Product Series
Seed holders for Sapphire Crystal Growth Thermal Fields
Product Introduction
Tungsten has a melting point as high as 3,420ºC, and features good strength and hardness, excellent high temperature performance, low resistivity, small expansion coefficient, and small electronic work function. It is a widely-used, high-temperature resistant metal.
Infused with a certain amount of alloying components, the collet can greatly improves its high temperature strength, creep resistance, service life and reliability.
Product Application
The sapphire crystal growth process takes place at over 2,200°C, and the tungsten seed clamp must have sufficient high-temperature strength to carry the weight of the crystal, and high enough purity to meet the requirements of a pure crystal growth environment. Moreover, it should be reliable for repeated use, and there should be stringent requirements for the dimensional accuracy of the collet to ensure a consistent growth direction.
