A glass frit with constant composition of aSiO2-bB2O3-cAl2O3-dLi2O-eMnO2 for low temperature sintering is provided to prevent gelation and to improve acid resistance, moisture resistance and electric properties of sintered bodies after calcination by comprising SiO2, B2O3, Al2O3, Li2O and MnO2 with specific relative compositions thereof. The glass frit comprises constitutional compounds satisfying an equation of: aSiO2-bB2O3-cAl2O3-dLi2O-eMnO2 wherein a+b+c+d+e=100 and a ranges from 44 to 57mol%, b ranges from 10 to 19mol%, c ranges from 0.5 to 2.0mol%, d ranges from 30 to 37mol%, e ranges from 0 to 1.0mol%. Ratio of SiO2 to B2O3 satisfies that a/b ranges from 2.3 to 5.7. LTCC(low temperature co-fired ceramic) comprises 70 to 90wt.% of ceramic powder and 10 to 30wt.% of the glass frit. The ceramic powder is selected from MgTiO3, SrTiO3, CaTiO3, MgSiO4, BaTi4O9, Al2O3, TiO2, SiO2, (Mg,Ti)2(BO4)O, ZrO2 and combination thereof. |
