Sodium tungstate (H2WO4) dispersion is a suspension formed by dispersing sodium tungstate particles in a solvent. Sodium tungstate is an inorganic compound with the chemical formula H2WO4. It consists of tungstate ions (WO4 2-) and hydrogen ions (H+).
The method of preparing sodium tungstate dispersion can be changed according to actual needs and conditions. A common preparation method is as follows:
Prepare Materials
Obtain sodium tungstate powder (H2WO4) and an appropriate solvent (such as water).
Weighing And Mixing:
According to the required concentration and volume, weigh an appropriate amount of sodium tungstate powder and add it into a clean container. Then, add an appropriate amount of solvent and mix well using a stir bar or a magnetic stir bar.
Decentralized Processing
To better disperse the sodium tungstate particles, sonication or other dispersion techniques can be used. The mixture is placed in an ultrasonic bath, and the particles are dispersed evenly by the action of ultrasonic waves. The treatment is continued for a period of time until the particles reach the desired state of dispersion.
Filter And Store
For larger particles or impurities, filter paper or other appropriate filters can be used to obtain a pure dispersion. Transfer the dispersion to a clean container and store in a cool, dry environment.
In the process of preparing sodium tungstate dispersion, safety operation and laboratory specifications should be followed. According to actual needs, the concentration of sodium tungstate, solvent selection, and the time and conditions of dispersion treatment can be adjusted to obtain the required properties and performance of the dispersion.
