Pressureless sintered silicon carbide crucibles have the characteristics of high temperature resistance, good thermal shock stability, low expansion coefficient, resistance to various strong acid and alkali corrosion, resistance to peeling, good anti-powdering property, and good high-temperature creep resistance. In addition, the heat conduction speed is fast, making the fired products heated evenly, effectively reducing energy consumption and accelerating the firing speed, and increasing the output. It is widely used in the sintering of lithium-ion battery materials, electronic components, magnetic materials, strongly corrosive items, and various ceramic powders.
