일반 설명

SMS is a silicon source for silica materials and can be used as a chemical intermediate for silica gel catalysts.

애플리케이션

Reactant for:
  • Hydrothermal preparation of thorium uranium silicate (Th1-xUxSiO4) uranothorite solid solutions
  • Fabrication of dense NaA zeolite coatings
  • Reactant for preparation of tungsten modified silica as catalyst for liquid phase oxidation of styrene
Sodium metasilicate (SMS) has been used in the preparation of polypyrrole/sodium metasilicate (PPy/Na2SiO3) and polythiophene/sodium metasilicate (PT/Na2SiO3) composites, novel high dielectric constant materials for use in power electronic systems.

SMS can also be used:
  • To prepare NaZnSiO3OH, a novel chiral framework material which has potential application in ion exchange, adsorption and catalysis.
  • As a low-cost alternative to tetraethyl orthosilicate (TEOS) to synthesize highly ordered mesoporous silicas.
  • To prepare geopolymer concrete.
