Development of Tungsten Crucible in China

China is one of the richest tungsten resources storage countries in the world. Therefore, as deep processing product of tungsten, tungsten crucible industry has been continuously developed in China. The main applications of tungsten crucible in China are rare earth smelting, quartz glass, electronic spraying, crystal growth, etc.

Nowadays, our country has a production capacity for some conventional tungsten crucible, but there still exist some problems for the high-tech products. For example, the manufacturing technique for complex shape of the tungsten crucible is relatively rare, but such products play an important role in the area of high technology. And for instance, quartz glass has been widely applied in laser technology, astronomy and sophisticated technology. With the rapid development of modern technology, as the core components of quartz glass, tungsten crucible has a wide range prospects for development. The next few years, the development direction of the tungsten crucible will be large-size, high-quality, low-cost characteristics of tungsten crucible

With the rise of the tungsten industry in our country, the exploitation of tungsten resources has become a major problem. Our country has been exporting tungsten raw materials for a long time, which will affect the production of tungsten crucible. On the other hand, the utilization of the tungsten crucible is not enough. Tungsten Crucible has a long life time for using so that users can reuse it for many times. It can not only save costs but also protect the ecological environment. In addition, changing the export structure of the tungsten crucible which can save a lot of foreign exchange and improve our economy.

In recent years, the rapid development of chemical vapor deposition of can produce complex shape tungsten products in China. This is an important research direction of pure tungsten manufacturing technique. Such tungsten crucible that made by chemical vapor deposition process will be gradually on the market. Isostatic - sintering process in our country has reached the international advanced level and the scale of China's tungsten crucible development would be expanded with continuously improvement of the process. With the deepening of China's tungsten crucible research, international influence of domestic tungsten crucible is gradually rising, the tungsten crucible industry of China will occupy a major position in the international area in the future.
