Usage
Ethyl silicate (TEOS) is a colorless liquid, mainly used as heat-resistant coatings, chemical-resistant coatings, silane coupling agents, organic synthesis intermediates, and as a precursor for chemical vapor deposition (CVD)SiO2 films in the semiconductor field, etc. The melting point of ethyl silicate is -77℃, and its boiling point is 165.5℃. It is slightly soluble in water and soluble in ethanol and ether.
It is used as an insulating material in the electronics industry and also as a processing agent for optical glass and a coagulant
Used for precision casting as a binder for sand molds; The metal surface treated with ethyl silicate vapor can prevent corrosion and water. Ethyl silicate can be used to impregnate the surface of metals with silicon, and treating optical glass can increase its light transmittance. The extremely fine silica powder produced after complete hydrolysis can be used to manufacture phosphors. Ethyl silicate is the raw material of silicone oil. Ethyl silicate can also be used to manufacture heat-resistant and chemical-resistant coatings. In Japan, 90% of ethyl silicate is used as the base material for anti-corrosion coatings (zinc-rich paint).
It is mainly used in chemical-resistant coatings and heat-resistant coatings, silicone solvents and precision adhesives. After complete hydrolysis, extremely fine silicon dioxide powder is produced, which is used to make phosphors and can also be used as a chemical reagent.
Tetraethoxysilane is mainly used in optical glass, chemical-resistant coatings, heat-resistant coatings and adhesives. Modification of anti-corrosion coatings Crosslinking agent, binder, dehydrating agent; Manufacturing of catalyst skeletons and high-purity ultrafine silica
Ethyl orthosilicate is mainly used in optical glass, chemical-resistant coatings, heat-resistant coatings and adhesives. Modification of anti-corrosion coatings Crosslinking agent, binder, dehydrating agent; Manufacturing of catalyst skeletons and high-purity ultrafine silica.
Insulating materials for the electronics industry, coatings, optical glass treatment agents, coagulants, organic synthesis, solvents for preparing organosilicon
In the embedded compound that forms H+-magadiite, it will react with dodecylamine for the study of mixed metal bioactive glass. It is commonly used as a precursor in the preparation of dry gels
