Product Description
Isostatic Graphite-Photovoltaic
(1)CZ thermal field
In the thermal field of drawing monocrystalline silicon, isostatic graphite is mainly used to make heat preservation cover, heater, graphite crucible, diversion cylinder, graphite electrode and so on.
(2) Polysilicon thermal field
In the polysilicon thermal field, isostatic graphite is mainly used to make graphite base, ingot furnace and so on.
