Arc Quartz Crucible

Description

High purity quartz sand – high purity graphite  mold   vacuum arc melting – natural cooling stripping – quartz crucible preliminary testing – cold processing sandblasting, cutting, chamfering – quartz crucible secondary testing – ultra-clean cleaning, ultrasound, high-pressure spray, automatic drying. Heating, baking, spraying, quartz crucible, three tests, vacuum packaging, finished product storage

At present, the crucible production coating technology has been used by most of the manufacturers, which is to coat the surface of the ordinary quartz sand dissolved crucible with a layer of barium dioxide solution to form a dense layer, the dense layer can prevent the reaction between silicon and quartz crucible during the high temperature pulling process of single crystal silicon, and improve the crystallization rate.
