Regional smelting method—Synthesis principle
The crystalline material is first sintered or pressed into a rod
shape, and it is rotated and lowered to the heater, the rod
material is melted, and the melting zone is in a floating state,
thereby obtaining a purified or recrystallized single crystal.
Features: The crystals produced by the regional smelting method
have very high clarity, and it is difficult to see obvious
identification features. This method is very costly and is mainly
used to produce materials for scientific and technological
purposes.
