Tungsten crucibles are widely used in various fields due to their high melting point, high density, good wear resistance, and corrosion resistance. Especially in rare earth metal smelting, the performance and lifespan of tungsten crucibles are crucial. Traditional welded crucibles have weld defects that affect their service life. The sintered tungsten crucible, due to its high density and purity, solves these problems and has become the preferred choice in the rare earth smelting industry.
During the growth process of sapphire crystals, the high purity and absence of internal cracks of tungsten crucibles greatly improve the success rate of seed crystallization. At the same time, they play a critical role in controlling the quality of sapphire crystal pulling, de crystallization, sticking to the pot, and service life.
Quartz glass melting also requires a high melting point tungsten crucible as the core container to ensure stability and yield at high temperatures. Tungsten crucibles can not only withstand extreme high temperatures in these applications, but also ensure the purity of materials and product quality.
