Boron Carbide

Lightest weight technical ceramic material as well as high hardness. Fully dense boron carbide is produced by hot pressing. Other characterized as follows: erosion resistance, high modulus, and neutron absorber. Boron Carbide used in semiconductor components, sputtering targets, wear components, boron carbide tiles, armor and boron carbide B4C nuclear 

Glass Ceramics

Used for glass ceramic machining. An excellent insulator at high voltages, various frequencies, and high temperatures up to 800oC to 1000oC. Will not outgas in vacuum environments when baked out properly.  

Silicon Carbide

This material has a high strength, low density, oxidation resistance (reaction bonded) characteristics. Quality thermal shock resistance, high hardness, wear resistance, low thermal expansion and electrical conductivity.  

Silcon Nitride

High Thermal Conductivity – Electrical Insulator – Corrosion Resistant. Totally dense material having a scope of compositions that can be manufactured cost effectively including complex forms and shapes.   

Zirconia 

ZIrconia ceramics have high mechanical strength and toughness. Excellent surface smoothness.

Generally ceramics can be characterized as very hard, enormous wear resistant, high temperature-stable and also resistant to most of popular acids and bases. Most ceramic materials offer excellent electrical insulating properties combined with a poor thermal conductivity. These characteristics allow an operation in various application areas and branches of industry.
