Clear Transparent Synthetic Sapphire Crystal , Thin Strip Custom Sapphire Glass
Advancement On sapphire Crystal compare with other glass
1) High temperature resistant, Sapphire Round / Rectangular Optical
Window can work under 1200°C continuously, and in short time can
even work under 1450°C, its softening temperature is 1650°C, and
the melting temperature is 1750-1800°C.
2) Corrosion-resistant, Except hydrofluoric acid, Quartz Plate Of
Optical Grade do not react with any acid and base except
hydrofluoric acid. the stability is 30 times of the ceramic, and
150 times of stainless steel.
3) Excellent thermal shock stability
4) High transmission to 85%
5) Electric insulation, it is 10000 times of usual glass

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.
