摘要: Disclosed are alkali-free glasses having a liquidus viscosity of greater than or equal to about 90,000 poises, said glass comprising SiO 2 , Al O 3 B MgO, CaO, and SrO such that, in mole percent on an oxide basis: 64≦SiO ≦68.2; 11≦Al ≦13.5; 5≦B ≦9; 2≦MgO≦9; 3≦CaO≦9; 1≦SrO≦5. The can be used make display substrates, as thin film transistor (TFT) substrates for use active matrix liquid crystal devices (AMLCDs) other flat panel devices.
