Sapphire Crystal Growth Furnace

Application of sapphire long crystal furnace

The composition of sapphire is alumina, which is blue because it contains trace elements titanium (ti4+) or iron (fe2+). It belongs to the trilateral system. The crystal morphology is often cylindrical, short columnar, plate, etc., and the geometry is mostly granular or dense block. The color is transparent to translucent, glass luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous body. Sometimes it has a special optical effect - Starlight effect. The hardness is 9, and the density is 3.95-4.1 g / cm3.

Sapphire is a single crystal of alumina, which has excellent mechanical, optical, chemical and anti radiation properties, so it is widely used in optical components and machinery manufacturing industries. At present, sapphire is also the main substrate material used in the production of blue and white LEDs. Because blue and white LEDs have the advantages of long service life, low power consumption and high luminous efficiency, LEDs have become the mainstream of lighting fixtures in the future.

Because tungsten and molybdenum materials have the characteristics of high temperature resistance and low pollution, they are widely used in the thermal field components of sapphire long crystal furnace, including crucible, crucible cover, heater, heat shield, support rod, base, etc.
