The physical properties of ammonium metatungstate (AMT) mainly include the following aspects:
Appearance of ammonium metatungstate
Ammonium metatungstate is usually a white crystalline powder or slightly yellow.
Solubility of ammonium metatungstate
Ammonium metatungstate is easily soluble in water, but insoluble in ethanol. At 20°C, its solubility in water is high, and the solubility increases with increasing temperature.
Density of ammonium metatungstate
The specific density value may vary slightly depending on factors such as purity and crystal state, but ammonium metatungstate usually has a larger density.
Crystal structure of ammonium metatungstate
Ammonium metatungstate has a complex crystal structure consisting of metatungstate anions and ammonium cations.
Melting point of ammonium metatungstate
Ammonium metatungstate does not have a fixed melting point because it undergoes multiple phase changes and decomposition processes when heated. Usually, thermal decomposition begins at around 100°C.
Volatility of ammonium metatungstate
Ammonium metatungstate has low volatility at room temperature and pressure, but it will decompose and produce gas under high temperature conditions.
These physical properties may vary slightly depending on factors such as preparation conditions, purity, ambient temperature and humidity. In practical applications, it is recommended to refer to specific product manuals or related literature. If necessary, please visit our website or contact our sales engineer at CTIA GROUP LTD.
