Silica sol is a dispersion of nano silica particles, with a typical particle size of 3-150nm. The density of nano silica particles in silica sol is 2.2-2.3, while water has a density of 1, with a significant difference in density. However, we have observed that silica sol can remain suspended and stable for a long time. Why is this?Ordinary silica sol is a water dispersed solution of nano silica, with negative charges on the surface of particles. Therefore, there is a repulsive effect of the same charge between particles, which prevents agglomeration. This is the fundamental reason for the stability of silica sol suspension system. In addition, the thermal motion of water molecules constantly impacts nanoparticles, causing them to be in motion (Brownian motion). Therefore, silica sol with small particle size can remain suspended and stable for a long time. For example, silica ...

1. CastingDue to its excellent adhesion, low shrinkage, and relatively complete glass phase transition at high temperatures, high-purity silica sol is preferred. It is widely used as a shell bonding agent in the casting industry.2. Refractory materialsThe silicate refractory fibers mainly made of high-purity silica sol have energy-saving and high temperature resistance properties. Widely used as insulation material in thermal and industrial equipment such as furnaces and kilns. Other amorphous refractory materials using high-purity silica sol as a binder, as they do not introduce various low melting point oxides. Improved usability. And it has the advantages of high demolding strength, stable high-temperature volume, and good resistance to high-temperature thermal shock. In addition, acid resistant cement or ceramics treated with high-purity silica sol. Chemical equipment capa...
