Tungstic Acid

The formula is mWO3·nH2O. There are various known tungstic acids, which are polyorganic compounds in which tungsten trioxide WO3 is combined with each other and combined with water in different ratios and in different forms.

Appearance: The tungstic acid powder is yellow, the color is uniform, and the product has no visible inclusions.

Physical properties: The product powder passed through a 20 mesh to 80 mesh screen with a powder bulk density of 0.5-1.0 g/cm3.
