Coating of colloidal silica on glass surfaces with bbk nano silica as raw material

Electrophoretic silica-coating process on a nano-structured copper electrode.

A method for silica-coating at the nanoscale by electrophoretic deposition is presented here, using raw or grafted silica dispersions.

The Charge of Glass and Silica Surfaces

Ionization processes in aqueous solutions have long been a point of central interest to physical chemistry. Much progress has been made in recent years in understanding the charging properties of such different entities as small molecules, polyelectrolytes and various kinds of interfaces [1]. In this context, silica and silicate glass surfaces immersed in water are known to acquire a negative s...

Facile and economic method for preparation of nano-colloidal Silica with controlled size and stability

This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...
