As we all know, the tungsten crucible is a kind of crucible that made of metal tungsten, it has the characteristics of high melting point, high hardness, good high temperature performance, low resistivity, low coefficient of expansion and small electron emission, which is an important component of sapphire crystal growth furnace in today’s market. Zhengzhou Sanhui tungsten crucible products have been used by the national more than 100 sapphire crystal factories and quartz glass factories for many years, the effect is also very good, and it gets a good evaluation of the user.

According to the different sizes and using conditions, the tungsten crucible on the market has different production processes. Today, the common crucible type is round square type, long type, V type and so on. The tungsten crucible can be roughly divided into four types according to production process: sintering forming, welding forming, stamping forming and spinning forming. At present, the sintering forming products are widely used. For small tungsten crucible, it can use the forging tungsten rod turning or be formed by stamping.

Some of the characteristics and using performance of tungsten crucible must have a good understanding, here, but also hope that everyone should be reasonable in the processing or using.
