Sol solution for producing glass coatings for electrically conductive materials that can be used in anodic bonding

摘要

Disclosed is a sol solution and a method for producing this sol solution, which serves as a coating agent for producing glass coatings for electrically conductive materials that can be used in anodic bonding. The sol solution is a mix of an organosol consisting of SiO₂ dissolved in at least one n-alkanol or a mixture of a multiplicity of n-alkanols, a tetraethyl orthosilicate (TEOS) and/or a triethoxy silane or a trimethoxy silane as well as an acid or a base and water and the mixture being partially polymerized. The sol mixture is distinguished in that the mix contains an alkali alcoholate.
