What is titanium diboride

Among many compounds, metal borides have better high-temperature properties than metal carbides. For example, diboride (TiB2) cermet products are more suitable for use under high-temperature and highly corrosive working conditions than titanium carbide (TiC) and tungsten carbide (WC) cermet products. Titanium diboride powder is gray (or grayish black), ranking sixth among the currently known top ten materials with the highest melting point in the world (see Table 1 for the melting point ranking table). The oxidation resistance temperature in the air can reach 1100 ℃. As a new ceramic material, it has excellent physical and chemical properties, high hardness and melting point, excellent chemical stability, electrical conductivity, and mechanical properties at high temperatures. Titanium diboride powder is gray or grayish black with a hexagonal (AlB2) crystal structure. Its melting point is 2980 ℃, with high hardness. The oxidation resistance temperature of titanium diboride in the air can reach 1000 ℃, and it is stable in HCl and HF acids. Titanium diboride is mainly used to prepare composite ceramic products. Due to its resistance to molten metal corrosion, it can be used to manufacture molten metal crucibles and electrolytic cell electrodes. Titanium boride (TiB2) is the most stable compound of boron and titanium, with a C32-type structure. It is bound in the form of its valence bond and belongs to a hexagonal system of quasi-metallic compounds. The structural parameters of its complete crystal are a=0.3028 nm and C=0.3228 nm. The crystal structure's boron and titanium atomic surfaces alternately form a two-dimensional network structure. B and the other 3 B are covalently bonded, and the remaining electron forms a large π bond. This layered structure of boron atoms is similar to graphite, and the outer electrons of Ti determine that TiB2 has good electrical conductivity and metallic luster. In contrast, the Ti-B bond between the boron and titanium atomic surfaces determines this material's high hardness and brittleness.  If you are looking for high quality, high purity and cost-effective titanium diboride, or if you require the latest price of titanium diboride, please feel free to email contact mis-asia.
