METHOD FOR MANUFACTURING TEMPERED GLASS

摘要

PROBLEM TO BE SOLVED: To provide a high-strength tempered glass material by a method for manufacturing the tempered glass of a glass material which is difficult to be tempered by a tempering process by air cooling which requires the thickness of the glass material to soften the surface of the glass material and a chemical tempering process which has a restriction in the composition of the glass material for an ion exchanging. SOLUTION: The glass material is tempered by condensing ultra-short pulse lasers and irradiating the surface of the glass material or the interior of the glass material with the condensed laser to form heterogeneous phases to a dotty, linear or reticulate form.
