Background and overview of calcium hexaborate
Calcium hexaboride, a chemical called calcium borate, is mainly synthesized through carbothermal reduction, self-propagation, and other means. A material research institute in China and some universities have certain synthesis research technologies. Calcium hexaboride is a black-gray powder or particle. The melting point is 2230 ℃, the relative density is 2.33 g/cm, and it is insoluble in water at 15 ℃. Silicon boride is a glossy black-gray powder with a relative thickness of 3.0g/cm and a melti
