To select a suitable solvent, factors such as the solubility of tungsten oxide particles, compatibility of solvents, and application requirements need to be considered. During the selection process, experimentation and testing is required to ensure that the solvent can effectively disperse the tungsten oxide particles and meet the required dispersion performance requirements. Solvents commonly used in tungsten oxide dispersions are as follows:
Water
Water is the most common and commonly used solvent with good solubility and environmental friendliness. For some water-soluble tungsten oxide particles, water may be the preferred solvent.
Organic Solvents
Including ethanol, isopropanol, methanol and other organic solvents. These solvents can increase the solubility of tungsten oxide particles to a certain extent and provide a suitable dispersion environment.
Water/Organic Solvent Mixture
Common mixed solvents include water/ethanol, water/methanol, etc. Mixed solvents can adjust the solubility and dispersion properties of tungsten oxide particles to a certain extent.
Organic Solvent System
For some tungsten oxide particles that are difficult to dissolve in water, organic solvent systems can be selected, such as N,N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), ethylene glycol, etc. These organic solvents can provide high solubility and dispersibility.
