Applications

The tetraalkyl orthosilicates ( also called orthosilicic acid esters) most commonly used as starting materials for sol-gel.

Polysilicic acidesters are condensation products obtained by incomplete hydrolysis or orthosilicic acid esters. They are also be used as starting materials for the sol-gel process.
