In recent years, some new materials with tungstate photocatalytic properties have been discovered, tungstate material belongs to semiconductor materials, because of its unique structure and physical and chemical properties, so it has a bright prospect of application in magnetic materials, catalyst and scintillation materials.

Violet nano tungsten oxide is the optimum raw material for producing ultrafine tungsten nanopowder with uniform grain size now as violet tungsten oxide is elongated columnar micro crystals with ammonium paratungstate fake crystalline accumulated. Its sharp split pore structure forms good permeability and can realize the fast recovery of dry hydrogen. At the same time, it can avoid generating β-W and α-W in WO2 period.

Yellow nano tungsten oxide is prepared by hydrothermal method using tungstic acid as precursor and thiourea as basic adjuvant. The influence of different reaction conditions on the morphology and gas sensitivity of yellow tungsten oxide can be studied by changing the preparation temperature of the precursor and the content of thiourea.

Dark blue nano tungsten oxide is a kind of semiconductor material with good chemical stability that may be applied in manufacturing semiconductor devices and electronic material of integrated circuits.

Blue tungsten oxide nanopowder may be applied in the electronics industry. Electronics is the science of controlling electrical energy electrically and deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies.

Blue nano tungsten oxide’s price affecting factors are mainly listed as follows:

Micro fine blue tungsten oxide’s XPS experiment is using a surface-sensitive quantitative spectroscopic technique to systematically analyze the valence changes of blue tungsten oxide during tungsten powder producing from tungsten ore. XPS is the short for X-ray photoelectron spectroscopy.

TBO is the abbreviation for tungsten blue oxide. It is not a defined tungsten compound, but a powdery mixture of multiple tungsten compounds whose chemical composition and physical properties are changing. Tungsten blue oxide is gradually replacing traditional tungstic acid and yellow tungsten oxide (tungsten trioxide) to become an important tungsten intermediate compound.

 High quality tungsten carbide powder has the advantages of high melting point, high hardness and good stability. It has a wide range of applications and can be prepared by direct reduction carbonization technology.

 Coarse crystalline tungsten carbide powder has some special properties and special applications that are different from those of medium and fine grain size tungsten carbide powders. It has gained increasing attention in various industrial fields.

 The traditional method for preparing coarse crystalline tungsten carbide powder is to use tungsten trioxide for high-temperature reduction to obtain particulate tungsten powder, and then coarse-grain tungsten powder for high-temperature carbonization to obtain coarse-grained tungsten carbide powder.

The production process of coarse crystalline tungsten carbide powder, in addition to the traditional high-temperature reduction high-temperature carbonization method, has also appeared in the high-temperature carbonization of medium-grain tungsten powder and high-temperature carbonization of fine-grain tungsten powder; aluminum heat reduction carbide method coarse tungsten carbide powder technology; In addition, special graded method to obtain high-quality coarse-grain tungsten carbide powder and other processes.
