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, dislocationss-free single crystals. JA Solar can now produce single crystal furnaces with a CZ capacity of 160 and above.
