Prepare Uniformity Superfine WO3 by Spray Drying

Article Preview

Abstract:

Precursor of tungsten was obtained by spray drying process with high purity APT crystal liquor as material. The precursor was analysized by electron microscopy and X-ray. A suitable spray drying process was found through the morphology and powder structure. The influence of atomization disk rotational speed, the concentration ratio of ammonia to WO3 in APT liquor and APT liquor’s concentration on particle size, structure and morphology of the ball precursor were studied. Uniformity superfine WO3 was obtained from precursor by calcined.
