At present, in order to prepare tungsten products with high density and high temperature, the pressing and forming properties of tungsten powder are required. Therefore, it is very important to optimize the compacting and forming properties of tungsten powder.

In tungsten fluoride, tungsten hexafluoride (WF6) is the only stable and industrialized production of varieties. It is an important raw material in modern electronics industry. It can be used to produce high-purity tungsten powder as raw material for metal tungsten chemical vapor deposition (CVD) process, especially the WSi₂ made from it can be used as wiring material for large-scale integrated circuit (LSI).

Tungsten is an important thermal spraying material. Thermal spraying technology uses heat source to heat the spray material to melt or semi dissolve state, and spray at certain speed to deposit the coating on the pretreated substrate surface. The thermal spraying technology makes a special working surface on the surface of the ordinary material. 

Hard alloy with high hardness hard tungsten carbide micron metal powder as the main ingredient, with cobalt (Co), nickel (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction furnace in sintering, different tungsten content plays a key role in the performance of the alloy. The detection requirements must be accurate and reliable, the test for the tungsten content of hard alloy mainly has the gravimetric method, colorimetry and atomic absorption spectrometry.

Tungstic acid is acidic substances a yellow powder, tungsten trioxide containing about 90%, also contains trace tin, molybdenum, silicon, calcium, iron, manganese, potassium, sodium, chlorine, phosphorus, sulfur, arsenic, antimony, magnesium and other elements, is the raw material for the production of ammonium paratungstate.

With the development of the subsequent product process of tungsten, tungsten wire, tungsten powder, tungsten bars and other high-end hard alloy material of ammonium paratungstate rising, ammonium paratungstate zero grade existing national standard has been unable to meet the requirements of high-end hard alloy, not only the impurity and physical of ammonium paratungstate can put forward certain requirements, and part of the production of high-end products enterprises to individual impurity elements proposed particularly stringent requirements.
