Titanium Diboride Powder
Titanium Diboride Powder
Titanium Diboride (Tib2) is produced by Momentive Performance Materials (Formerly GE Advanced Materials) using a continuous chemical process that
controls stoichiometry and particle size to create high purity powder. The shapes of the processed crystals are flat, hexagonal platelets.
When solidified into shapes, the resultant ceramic is electrically conductive, a property very rare among ceramic materials. This makes it valuable in
electrical applications and also enables it to be formed into complex shapes using electrical discharge machining (EDM). TiB2 combines superior
hardness and corrosion resistance with a high
melting point (>2900°C) and good oxidation resistance to 1000°C.
Key Properties
Extreme Hardness
Nearly as hard as diamond when sintered, TiB2 is tough enough to be used as military armor and improves the fracture toughness
of ceramic cutting tools and other components.
Electrical/Thermal Conductivity
As an excellent conductor of both electricity and heat, TiB2 is valuable in electronic and specialty applications. TiB2
enhances thermal conductivity when used as a filler in polymeric matrices.
Chemical Resistance
Titanium Diboride will not react with molten, nonferrous metals including Cu, Zn and Al. TiB2 is used as crucibles, vacuum
metallization components and electrodes for processing these materials.
- Electrically conductive composites such as aluminum evaporation boats
- Complex, sinterable TiB2 shapes
- Additives for producing specialty ceramic composite materials
- Refractory material and antioxidant additive that is nonreactive to most molten nonferrous metals and alloys
- Thermal management materials
