According to different production methods and particle sizes, silica can be divided into precipitation method and gas phase method. However, there is not much difference in the application field, just depending on the requirements.

One of the important high-tech ultra-fine inorganic new materials. Because of its small particle size, it has large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, heat resistance, resistance and other special properties. It has excellent stability, reinforcement, thickening and thixotropy, and has unique characteristics in many disciplines and fields

◇ As a thixotropic agent and thickener of liquid, it can prevent sedimentation and sagging;

◇ Improve the suspension and dispersion of pigment fillers in the liquid system;

◇ Used as dispersing and grinding aids;

◇ Improve the corrosion resistance of the coating;

◇ Improve powder fluidity and storage stability;

◇ Improve the charging capacity and charging stability of the powder;

◇ Improve water resistance;

◇ Improve scratch resistance of paint film;

◇ Improve color brightness;

◇ Special effect of fixation;

◇ Improve the physical and mechanical properties of the paint film;

◇ Improve the adhesion and flexibility of the paint film;

◇ Improve the viscoelasticity of rubber and elastomer and strengthen them;

◇ Defoaming effect of defoamer;

◇ Improve the surface hardness and scratch resistance of the coating;

◇ Prevent adhesion of membrane and elastomer;

◇ As adsorbent and carrier;

◇ Used for inkjet printing coating;

◇ As a filling material for dental materials;

◇ As a catalyst carrier, it has remarkable heat insulation performance, and is used for low and high temperature heat insulation.
