Inorganic composition for low temperature firing |
摘要 |
An inorganic composition for low temperature firing comprising about 15 to 40 weight % of glass powder and about 60 to 85 weight % of cordierite, is disclosed. The glass powder is composed of about 20 to 60 weight % of SiO2, about 30 to 50 weight % of B2O3, about 5 to 30 weight % of MgO, 0 to about 15 weight % of Al2O3, and about 1 to 5 weight % of R2O (R is alkali metal). The inorganic composition is capable of being fired at a relatively low temperature, and has a low thermal expansion coefficient and permittivity, as well as high mechanical strength. |
