Ammonium paratungstate thermal decomposition method producing ammonium metatungstate is the typical and main process to produce AMT by solid phase transition method.

Sodium tungstate and sodium molybdate are two different substances with their difference reflecting in physical, chemical property and application.

Sodium tungstate fire proof material can be used as coatings for wood, fabric and other flammable materials and wooden architectural.

Testing method of tungsten content in sodium tungstate, which is using cinchonine hydrochloride to separate tungstic acid, then calcine to get tungsten trioxide, weight, colorimetric to calculate tungsten content.

Reproduced tungsten carbide powder refers to WC which obtained from waste hard alloy, can be divided into four grades of WCH-1, WCH-2, WCH-3, WCH-4 depending on raw material.

Sodium tungstate solution is an aqueous solution of solid sodium tungstate, the raw material of ammonium paratungstate (APT), ammonium metatungstate (AMT) ect.

Nickel based tungsten carbide powder mainly refers to add tungsten carbide powder (WC) on the basis of self-fluxing nickel-based alloy to enhance its hardness and wear-resistant, can be used for surface spray of oil drill pipe joints, reamers ect., with preparation methods of atomization, mechanical mixing and sintering method.

Wide specification tungsten powder is a kind of tungsten powder, whose grain size are not so gathered in a grain size.

Of the highest quality and purity, the specially prepared crystalline tungsten powders produced at Chinatungsten Online are large particle size tungsten powders beyond the range of the FSSS, classified by mesh size.

Ultrafine tungsten carbide powder is grain size < 1um.
