CAS 12045-64-6 ZrB2 Powder Zirconium Boride

Overview of Zirconium Boride  

Zirconium boride powder is a chemical compound with the molecular formula ZrB₂. It consists of gray, hard crystals and is primarily composed of three components: zirconium monoboride, zirconium diboride, and zirconium triboride. Among these, only zirconium diboride is stable over a wide temperature range, making it the focus of industrial production.
Zirconium diboride is a hexagonal crystal that appears as a gray powder. It has a relative density of 5.8 and a melting point of 3,040°C. It exhibits good thermal shock resistance, low resistance, and anti-oxidation properties at high temperatures. The melting point is approximately 3000°C, and it has a metallic luster. It has high-temperature resistance and maintains strength at both room and high temperatures. It exhibits good thermal shock resistance, low resistance, and anti-oxidation properties at high temperatures. The melting point is approximately 3000°C, and it has a metallic luster. With a lower density of approximately 6.09 g/cm³ (note that the measured density may be higher due to impurities), this material exhibits excellent high-temperature strength. It is well-suited for high-temperature aerospace applications, such as hypersonic flight and rocket propulsion systems. This ceramic has specific applications in furnace components, high-temperature electrodes, rocket engines, and thermal protection structures for spacecraft, where it can withstand temperatures exceeding 1800°C.
Furthermore, it is distinguished by its relatively high thermal and electrical conductivity, making it suitable for heavy-wear applications. Zirconium diboride (ZrB2) shares the same characteristics and structure as titanium diboride. It is known for its exceptional fire resistance, high thermal conductivity (greater than 50 W/m/K), inertness to molten metals, good thermal shock resistance, and high electrical conductivity (approximately 105 S/cm). Additionally, ZrB2 can be processed using Electric Discharge Machining (EDM) basic ceramic molding. ZrB2 parts are typically produced through hot pressing, which involves applying pressure to heated powder, followed by machining to achieve the desired shape. The covalent nature of the material and the presence of surface oxides hinder the sintering of ZrB2. The presence of surface oxides will increase the coarsening of crystal grains before densification during the sintering process. Pressureless sintering of ZrB2 is possible. Sintering additives such as boron carbide and carbon will react with surface oxides, thereby increasing the driving force for sintering. However, the mechanical properties will be reduced compared to hot-pressed ZrB2. If you would like to purchase Zirconium Diboride ZrB2 Powder in bulk, please send an inquiry for the latest price.

Application of Zirconium Boride

ZrB₂, or zirconium boride, is a high-performance ceramic used in aerospace for thermal protection, cutting tools for hardness and wear resistance, the nuclear industry for radiation tolerance, and electronics for heat dissipation. Its high melting point, hardness, and thermal conductivity make it suitable for extreme conditions. ZrB₂ enhances tool life, reactor safety, and device reliability.

Production Method of Zirconium Boride 

The production method of zirconium boride primarily involves four approaches:

1. Direct reaction between zirconium metal and boron.
2. The carbide boron method, which involves reacting zirconium oxide, boron carbide, carbon, and boron oxide under high temperature.
3. Carbon reduction method.
4. Vapor deposition method.
