Products introducing
      Quartz ceramics crucible is used as a container of loading polycrystalline silicon materials during the production of solar energy polycrystalline silicon ingot casting,it will bemelted under 1550°C,crystallized and produced polycrystalline silicon ingot casting ,it is the key consuming part during the production of polycrystalline silicon ingot casting,adopting traditional quartz ceramics slip casting forming technology.And using good quality melting quartz as raw materials,the product has the characteristics of high purity,good heat stability,good antiseptic function,compressive strength and bending strength are big,precision of geometric size is high,and service life is long,etc.
