Tungsten Crucible Used In Opto-Electrical Kingdom 

As we all know, single crystal sapphire has a unique combination of physical, chemical and optical properties, allowing it to withstand high temperatures, high pressure, thermal shock, and water or sand erosion. They have been widely used in military infrared equipment, satellite space technology, high-intensity laser window materials.

Tungsten crucible is good at participating in development of sapphire single crystal growth, due to its multi-characteristic such as radiation resistance and endure high temperation etc.

Zhuzhou Jianfeng Special Metal Co.,Ltd is a leading manufacturer specialized in producing tungsten crucible and moly sheet. We have long term experience in heating zone for sapphire. Our tungsten crucible is mainly used in sapphire single crystal growth, optical device, optical industry and so on. At current, the market is very prosperous, especially  in photoelectric industry. We constantly provide products to some esteemed company in RUSSIA and USA. Now our crucible can produce 12 inch sapphire wafers. Make progress continuously is our goal. We hope that we have an opportunity to develop the market with who dedicate to such the prosperous kindom.
