用于发光装置的玻璃，玻璃覆盖材料和发光装置

Glass, glass covering material for light-emitting device, and light-emitting device
Abstract:
Glass is provided which is capable of covering at a covering treatment temperature of at most 400° C. and which has a low thermal expansion coefficient and excellent weather resistance. Glass comprising, as represented by mol % based on oxides, from 29% to 33% of P2O5, from 43% to 58% of SnO, from 11% to 25% of ZnO, from 0.1% to 2% of Ga2O3, from 0.5% to 5% of CaO, and from 0% to 1% of SrO, provided that the sum X of ZnO, Ga2O3 and CaO is within a range of from 13% to 27%, as represented by mol % based on oxides.
