Uses of titanium diboride
Conductive composite material. Using titanium diboride (TiB2) and boron nitride (BN) to make conductive boron nitride (evaporation boat) is the main component of vacuum aluminum plating equipment. Ceramic cutting tools and their parts. Manufacture of titanium diboride ceramics for wire drawing dies, extrusion dies, sandblasting nozzles, sealing elements, cutting tools, etc. Composite ceramic materials. It can be used as an important component of multiple composite materials. Titanium diboride can be used as a composite material for cutting tools with TiC, TiN, SiC, and other material groups. It can also be used as a component to make armor protection materials. It is a variety of high-temperature parts. , The best material for functional devices. Aluminum electrolytic cathode material. It is used as the cathode material of aluminum electrolytic cells. Due to the good wettability of TiB2 and metal aluminum liquid, the power consumption of electrolytic aluminum is reduced and the life of the electrolytic cell is extended. It can also be made into PTC heating materials and flexible PTC materials, and it is a strengthening agent for metal materials such as Al, Fe, and Cu.
 
Preparation method of titanium diboride sample
1. Mix tetra butyl titanate and 2,4-acetylacetone at a molar ratio of 0.2 to 0.3, and then dilute with ethanol.
2. Heat the solution prepared in 1 at 120°C for 2 hours to remove 2,4-acetylacetone and ethanol to make it a better sol.
3. Slowly add boric acid to the sol with stirring, then the milky white TiO2 is formed.
4. Then use phenolic resin as a carbon source to add to the formed binary sol, heat for 2h in an environment of 100C, and let the water and ethanol evaporate to obtain a gel.
5. Put the obtained dry gel powder in an environment of 80C for 12 hours. Experimental method: heat the obtained gel precursor at a high temperature at 1300-1400°C for 1-2h, the size of TiB2 powder is 100-200nm, and there are by-products TiC and TiO2.
