Glass composition having high thermal and chemical stability |
摘要 |
Described herein are alkali-free, boroalumino silicate glasses exhibiting desirable physical and chemical properties for use as substrates in flat panel display devices, such as, active matrix liquid crystal displays (AMLCDs) and active matrix organic light emitting diode displays (AMOLEDs). In accordance with certain of its aspects, the glasses possess good dimensional stability as a function of temperature. |

1. A glass comprising in mol percent on an oxide basis:
70≦SiO2≦74.5 10.5≦Al2O3≦13.5 0≦B2O3≦2.5 3≦MgO≦7 3≦CaO≦7 0≦SrO≦4 1.5≦BaO≦6 0≦SnO2≦0.3 0≦CeO2≦0.3 0≦As2O3≦0.5 0.01≦Fe2O3≦0.08 F+Cl+Br≦0.4wherein
(SiO2+Al2O3)/(1−B2O3/100)=86.97−0.713*(RO—Al2O3)/(1−B2O3/100)±0.8where:
(i) RO=MgO+CaO+SrO +BaO, and (ii) SiO2, Al2O3, B2O3, MgO, CaO, SrO and BaO represent the mol percents of the representative oxide components. |
