Welcome to Know Sapphire~~
Synthetic sapphire is transparent single crystal 99.99% pure Al2O3 that exhibits a unique combination of physical, chemical,
electrical and optical properties: high thermal conductivity, high
strength and scratch resistance, hardness (9 on the Mohs scale),
transparent in wide range of wavelength, chemical inertness.
High crystal perfection, low reactivity, and appropriate unit cell
size make sapphire an excellent substrate in the semiconductor
industry for blue light-emitting diodes (LED).
Since Nobel Laureate in Physics Shuji Nakamura used the sapphire
substrate in 1990s for LED, the demand of sapphire crystal has been
growing rapidly.
It drives development of new markets like general lighting,
backside lighting in TV-sets, displays, consumer appliances,
aerospace and defense, and other applications
Sapphire adavantage physical property
- Medical and dental tools that require UV sterilization and curing
and IR thermal processing are typical applications where sapphire
windows and transparent tools excel.
- The melting temperature of sapphire bearings exceeds 2000°. The
lubrication of jewel bearings is a safe choice for the process of
contamination due to ash or debris that may accumulate in the
instrument.
- Sapphire bearings achieve extreme friction, long life and withstand
harsh environments are unbeatable
- Sapphire is suitable for use in acid or alkaline environments as
well as in high temperatures. Therefore, in demanding applications
such as petroleum and petrochemical, process control and medical
devices
Application area:
Used in hydraulic valves, hydraulic bearings, medical gas valves,
analytical instruments, gas chromatography FID detectors, pneumatic
regulators, high pressure injection, leak detection, inkjet, cell
counting and medical instruments, etc.
