How to prepare ammonium paratungstate? At present, ion exchange method and extraction method are mainly used to produce ammonium paratungstate (APT) by domestic manufacturers.

Single-crystal ammonium paratungstate has a wide application as it has good fluidity, excellent tensile resistance and fracture resistance. And therefore single-crystal APT is used to prepare tungsten powder, high-performance tungsten materials such as tungsten wire, weights, armor bombs, micro-drills, and CNC blades, etc.

The researchers proposed a preparation method of high-purity ammonium paratungstate. This process optimizes the original high-purity APT production process and reduces production costs.

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.
