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

Tungsten trioxide and calcium hydroxide reaction will produce calcium tungstate CaWO₄, it is also called artificial scheelite which is used to produce APT and WO₃.

Titanium tungsten powder is main component of denitration catalyst, a white powder insoluble in water, without toxic substance of vanadium pentoxide (V₂O₅), belongs to safe new materials, its manufacturing process including preparation of meta-titanic acid, titanium tungsten composite powders and post-treatment.

Tungsten trioxide can be applied in hydrogen desulfurization catalyst, SCR denitration catalyst, photocatalyst.

Tungsten trioxide hydrogen reduction producing tungsten powder uses two steps method which is used for batch production.

Silver phosphotungstate photocatalyst has excellent catalytic performance, environmental friendliness and other advantages to be widely used, and can be synthesized by microwave solid-phase synthesis and precipitation method.

Phophotungstic acid application includes catalyst, printing and dyeing, coloring agent, biological sample dyeing, protein precipitation and bipolar ion exchange membrane.

Copper phosphotungstate is a product of reaction between phosphotungstic acid and copper nitrate, used as catalyst for petrochemical oxidative desulfurization, catalytic synthesis of acetyl acetal, tetrahydrofuran.

Bismuth phosphotungstate is a bismuth salt of phosphotungstic acid, as a catalyst with green powder, chemical formula of BiPW₁₂O₄₀, generated by metathesis and microwave solid-phase synthesis method from phosphotungstic acid and bismuth trichloride.
