Silicon carbide crucible has the characteristics of high volume density, high temperature resistance, fast heat transfer, acid and alkali resistance, low carbon and environmental protection, high high-temperature mechanical strength, and high oxidation resistance. With the promotion of new energy sources, battery materials are gradually developing. The production of battery materials urgently requires silicon carbide yards with good thermal conductivity, high temperature resistance, and corrosion resistance as heating vessels. Our company has successfully developed a new large-scale reaction sintered silicon carbide yard as a heating container for battery materials.
