Product Description

Fire is a common method in industry. Generally, ammonium secondary tungstate (APT) is used as raw material and obtained by thermal decomposition or slight reduction with hydrogen. Blue tungsten oxide can be obtained by slight reduction of WO3 by hydrogen, but the quality is not as good as that of APT
