Industrial Uses

1. Performance Chemicals

  • Silica Production: Ethyl silicate is a key ingredient in producing silica (SiO2). It's hydrolyzed and condensed, forming silica colloids or gels. These silica structures can be tailored for specific applications by controlling the hydrolysis and condensation process.
  • Refractories and Ceramics: Ethyl silicate acts as a binder, adhering refractory materials into ceramic shapes. This results in materials with high heat resistance and resistance to corrosive environments. 
  • Corrosion-Resistant Coatings: It's used in combination with zinc dust to create coatings that protect surfaces from corrosion. 
  • Semiconductors: In the electronics industry, ethyl silicate is employed in the fabrication of integrated circuits, where it forms electrically insulating layers of silica glass. 
  • Precision Casting: It's used as a binder for sand molds in the precision casting process.
