The following are the technical indicators of some common tungsten oxide dispersions. The selection and requirements of specific indicators will vary according to different application requirements and preparation methods. The technical indicators of tungsten oxide dispersion can include the following aspects:
Tungsten Oxide Dispersion Particle Size
The size of the tungsten oxide particles in the tungsten oxide dispersion is an important indicator. It is usually described by the average diameter or particle size distribution of particles, which can be measured by methods such as particle size analysis.
Dispersibility of tungsten oxide dispersion
Dispersion describes the degree of uniform dispersion of tungsten oxide particles in the liquid phase. Good dispersion means that there is no obvious agglomeration or sedimentation between particles, which can be evaluated by indicators such as turbidity and stability.
Tungsten oxide dispersion concentration
The concentration of tungsten oxide particles in the tungsten oxide dispersion is also an important technical indicator. Concentration can be expressed as the mass concentration or volume concentration of particles, and the common unit is weight percent or volume percent.
Tungsten Oxide Dispersion Stability
The stability of tungsten oxide dispersion refers to its ability to maintain a dispersed state during storage and use. Stability is affected by many factors, such as surface modifiers, ionic strength, pH, etc., and can be evaluated by observing precipitation, stratification, or particle size changes, etc.
Tungsten oxide dispersion pH value
The pH value of the tungsten oxide dispersion is also an important indicator. The pH value affects the charge state and dispersibility of the particles and can be measured with a pH indicator or a pH meter.
Tungsten Oxide Dispersion Viscosity
Viscosity is an indicator of the fluidity of tungsten oxide dispersions, which is affected by particle concentration and interparticle interaction forces. Viscosity can be measured using an instrument such as a viscometer.
Tungsten Oxide Dispersion Surface Modifier
Surface modifiers are often added to tungsten oxide dispersions to adjust the dispersion and stability of particles. The type, concentration and nature of the surface modifier is also an important technical indicator.
