Usage areas:
Glass and Ceramics Production:
TEOS is an important precursor in the production of silica-based materials in the glass and ceramic industries. TEOS can be used to form high-purity silica films and may find particular use in thin film technologies, the semiconductor industry and the production of solar cells.
Coating Materials:
TEOS is used in the production of surface coating materials. It can be used in various coating processes, especially to strengthen or protect the surface of the substrates.
Chemical analysis:
TEOS is used in some chemical analysis methods. For example, combined silica can be used to prepare coating materials, finding use in analytical chemistry applications and materials science research.
