The resistance is slightly lower than that of metal zirconium. Stable in a wide temperature range after heating. Although the melting point is high, it can be sintered at lower temperatures. It is prepared by mixing metal zirconium with boron carbide and boron nitride and heating to 2000℃ in argon flow.

Zirconium Diboride ZrB2 Powder Overview

Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. It is an ultra-high temperature ceramic (UHTC) with a melting point of 3246°C. Its relatively low density of about 6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high temperature strength make it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems. It is an unusual ceramic with high thermal and electrical conductivity, with the same properties as titanium diboride and hafnium diboride, with the same structure.

Zirconium diboride is resistant to high temperature and has high strength at room temperature and high temperature. Good shock resistance, low resistance, oxidation resistance at high temperature. Has metallic luster. It has metallic properties. The resistance is slightly lower than that of zirconium. Stable over a wide temperature range after heating. Although it has a high melting point, it can be sintered at lower temperatures.

Application of zirconium diboride ZrB2 powder

With the rapid development of science and technology, long-range missiles, rockets, space shuttles, spaceships, supersonic aircraft and other aircraft are developing in the direction of higher speed, greater thrust, higher altitude and safer. higher requirement. Various properties of the aircraft. Due to the strong friction between the aircraft and the atmosphere, a lot of heat is generated. The first thing to improve is the high temperature resistance of aircraft materials, including refractory metals, carbides, carbon-carbon materials and borides. Zirconium diboride ceramics have the advantages of high melting point, high hardness, high strength, high corrosion resistance, high chemical stability and high electrical conductivity.

Zirconium diboride is a strategic material with high hardness, high thermal conductivity, good oxidation and corrosion resistance. Mainly used for thermal protection systems, high temperature electrodes and heat trap tubes of re-entry vehicles.

Zirconium diboride can also be used as high temperature resistant materials for aerospace, wear-resistant and smooth solid materials, cutting tools, thermocouple protection tubes for temperature differences and electrode materials for electrolytic molten compounds. Particularly suitable for the surface of rolling bearing balls.

Zirconium diboride is a good candidate for thin film electronics for sensors, actuators and microsystems operating in high temperature environments due to its metal-like conductivity and melting temperature of 3245°C.
