Molybdenum Crucible Molybdenum crucible is widely used in metallurgy, chemical industry and rare earth manufacturing enterprises as a container for melting metals and alloys. In recent years, with the more and more serious pollution caused by the use of traditional resources in China, the development of new green energy has become a top priority, which is more obvious in the monocrystalline silicon, polycrystalline silicon, sapphire preparation industry. The new energy raw materials such as silicon and sapphire are prepared at very high temperature, so molybdenum crucible with very high temperature resistance is usually used.
