SODIUM METASILICATE PENTAHYDRATE Usage And Synthesis

Chemical Properties

White solid

Uses

Sodium Metasilicate Pentahydrate is used in method for preparing cement accelerator containing Aluminum Sulfate.

Uses

Sodium metasilicate pentahydrate can be used:

• As a silicate electrolyte in plasma electrolytic oxidation (PEO) coating.
• For the synthesis of sintered mullite ceramics (3Al₂O₃·2SiO₂) by the co-precipitation method.
• As a source of silica for the synthesis of silica-zirconia composites for the chromatographic applications.
• For the synthesis of photo-Fenton catalyst, nontronite, for the degradation of Rhodamine B.
• As a starting material for the synthesis of zeolite NaA layers on α-Al₂O₃ supports.

Application

Sodium metasilicate pentahydrate can be used as a fireproofing compound; laundry, dairy, metal and floor cleaning products; paper deinking; carbonated beverage bottle cleaning; insecticides, fungicides and antimicrobial compounds; chemical intermediates for silica gel catalysts; additives for soaps and synthetic detergents; bases and bleaching aids for tableware and laundry detergent formulations.
