The physical property test of ammonium metatungstate mainly includes the following aspects:
Properties: Ammonium metatungstate is usually white powder.
Physical Properties: The product can usually pass 60 mesh screen.
At 25℃, the pH value of the aqueous solution of Ammonium Metatungstate is usually between 2 and 4, showing its acidity. Ammonium metatungstate has a high melting point of about 240°C, indicating that it is a solid at room temperature.
Solubility: Ammonium metatungstate is easily soluble in water, and can form colorless solution in water. 25°C, the solubility of ammonium metatungstate is ≥1.85Kg/L H₂O, which shows that its solubility in water is strong.
Water inadmissible substance: The content of water inadmissible substance in ammonium metatungstate should be ≤0.03%, which is an index to measure its purity.
Packing: Ammonium tungstate is usually packed in iron drums lined with plastic bags or cloth bags, with a net weight of 100kg or 200kg per drum; or in 1000kg tons bags on pallets. This is the conventional way for its transportation and storage.
Others: In practical application, other physical properties such as particle size, density, specific surface area and other physical properties of ammonium metatungstate may also be examined to meet the application requirements in different fields.
To sum up, the physical property tests of ammonium metatungstate cover various aspects such as traits, physical properties, solubility, water intolerance, packaging and so on. These tests help to ensure that the quality and performance of ammonium metatungstate meet the requirements of specific applications.
