A Brief Introduction of Tungsten Granule

Tungsten granule is a flux which is major applied to the high frequency infrared carbon and sulfur analyzer. Therefore, tungsten granule also known as tungsten flux or pure tungsten flux. After processing the tungsten metal into some tiny particles, tungsten flux can be produced. The purity of tungsten granule is very high, it can reach more than 99.95%. And the size of tungsten granule is 20-40 mesh. As a flux, tungsten granule has good fluxing effectiveness and a stability analysis. Tungsten granule has been widely applied to the electronic chemical industry.

The shape of tungsten granule is polyhedral particles with bright gray color. Tungsten granule is mainly made of above tungsten. Tungsten is easily oxidized into tungsten oxide which belongs to acidity element and benefits the release of carbon dioxide and sulfur dioxide. In 1781, tungsten is a kind of mineral which was found by the Swedish chemist and mineralogist named Clance Tate.

There exist very low impurity elements in tungsten granule. The carbon element is less than 0.0008%, the sulfur element is less than 0.0005%, and an oxygen element is less than 0.05%. Therefore, tungsten granule has a high purity. In the most cases, tungsten granule is packed 1000g a bottle. The weight would be different due to the different specifications.

With the rapid development of modern science and technology, according to the demand of the production process, tungsten granule is widely applied to metallurgy, welding, and other analytical testing process. Nowadays, tungsten flux is the most indispensable fluxing materials for Infrared analyzer or other analyzers to measure the content of carbon and sulfur. It would release about 195.8 kcal / mol of heat when it start to oxidized with oxygen under a temperature greater than 650 ℃. Therefore, it has a strong fluxing effectiveness.
