Quartz crucible of arc melting used for semiconductor industry is the essential basic material for pulling monocrystalline silicon and developing L S I circuit. It has the advantages of high purity, high temperature resistance with big size, good thermal insulation, economization on energy, quality stability etc.
We also can produce various specifications of transparent and translucent crucibles. Crucibles can be produced according to the standard or produced on customer's required specification and shape.
