Abstract:
A glass composition for producing chemically strengthened alkali-aluminosilicate glass and a method for manufacturing the chemically strengthened alkali-aluminosilicate glass. The chemically strengthened alkali-aluminosilicate glass is suitable for use as high-strength cover glass for touch displays, solar cell cover glass and laminated safety glass, and is produced in a shorter amount of time.

Claim (Index 24):
A method for producing a chemically strengthened alkali-aluminosilicate glass, comprising:\n mixing and melting glass raw material components to form a homogenous glass melt composition comprising in mol % on an oxide basis: from about 63.0% to about 68.0% of SiO 2 ; from about 12.0% to about 16.0% of Al 2 O 3 ; from about 10.0% to about 15.0% of Na 2 O; from about 2.0% to about 6.0% of B 2 O 3 ; from about 0% to about 6.0% of K 2 O; from about 0% to about 3.0% of MgO; and from about 0% to about 1.5% of CaO; wherein 28% is <Al 2 O 3 +B 2 O 3 +Na 2 O<33%; wherein (B 2 O 3 +Na 2 O+K 2 O)/Al 2 O 3  is \u22651; and wherein (B 2 O 3 +CaO)/MgO is \u22651; shaping the glass using a method selected from the overflow down-draw method, the floating method and combinations thereof; annealing the glass; and chemically strengthening the glass by ion exchange at a temperature of from about 390\u00b0 C. to about 450\u00b0 C. for about 2 hours to about 6 hours.
