The binding, dispersing, sequestering, buffering, film-forming and anti-corrosion properties of silicates are well known and it is these attributes, together with their silica payload, which account for their extensive use in industry. The environmental acceptability of silicates and their non-flammability, attributable to their inorganic nature, combine to make the silicate family quite unique.
The key to the successful application of silicates is ensuring that the product characteristics are the optimum for the purpose. The performance of soluble silicates is governed by such parameters as the silica to alkali ratio, type of cation and in the case of liquors, the solids content. This, in turn, controls viscosity and specific gravity.
