Application

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.
