Tungsten Powder Prepared from Violet Tungsten Oxide

Violet tungsten oxide is suitable for the preparation of tungsten powder with small granularity and good properties, so as to make high-quality cemented carbide. It has high chemical activity and high rate of hydrogen reduction.

Tungsten powder is widely used in the processing of hard alloy, tungsten alloy and pure tungsten products. Here is its application as following as:

1. Pure tungsten powder can be processed into materials in different shapes such as wire, rod, tube and plate. And these materials can be used to make electric light bulbs, electronic tube components and arc welding electrodes;

2. Tungsten powder can be mixed with other metal powder to make various tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy and tungsten alloy with high density. Among them, tungsten copper alloy can be used as electrical contact materials, and high-density tungsten nickel copper alloy can be used as radiation shields.

3. Tungsten powder can be made into tungsten carbide powder, so as to make various cemented carbide tools such as turning tool and moulds. This is an important application of tungsten powder.

In order to make tungsten powder better applied in the processing of hard alloy and other products, the raw material selected is extremely important. Violet tungsten oxide is an ideal material for the preparation of tungsten powder. It has needle structure, with the rough particle surface and large internal gap. The unique structure makes violet tungsten oxide has high chemical activity and high rate of hydrogen reduction. In the reduction process, hydrogen can penetrate better and water vapor can release well. The whole production process is efficient.

As for the prepared tungsten powder from violet tungsten oxide, it is ultrafine and of high quality. Violet tungsten oxide has high application value in the preparation of tungsten powder.
