Synthetic 20mm 40mm Sapphire Crystal With Excellent Chemical Stability And Light Transmittance

Sapphire synthetic crystal with excellent chemical stability, mechanical properties and light transmittance

Description

Synthetic sapphire (Corundum or Al2O3) single crystal is a highly trusted material with its excellent chemical stability, mechanical property, and light transmission. It is often used in aggressive environments where reliability, optical transmission and strength are required.

Specification

Flame melting——Synthesis principle

Pure alumina (Al2O3) powder can produce colorless synthetic corundum, adding a small amount of color-causing elements to obtain different colors.
Process flow
① Al2O3 powder is screened, and the powder falls along the inner tube of the blowing pipe facing downwards.
② When the temperature of the hydrogen-oxygen flame reaches the melting point of corundum, the corundum melts and the molten powder falls onto the platform.
③ The platform gradually lowered, and the falling molten powder formed pear crystals.
④ It takes about 10 hours to form synthetic corundum with a diameter of 20mm and a length of 100mm.
⑤ After the growth is over, the crystal cools down. During the growth process, considerable stress is generated inside the crystal. Therefore, if the heating is stopped, the crystal may split into two halves along the longitudinal direction (//C axis). Before cutting, hit the crystal with a hammer and split it, which can also release part of the stress.
