Product Series

Tungsten Tray for Sapphire Growth Thermal Field

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.

Product Application

The gem crystal growth process needs to provide a melting temperature in excess of 2,200°C, which requires extremely high high-temperature strength and high-temperature creep resistance performance for thermal field materials. Tray products made of tungsten materials meet the structural stability requirements of the thermal field during the crystal growth process.
