glaze that seals the ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and efficiencies. Glaze can also act as a filter and our yellow glazed reflectors have been used successfully in certain applications. The visible yellow color is complementary to the spectral colors violet and indigo and effectively absorbs these wavelengths up to around 450 nm.

MCH Cereamic Heater Used For Soldering Iron

A soldering iron is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by the combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons, less commonly used today than in the past, were simply a large copper bit on a handle, heated in a flame.

Solder melts at approximately 185 °C (365 °F). Soldering irons are designed to reach a temperature range of 200 to 480 °C (392 to 896 °F).

Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods. Large irons may be used for soldering joints in sheet metal objects. Less common uses include pyrography (burning designs into the wood) and plastic welding (as an alternative to ultrasonic welding).

The advantage of using an MCH ceramic heater in soldering iron are long service time, fast heating rate, energy-efficient and eco-friendly.

And the features are as below:
1. High resistivity
2. Moderate strength
3. Excellent electrical properties
4. Poor heat conductivity (Thermal insulator).
5. Good resistance to thermal shock.
6. Low coefficient of thermal expansion
7. Good mechanical stability.

Our quality inspections rules for the heater are below:
