In tungsten oxide dispersions, agglomeration refers to the phenomenon that particles gather to form clusters or accumulations. This agglomeration behavior may lead to a decrease in the uniform dispersion of the particles, affecting the performance and stability of the dispersion. The main reasons for the agglomeration between tungsten oxide particles are as follows:
Van der Waals force of tungsten oxide particles
There is a van der Waals force attraction on the particle surface, and when the van der Waals force between particles is large, agglomeration is easy to occur.
Surface Charge of Tungsten Oxide Particles
Particle surfaces are charged, which can lead to particle aggregation when the electrostatic repulsion between particles is insufficient to overcome other forces.
Solvent properties of tungsten oxide dispersion
The nature of the solvent has an effect on particle dispersion. Some solvents may not be conducive to the dispersion of particles, resulting in agglomeration.
Environmental Factors of Tungsten Oxide Dispersion
Environmental factors such as temperature, pH value, and salt concentration can also affect the dispersion state of particles. Changing environmental conditions may cause particle agglomeration.
