Technical Description of Tungsten Oxide Powder

Nano tungsten oxide powder is prepared by high frequency plasma gas phase combustion method, with high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual organic impurities, low loose density, easy to disperse, nano tungsten oxide has gas sensitivity, used for the detection of carbon dioxide, ammonia and other gases.


Tungsten oxide thin film gas sensor and tungsten oxide nano particle sensor have been prepared. The discovery of nano sensor greatly improves the detection of low concentration gas.

Application of Tungsten Oxide Powder

  1. Nanometer tungsten oxide is used for many purposes in daily life.  It is often used in industrial X-ray screen phosphors and in the manufacture of tungstate for fireproof fabrics.  Because of its rich yellow element, nano-tungsten oxide is also used as a pigment in ceramics and paints;


  2. Nano tungsten oxide has been employed in the production of electrochromic Windows, intelligent Windows.  These Windows are electrically switched glass, with light transmittance varying with applied voltage.  This allows users to tone their Windows through changes in the amount of heat or light.  Another use is to use inert metals in high density. The better use of these devices was during the conflict between Israel and the Gaza Strip in 2008-2009;


  3. Nano tungsten oxide part of the production of chemical products, such as paint and coatings, oil industry catalyst;  But tungsten oxide is a kind of intermediate products, a large number of tungsten oxide is used for metal tungsten powder and tungsten carbide powder, and then used in the manufacture of metal tungsten products in the production, application and production of tungsten alloy products, and a large number of the tungsten copper, nickel, tungsten, tungsten nickel iron, silver, tungsten rhenium tungsten and tungsten thorium, etc., and wide application in the industrial field is based on the material of tungsten production of various grades and USES of cemented carbide products;


  4. Nano tungsten trioxide is used for solar absorption materials and stealth materials, excellent gas sensitive semiconductor materials and catalyst materials with special catalytic performance, but also used for ultrafine tungsten powder and fire prevention materials, also used as a colorant in ceramics, etc.
