Round Scratch Resistant Sapphire Crystal Glass , Sapphire Glass Scratch Proof

Size can be customized round scratch-resistant synthetic sapphire crystal

Description

Synthetic sapphire is made of bauxite (a type of aluminum oxide), which is mixed with oxygen and hydrogen to bring the material to a melting point of 2050°C. It takes about 15 hours to form sticks (crystalline aluminum) like "corundum". Then the stone is fired again at a high temperature of 1800°C to ensure the stability of the material. Then, the corundum-like material is cut with a very thin diamond polishing blade, and the crystal is cut into thin slices with a diameter of no more than 0.02 mm. The machine can be processed, and then the surface is polished to the required standard thickness, and then the high and low surfaces are processed. After polishing, it can be made into an arc or semicircular crystal surface.

Specification

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.
