The concentration of tungsten oxide dispersion can vary according to specific applications and needs, and there is no fixed standard value. Typically, the concentration is adjusted according to the desired particle concentration and application requirements. The concentration can be expressed by the mass or volume content of tungsten oxide particles in the solution. Common expressions include mass concentration (such as g/L) and volume concentration (such as volume percentage). The choice of concentration is also influenced by the type and concentration of dispersant. The existence of dispersant may affect the dispersibility and stability of particles, therefore, the influence of dispersant should be considered comprehensively when adjusting the concentration. The concentration of tungsten oxide dispersion can be calculated in the following two common ways:
Mass concentration of tungsten oxide dispersion
The mass concentration indicates the mass of tungsten oxide contained in a unit volume (usually liter). Calculated as follows:
Mass concentration (g/l) = (tungsten oxide mass (g)/solution volume (l))
For example, if 1 gram of tungsten oxide is dissolved in 1 liter of solution, then the mass concentration is 1 gram per liter.
Volume concentration of tungsten oxide dispersion
The volume concentration indicates the volume percentage of tungsten oxide in the solution. Calculated as follows:
Volume concentration (volume percent) = (tungsten oxide volume (ml) / solution volume (ml)) × 100
For example, if 10ml of a suspension of tungsten oxide is dissolved in 100ml of solution, then the volume concentration is 10%.
When actually measuring the concentration, a weighing balance, a volumetric meter or other appropriate experimental equipment can be used to accurately measure the mass or volume of tungsten oxide. At the same time, it is also necessary to ensure uniform mixing of the sample and proper dilution (if necessary) to obtain the desired concentration. In practical applications, the concentration of the tungsten oxide dispersion can be adjusted as needed. Lower concentrations may be better for some applications, while higher concentrations may be better for others. When selecting and using tungsten oxide dispersion, the appropriate concentration range should be determined according to specific experimental conditions, objectives and performance requirements.
