Sodium Silicates

Sodium silicate is the generic name for a series of compounds derived from soluble sodium silicate glasses. They are water solutions of sodium oxide (Na2O) and silicon dioxide (SiO2) combined in various ratios. Varying the proportions of SiO2 to Na2O and the solids content results in solutions with differing properties that have many diversified industrial applications.

Indo Chemica Lestari have standard commercial grades of liquid sodium silicates range in weight ratio of SiO2 to Na2O from 2.0 to 3.3. In addition to liquid sodium silicates.

SiO2 to Na2O from 2.0 to 3.3

Sodium silicate glass is made by fusing high purity silica sand and soda ash in open hearth furnaces at 1300 oC/2400 oF. The molten glass is cooled, fractured, and charged into vessels where it is dissolved under pressure by hot water and steam. The various grades of liquid sodium silicate are produced by varying the alkali/silica ratio and the solids content.

The glass briquest plants are located at Samarinda, Kalimantan Timur and are within convenient shipping distances of all major industrial areas.
