Ceramic Boron Nitride Setters For Sintering Nitride Ceramics

BN setters

Due to Boron Nitride’s high purity, non-adhesive and long working life, it’s a good choice used for sintering Aluminum Nitride and Silicon Nitride substrates. And it won’t make pollution for the sintering process.

Hexagonal Boron Nitride has a low expansion coefficient and high thermal conductivity, so it has excellent thermal shock resistance, and it will not be damaged even after hundreds of times of cycle use at 2000°C. The expansion coefficient of BN is equivalent to that of quartz, but the thermal conductivity is 10 times that of quartz.

Features of Boron Nitride:

  • High purity with 99.7%
  • Quality stable in mass production
  • No deformation in high temperature
  • Max working temperature is over 2100°C
  • Resist high heat shock

All the features make Boron Nitride a very good material for the sintering field. Our Boron Nitride is an alternative for Denka NB-1000.

The advantages for choosing us:

  • Competitive price
  • Short delivery time (20-35 days)
  • Stable quality
  • Do adjustments very quickly due to customers’ feedback on quality.
  • The max dimension we can make: 500×500 mm

What Are The Advantages of MgO-ZrO2 Ceramic?

MgO ring

Magnesium oxide Zirconia ceramics have high oxygen ion conductivity, high strength and toughness, and good thermal shock resistance. It is a promising high-temperature functional and structural ceramic material. Magnesium oxide is used as a stabilizer. The cubic phase material is packed into tiny tetragonal deposits and thus has a very high transformation toughness. The fracture toughness of magnesium oxide Zirconia is high.

It has excellent mechanical properties, including high strength, fracture toughness, wear resistance, low thermal conductivity, and good thermal shock resistance. Because of its resistance to wear and corrosion, it is mainly used in valves, pumps, and gaskets, and is also used in chemical processing and petrochemical industries.

Alumina ceramic substrates for the automotive industry

Alumina ceramic substrates for automautive industry

Alumina ceramics is a ceramic material with a-Al2O3 as the main crystalline phase. Because of its high melting point, high hardness, heat resistance, corrosion resistance, and electrical insulation characteristics, it can be used under harsher conditions. Alumina ceramics have competitive prices and mature production technology. It is currently one of the ceramic materials with the largest output and the widest application range. It is mainly used in the fields of cutting tools, wear-resistant parts, and bio-ceramics. In addition, it is also widely used in energy, aerospace, chemical, chemical, and electronic fields. In particular, 95% and 99% alumina ceramic components, whether in structural ceramics or electronic ceramics, are some of the most widely used and most used ceramic materials.

Such Alumina ceramic substrates now are widely used in the automotive industry, especially the large ceramic substrate. Innovacera are specializing in alumina ceramic substrates, the max size of AL2O3 ceramic substrates Innovacera made is 380*200*1 mm (0.8 mm and 0.635 mm thickness are also available). The substrates are part of a specific brazing process, used as spacers during thermal treatment.

PBN-PG Composite Heating Elements

PBN-PG-Heater-Element PBN-PG-Heater-Element

High purity and high-performance pyrolytic boron nitride are used as the substrate for the PBN heating element. Pyrolytic graphite (PG) is placed on the surface of PBN plates by the CVD method as a conductor and heater.

As both PG and PBN are extremely pure and very stable in a vacuum or inert atmosphere, the PBN-PG heating element could be very durable and keep the chamber clean. It could be heated to 1600°C in a very short time without the emission of any gas component. These heating elements are ideal products for the semiconductor industry and applications that require high temperature, high vacuum, and high purity.
