High Temperature 26mm Alumina Ceramic Hot Surface Igniter with Flange Cap
Installation prohibition
Please design your system in order that the heating element of the heater never enters directly in contact with solid fuel or ashes or metal protective tube. If the heating element enters in contact with solid fuel, ashes or metal protective it could damage the heating element. Longer protective tube should be consider to avoid this situation.
Please make sure to let an interspace of minimum 3mm around the ceramic heating element and the tube.

INNOVACERA was incorporated in 2012 and since then producing ignition components for gas and biomass sector. The company complies with ISO 9001 and ISO14001.
Innovacera metallizes precision ceramic for military, medical, and aerospace applications. Our metallization creates a strong and robust bond to many different ceramic bodies and has nearly universal applicability for ceramic to metal brazing.
Our ceramic metallization process uses proprietary thick film molybdenum/manganese and molybdenum/manganese/tungsten paints as the base layer on a ceramic substrate. To prevent oxidation and to improve wettability after the metallization paint is sintered into the ceramic at high temperature, it is plated using either electroless or electrolytic plating or nickel oxide paint.

Authors of an new Early View story on the website of the Journal of the American Ceramic Society report about a solution they have found to some of the problem of shrinkage and deformation that occurs during sintering of large and complex parts composed of one type of bioactive glass.
The investigators, who are from the Department of Materials Science and Engineering, University of Erlangen-Nuremberg (Germany) and the BAM Federal Institute for Materials Research and Testing (Berlin), have been looking at how to improve the performance and production of 3D-printed “13-93″ bioactive glass and they say the addition of hydroxyapatite powder, creating a glass–ceramic composite for 3D printing, creates a finished product that retains more of the critical shape and dimensions during sintering than pure powders of the glass.
13-93, a silicate-based glass, isn’t new and several groups of researchers (such as Rahaman et al.) have generally documented that 13-93 is a good candidate material for non-load bearing uses in joint replacement and tissue engineering. The active interest in bioactive glasses, such as 13-93, is in large part due to the apparent ability of the material to accelerate the body’s natural healing process.
Different groups had experimented with using different processes to create green body structures using 13-93 powders and filaments, including fairly precise 3D fabrication and finishing methods, such as selective laser sintering. However, generally speaking, the larger and more complex the green body is, the more problematic sintering becomes. The authors of the JACerS paper report these types of parts “may deform significantly as a result of gravity, surface tension, intrinsic strain or temperature and density gradients. This complicates congruent or net-shape processing.”
The attractiveness of 3D processing is the promise of high-quality and easily reproducible shapes, pore size and distribution, etc.
The payoff in the German group’s work is that they found that a 13-93/HAp powder mix using 40 wt% of crystalline material provided the best combination of geometric stability and viscous sintering. They tested this formulation using the complex cellular cubic structure pictured above, and they were quite happy with the results. They note
“In this way, an overall axial shrinkage of about 20.5 ± 0.5% was obtained in all three dimensions. The diameter of cells was reproduced with an accuracy of 15 ± 5%, whereby the deviation is most probably related to surface effects induced by the printing process and manual powder removal. The ratio between individual cell diameters—the fingerprint of the specific structure—was reproduced with an accuracy of about 2%. … these data demonstrate very good reproduction of the 3D-printed part after sintering.”
Also, the addition of the HAp powder seems to not increase the propensity for crystallization of the bioglass, another problem that may change the properties that made the material desirable in the first place.
The authors suggest that other glass–ceramic composite candidates should be suitable for similar production methods.

Alumina ceramic is a kind of ceramic material with a-al2o3 as the main crystal phase, because of its own high melting point, high hardness, heat resistance, corrosion resistance, and electrical insulation characteristics, it can be used in more stringent conditions. Alumina ceramics, with low price and mature production process, is one of the largest and most widely used ceramic materials, mainly used in the field of cutting tools, wear-resistant parts, and bioceramics. In addition, it is also widely used in energy, aerospace, chemical electronics, and other aspects. Especially 95% alumina and 99% aluminas, whether in structural ceramics or electronic ceramics are one of the most widely used ceramic materials.
In the production process of alumina ceramic parts, such as alumina ceramic tubes, alumina plates, and alumina rods there are often black, brown, and pink spots on the surface of the ceramic part, as well as on the inside. This spot is one of the main reasons for the unqualified alumina ceramic products.
The main impurities of black and brown spots are Fe, and the main impurities of pink spots are Fe, Cr, and Ni. By analyzing the composition of the spots and tracing the production process, it can be preliminary determined that the black and brown spots are mainly caused by mixing mechanical iron particles in advanced ceramic production. And pink spots from the composition analysis can be judged to be caused by stainless steel material fine particles.
Now we know the reason why alumina ceramic components have spots, how do we prevent and solve it?
Raw materials: choose raw materials with good quality and low iron content as far as possible, and remove iron by magnetic separation when necessary.
Grinding: pay attention to observing whether the ball mill lining brick falls off and timely repair.
Granulation: slurry conveying with magnetic separation to remove iron, hot blast furnace, and hot air filtration to avoid hot air system rust into the material. The granulated powder is magnetically separated to remove iron before final product packaging.
Piping: All piping should be lined with polyurethane whenever possible.
