Yellow Tungsten Oxide Properties

Yellow tungsten oxide  is a stable oxide crystal powder of tungsten. The characteristics of yellow tungsten oxide include: the density of 7.2 ~ 7.4g / cm³, the melting point of about 1470 ℃.

Its boiling point between 1700 -2000 ℃, with high hardness, strength and wear resistance, good electrical conductivity and thermal conductivity, small expansion coefficient, normal temperature in the air to maintain a stable state. Due to the different size of the yellow tungsten crystal, yellow tungsten is yellow or green, although the appearance is not the same between the two, the characteristics of the two are similar.

In the production process of modern tungsten products, yellow tungsten oxide production process is mainly through solid state reduction, atomization, electrolysis and chemical methods to prepare metal powder. Yellow tungsten oxide is generally used in the production of chemical products, such as paints, industrial catalysts, etc ; However the yellow tungsten oxide as an intermediate product of tungsten that a large number of yellow tungsten oxide is mainly used in the preparation of tungsten metal powder and tungsten carbide powder, and thus for the tungsten metal products processing and production, at the same time due to the vigorous development of the alloy material industry, making a large number of yellow tungsten oxide used in the modern process of tungsten alloy products processing.
