SILICATE GLASS COMPOSITION AND PROCESS FOR MODIFICATION OF CERAMIC MATERIALS

摘要

The invention relates to a silicate glass composition. Said composition has a low melting point and the glass properties thereof allow compensation for the stresses between workpieces and inside a workpiece. The properties, such as colour, biological activity or mechanical stability, of a ceramic or vitreous workpiece already fired can subsequently be affected according to the invention by surface handling of said workpiece with said composition. The composition is also suitable for use as a primer for bonds between workpieces with different coefficients of thermal expansion. It is also possible to modify the ceramic at the design stage.
