Ultra-high temperature ceramic matrix composites - zirconium

Zirconium diboride, the metal structure compound of hexagonal system, is a kind of senior engineering material broadly used in various fields. The composite ceramic made of zirconium diboride is featured with excellent performance due to high melting-point (3040℃), high hardness, high stability as well as good electrical conductivity, thermal conductivity, inoxidizability and resistance to chemical corrosion. Moreover, Zirconium diboride, as the ultra-high temperature zero ablative material, is very suitable for supersonic aerospace craft and missile shell. 

Our company mainly produces 1.0-3.0um (＜1.0um, ≯5%; ＞3.0um, ≯5%), 150 nm and 45 nm zirconium diboride powder materials，ZrB2 compound by our company based on new techniques is featured with high purity, even size distribution, large specific area, high surface activity and low apparent density, etc.

Example: Certain aerospace materials and technology research institute uses zirconium diboride powder material with 1.0-30um of our company to produce hood parts of ZrB2/SiC carbon fiber reinforced composite ceramics antenna, of which the material density is up to 98%TD, bending resistance is up to 600MPa, and fracture toughness is up to 600MPa and 6.95MPa•m1/2, with good oxidation resistance and mechanical properties.
