Single-crystal ammonium paratungstate has properties of good fluidity, high bulk density, small and uniform grain gaps in the blank, few mechanical defects and high compaction density. It also has excellent physical properties such as good compression resistance, tensile resistance, impact resistance, shear resistance and fracture strength. Therefore, single-crystal ammonium paratungstate is an ideal raw material for the production of high-performance tungsten materials such as tungsten powder, tungsten wire, tungsten carbide microdrill, tungsten carbide tool, and tungsten alloy ammunition.

Studies have shown that due to genetic relationships, the crystal properties of ammonium paratungstate (APT), such as crystal morphology, average particle size and particle size distribution, bulk density and fluidity, have a great influence on the material properties of subsequent powder metallurgy products - tungsten powder, tungsten wire, and tungsten alloy, etc. For example, the life of the holding-up hammer produced by the single crystal APT is 2-3 times that of the polycrystalline APT. Therefore, the research on the preparation technology and preparation principle of single-crystal ammonium paratungstate powder is a key topic.
