What is Zirconium Diboride Powder?

What is it?

Zirconium Diboride


Zirconium Diboride (ZrB2), a type of high covalent ceramic material with hexagonal crystal structures, is one example. It is an ultrahigh-temperature ceramic (UHTC), having a melting temperature of 3246degC. It is a very low density at 6.09 g/cm3 (though it may have a higher density due to hafnium inclusions) and has excellent high-temperature resistance, making it suitable for high-temperature aerospace uses such as hypersonic flight and rocket propulsion systems. It is an uncommon ceramic with high thermal conductivity and electrical conductivity.

The key features of

Zirconium Diboride Powder

Zirconium boride is a gray-colored crystal found in nature. Three components of zirconium boreide are zirconium biboride (zirconium diboride), zirconium tribromide (zirconium tribromide) and zirconium bromide (zirconium boride). Only zirconium tribromide is stable across a wide temperature range. The industrial production uses mainly zirconium boride. Zirconium dioxide is a hexagonal or gray crystal, powder, or crystal with a melting temperature of 3040. Zirconium dioxide is highly resistant to high temperature. It also has high strength at high and normal temperatures. High resistance to high temperatures, good shock resistance and low resistance to oxidation. With metallic luster. It is metallic. The resistance to it is slightly lower than zirconium. Stabilizes at all temperatures after heating. It can be sintered at lower temperatures, despite having a high melting point.

The applications

Zirconium Diboride Powder


Zirconium Diboride is a strategic material that has high hardness and high thermal conductivity. It also has good oxidation resistance, corrosion resistance, and oxidation resistance. It is used mostly in the thermal protection system, high-temperature electrodes, heat trap pipes and reentry planes.

2. Zirconium Diboride can be used in aerospace as a high temperature resistant material. It is particularly well-suited for use on the surface of a rolling bearing ball.

3. Zirconium boride is a great candidate material to make thin-film electronic components for sensors, actuators, and microsystems operating at high temperatures. This is due to its metal-like conductivity as well as melting temperature of 325°C.

4. Zirconium boride is used in special ceramics refractories industries, nuclear industry and military industry. Zirconium boride can also be used to coat rolling balls or smooth solid materials. Composites made of carbon fiber reinforced zirconium dimoride composite are high in density. However, the composites made from silicon carbide fiber reinforced zirconium dimoride composite are brittle.
