Abstract
A surface-modified glass that includes glass containing at least one multivalent metal ion; and a silicate film on a surface of the glass, the silicate film containing a multivalent metal ion in common with that of the glass.
Claims19
A surface-modified glass comprising:
- glass containing at least one multivalent metal ion;
- and
- a silicate film on a surface of the glass, the silicate film containing a multivalent metal ion in common with that of the glass.
An electronic component comprising:
- a ceramic element body having an outer surface;
- an electrode layer on at least a portion of the outer surface of the ceramic element body;
- glass on a surface of at least one of the ceramic element body and the electrode layer, wherein the glass contains at least one multivalent metal ion;
- and
- a silicate film on a surface of the glass, wherein the silicate film contains a multivalent metal ion in common with that of the glass.
2 more elements
A method for forming a silicate film comprising:
- applying a coating agent containing alkali metal silicate to a surface of glass that contains at least one multivalent metal ion;
- and
- forming a silicate film containing a multivalent metal ion in common with that of the glass on the surface of the glass through dissolution of the at least one multivalent metal ion in the glass to the surface of the glass.
