Abstract:
Provided herein is a glass composition comprising: about 72 mol % to about 77 mol % SiO 2 ; about 8 mol % to about 12 mol % Al 2 O 3 ; about 10 mol % to about 14 mol % of one or more alkali oxide R 2 O, wherein R 2 O is Li 2 O, Na 2 O, K 2 O, Rb 2 O, or Cs 2 O; one or more divalent oxide RO, wherein RO is MgO, CaO, SrO, BaO, or ZnO; and P 2 O 5 , wherein the ratio of mol % RO/(mol % R 2 O+mol % RO) is at least about 0.2. The glass composition has one or more of the following characteristics: (i) a low temperature (form 25° C. to 300° C.) coefficient thermal expansion (LTCTE) of less than 7.5 ppm/° C.; (ii) high temperature coefficient thermal expansion (HTCTE) of less than 18 ppm/° C.; (iii) liquidus viscosity of at least 200,000 poise; (iv) glass temperature of at least 1100° C. at 200,000 poise or at least 1200° C. at 35,000 poise; and (v) a fictive temperature T f  less than about 795° C.

Claim (Index 12):
The glass composition of  claim 1 , which is substantially free of K 2 O, B 2 O 3 , and/or Li 2 O.
