Prepare raw materials → fill raw materials and set up seed crystals → vacuum the furnace body → heat the furnace body (the furnace body is added with molybdenum heat shield and tungsten heat shield) → raw material melting → fusion seed crystal → crystal neck growth → crystal growth → crystal and crucible Separate (most of the crucibles inside are resistant to high temperatures.)→Cooling→Take out the crystals. boule crystal。

One is the crystal growth process from the former Soviet Union: the Kyropoulos method;

The other is the crystal growth process from the United States: the hydro-heat exchange method.
