SOL SOLUTION FOR PRODUCING GLASS COATINGS FOR ELECTRICALLY CONDUCTIVE MATERIALS THAT CAN BE USED IN ANODIC BONDING

摘要

The invention relates to a sol solution and to a method for producing said sol solution, the latter acting as a coating agent for producing glass layers on electrically conductive materials that can be used in anodic bonding. The sol solution is a mixture of an organosol, consisting of SiO2, dissolved in at least one n-alkanol, or in a mixture of several n-alkanols, a tetraethyl orthosilicate (TEOS) and/or a triethoxy or trimethoxy silane, in addition to an acid or base and the mixture is at least partially polymerised. The sol solution is characterised in that the mixture contains an alkali alcoxide.
