Tungsten copper sol gel method with hydrolysis and polymerization basic reaction, which are in preparation of high purity at a low temperature, evenly distributed, high chemical activity of single and multi-component mixtures. It is a metal alkoxide and its compounds as raw materials, under certain conditions hydrolysis medium and catalyst - the polycondensation reaction solution into a gel, and then by drying and heat treatment method of obtaining synthetic materials.

Tungsten copper plasma spraying is a kind of technique strengthening the material surface and surface-modified new multi-purpose precision spraying.

Nano cesium tungstate is newly developed nano material, chemical formula is Cs₂WO₄, it is dark blue powder, can be used as transparent insulating powder, it is the best inorganic nano materials for near-infrared optical absorption.
