Ultra-high Temperature Ceramic Matrix Composite Material - Zirconium Diboride
Zirconium diboride (ZrB2) has high melting point, high hardness, high stability and good electrical conductivity, thermal conductivity, oxidation resistance and chemical resistance, which makes composite ceramics made of zirconium diboride as raw material excellent comprehensive performance. So zirconium diboride is very suitable for ultra-high temperature ablation resistant materials used in supersonic spacecraft and missile casings.
The company mainly produces 1.0-3.0um (D10=1.0±0.2um, D50=1.5-1.8um, D90=3.0±0.2um, 1.0-3.0um≥80%) zirconium diboride powder materials for special purposes. High purity, concentrated particle size distribution, good activity, good sintering quality and other characteristics, mainly used in the field of aerospace ultra-high temperature structural ceramics
The advantage of special zirconium diboride as a filler material for resin matrix composites is that the active time is as long as 300-500 seconds.
Reference application: An aerospace material and technology research institute uses our company's 1.0-3.0um zirconium diboride powder material to produce ZrB2/SiC carbon fiber reinforced composite ceramic radome parts, the material density quotient reaches 98% TD, and the bending strength and fracture toughness reaches 600MPa and 6.95MPa·m1/2, and has good oxidation resistance and mechanical properties.
