Ammonium Paratungstate (APT) Use

Mainly used in the manufacture of tungsten metal powder like tungsten trioxide or tungsten blue oxide;the downstream products of metallic tungsten powder have tungsten material series, such as tungsten, tungsten and other electric vacuum materials; there are alloy series too, such as tungsten carbide alloy blade, alloy drill, alloy molds, etc.; and other wear, pressure, temperature and other machinery and equipment components.Tungsten oxide can be obtained by calcined tungstic acid or APTCalcined in air (oxidizing atmosphere) to obtain tungsten trioxideCalcined in weak reducing atmosphere can be obtained industrial blue tungsten oxide - a mixture of a lot of WO2.9 and a small amount of WO2.72 with traces of WO3 and WO2.
