A glass body comprising an alkali-containing glass substrate and a silicon oxide layer formed on its surface for preventing diffusion of alkali metal ions from the glass substrate, characterized in that said silicon oxide layer contains from 0,01 to 25 molar % hydrogen bonded to silicon.
Claim 2
Dependent Claim
46 words
A glass body comprising an alkali-containing glass substrate and a silicon oxide layer formed on its surface for preventing diffusion of alkali metal ions from the glass substrate, characterized in that said silicon oxide layer contains from 0,01 to 25 molar % hydrogen bonded to silicon.
Claim 3
Dependent Claim
28 words
The glass body according to Claim 1, wherein the content of the hydrogen bonded to silicon in the silicon oxide layer is from 0,1 to 22 molar %.
