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.
