What is titanium diboride? Titanium diboride powder is gray or gray-black and has a hexagonal (AlB2) crystal structure. Titanium diboride is mainly used to prepare composite ceramic products. Because it can resist molten metal corrosion, it can be used to manufacture molten metal crucibles and electrolytic cell electrodes. Grey or gray-black powder has a hexagonal crystal structure. The melting point is 2900 ℃. The hardness (HV) is 34GPaI, and the density is 4.52. It is wear-resistant, acid and alkali resistant, with strong conductivity and thermal conductivity and a low coefficient of thermal expansion; it has excellent chemical stability and heat resistance. The oxidation resistance temperature of titanium diboride in the air can reach 1000 ℃, and it is stable in HC1 and HF acid.
Uses of titanium diboride Titanium diboride and its composite materials have broad application prospects. Titanium diboride can form composite materials with TiC, TiN, SiC, and other materials. It is used for drawing dies, extrusion dies, sandblasting nozzles, sealing elements, cutting tools, armor protection, and other materials. It is an ideal material for high-temperature-resistant parts and functional devices. As a cathode material for aluminum electrolytic cells, the power consumption of electrolytic aluminum is reduced due to the good wettability of TiBz and molten aluminum; the service life of the electrolytic cell is extended. It can also be made into PTC heating and flexible PTC materials, which are the intensifiers of metal materials such as Al, Fe, Cu, etc.
Preparation of titanium diboride Self-propagating high-temperature synthesis (SHS): This method generally involves pressing the raw material mixture to be reacted into a block and then igniting the reaction at one end of the block. The huge heat released by the reaction makes the adjacent materials react, and finally forms a combustion wave spreading at a speed of v. Finally, with the advance of the combustion wave, the raw material mixture is converted into the final product. Due to the self-purification of the process of SHS, the product purity is high. Therefore, the obtained powder can easily be further sintered, and the external energy consumption is low. If combined with other special technical means, dense titanium diboride material can be directly prepared.
