What is the property of hafnium boride?
Hafnium boride is a gray crystal with metallic luster. Its melting point is 3250 degrees Celsius, it has the characteristics of high conductivity and stable chemical properties. At room temperature, hafnium boride hardly reacts with all chemical reagents (except HF). Hafnium boride is prepared by mixing hafnium dioxide, boron carbide or boron oxide, and carbon powder by heating.
Hafnium boride powder is prepared by a variable current laser ion beam gas phase method. It is a new ceramic material with high melting point, high thermal conductivity, oxidation resistance and other high-temperature comprehensive properties. It is mainly used in high-temperature ceramics, high-speed aircraft nose cones, and aviation and aerospace and other fields.
What is the application of hafnium boride?
With the development of material technology, the application fields of hafnium diboride ceramics and composite materials are becoming more and more extensive. Hafnium diboride is difficult to sinter. In order to improve the sintering performance, it is necessary to obtain ultrafine powder. Although nano-powder has superior performance, its cost is high, and it is difficult to disperse during raw material processing, and the process is difficult. Therefore, the development of sub-micron hafnium diboride powder has been paid more and more attention.
1. Hafnium boride is used as wear-resistant coating; crucible lining and corrosion-resistant chemical equipment; anti-oxidation composite materials; refractory materials, where the corrosion of molten metal is resistant;
2. Hafnium boride is used as thermal enhancement additives; high-temperature resistance; high-temperature, corrosion-resistant and oxidation-resistant special coatings;
3. Hafnium boride is mainly used as a material for the production of composite ceramics; can be used as a neutron absorber;
4. Hafnium boride is used in high-temperature ceramics, high-speed aircraft nose cones and aviation, aerospace and other fields.
