Jingao Solar Holdings Co., Ltd. products

The single crystal furnace is a flexible shaft lifting equipment used for growing single crystals using the Czochralski (CZ) method. It melts polysilicon materials in a quartz crucible by heating them with graphite resistance heaters in an inert gas atmosphere below atmospheric pressure, producing high-quality, dislocation-free single crystals. JA Solar can now produce single crystal furnaces with a CZ capacity of 160 and above.

Graphite products are made from graphites formed through isostatic pressing, which are then machined into the desired shape and size using a lathe and milling machine. These graphite products play a critical role in the production of single crystal silicon, as they form an integral part of the thermal field in single crystal furnaces.
