Preparing Ultrafine Tungsten Powder By Purple Tungsten Oxide

Before the 1950, at home and abroad tungsten powder production to more acid and yellow tungsten raw materials for production, to 60 to 70 years, the United States, France, the Netherlands, the United Kingdom and many other countries, has generally adopted a blue tungsten acid as raw materials to replace the production of tungsten and tungsten yellow powder. In the late 1980s and early 1990s, has been completely replaced with tungsten blue and yellow tungsten acid to produce tungsten powder, so now when using the traditional process of ultrafine WC powders, the choices are basically oxide precursor Blue tungsten. Another new purple tungsten tungsten oxide, its physical indicators than blue tungsten has some improvements and enhancements, blue tungsten is a more than suitable for the production of ultra-fine powder and WC W oxide precursor powder.

Choose purple tungsten as a raw material in the traditional process conditions, can get good performance ultrafine W powder, resulting in high-quality ultrafine WC powder. Purple Tungsten W is a production of ultra-fine powder and WC powder oxide precursor fit. Use purple tungsten materials prepared for WC particles of small size and uniform particle size distribution and good, no structural gathered clumps, WC complete crystalline grains. Purple tungsten raw material, whether it is produced by W powder or WC powder, its physical properties are superior materials for blue tungsten products.
