二硼化钛 - Use
Open Data Verified Data
titanium diboride and its composites have broad application prospects. Titanium diboride can be used with TiC, TiN, SiC and other materials to form composite materials, which are used for wire drawing die, extrusion die, sand nozzle, sealing element, cutting tool, armor protection and other materials, ideal materials for functional devices. As the cathode material of aluminum electrolysis cell, the power consumption of electrolytic aluminum is reduced and the service life of the electrolytic cell is prolonged due to the Good wettability of TiBz and metal aluminum liquid. The PTC Fever material and the flexible PTC material, which are reinforcing agents for metal materials such as Al, Fe, and Cu, can also be manufactured.

| use | powder is used for rocket nozzles, electrical contact and high temperature electrode materials, and can also be used as abrasives. conductive ceramics, tool ceramics, conductive wear-resistant and corrosion-resistant coatings v conductive composite materials. Using titanium diboride (TiB2) and boron nitride (BN) to make conductive boron nitride (evaporation boat) is the main component of vacuum aluminizing equipment. Ceramic cutting tools and their components. Titanium diboride ceramics are manufactured 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 multi-component composite materials. Titanium diboride can be used as a composite material for cutting tools with TiC , TiN , SiC and other materials. 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 electrolysis cathode material. Used as cathode material for aluminum electrolytic cell, due to the good wettability of TiB2 and molten metal aluminum, the power consumption of electrolytic aluminum is reduced and the life of the electrolytic cell is prolonged. It can also be made into PTC heating material and flexible PTC material, which is a fortifier for A1, Fe, Cu and other metal materials. Used as rocket nozzle, electrical contact, electrode material, etc. |
| production method | boron carbide method is also called carbothermal reduction method. its 2TiO2 B4C 3=2TiB2 4CO vapor deposition method uses TiCl4 and BCl3 as raw materials, and the deposition temperature is 800~1000 ℃ with H2 participation, which can produce abrasive grade and electronic grade products, tiCl4 2BCl3 5H2 = TiB2 10HCl |
