| 摘要 |
This invention is directed to a glass composition comprising, in mole %, 2-7% M, wherein M is selected from an oxide of the group of alkali elements and mixtures thereof, 46-66% SiO2, 4-9% Al2O3, 5-9% B2O3, 0.5-7% MgO, 1-6% SrO and 11-21% CaO wherein the molar ratio of SrO/(MgO + CaO) is between 0.06 and 0.45. The invention is further directed to the use of the composition in low temperature co-fired ceramic tapes. |
