Application areas:

One of the main raw materials of vacuum-coated conductive evaporation boat, composite ceramic material. It can be used as an important component of multi-component composite materials, and is composed of TiC, TiN, SiC and other materials to make various high-temperature resistant parts and functional parts, such as high temperature crucibles and engine parts. It is also one of the best materials for making armor protection materials, ceramic cutting tools and molds. Finishing tools, wire drawing dies, extrusion dies, sand blasting nozzles, sealing components, etc. can be manufactured. Aluminum electrolytic cell cathode coating material. Due to the good wettability of TiB2 and metal aluminum solution, TiB2 can be used as the cathode coating material of the aluminum electrolytic cell, which can reduce the power consumption of the aluminum electrolytic cell and prolong the life of the electrolytic cell. It is made into PTC heating ceramic material and flexible PTC material. It is safe, energy-saving, reliable, easy to process and form. It is a new high-tech product of various types of electric heating materials. Conductive ceramic material.
