X-ray protective tungsten alloy screen is made of high quality tungsten based alloy with excellent X-ray radiation shielding performance, which is mainly applied for enhancing the protective effect of patients’ radiology diagnosis and treatment. Also, such a screen can be used in industrial radiation protection.

Ammonium paratungstate (APT) as an important precursor in tungsten industry. It is the raw material for the majority of tungsten products. For example, tungsten trioxide (WO₃), tungsten blue oxide, tungstic acid and ammonium metatungstate, etc. These are all intermediates by subsequent calcination and/or reduction of APT. Another significant middle product is monoclinic W₁₈O₄₉, (WO_2.72), one of the tungsten suboxides, is an important intermediate product of WO₃, influencing significantly the morphology of the tungsten powder end-product. W₁₈O₄₉ crystallises in needles and agglomerates of needle-like crystallites. This is true for the formation by vapour transport, in oxidative, and reductive atmospheres and for the transformation in the solid phase.

Fabrication of cemented carbides is the main use of tungsten carbide (WC). This application uses powders with a wide range of mean particle size. Submicron grained cemented carbides use very tiny tungsten carbide powders, which is very useful as catalyst. Cemented carbides of submicron carbide grains show an improved toughness to hardness ratio.

WO3 composite coating is a good choice for formaldehyde degradation. It is the photocatalytic performance of tungsten trioxide that make WO3 composite coating have the performance of degrading formaldehyde, thereby improving air quality and human health.
