| titleOfInvention | Alkali-free glass |
| abstract | That the present invention relates to shrinking percentages is low, the mean thermal expansion coefficients at 50 DEG C~350 DEG C are small, is easy to the alkali-free glass of float forming.In particular it relates to a kind of alkali-free glass, the shrinking percentage C1 of the alkali-free glass is 5ppm or less, shrinking percentage C2 is 40ppm hereinafter, in terms of the quality % of oxide benchmark, and the alkali-free glass contains SiO 2 64~72, Al 2 O 3 17~22, MgO 1~8, CaO 4~15.5, and 0.20≤MgO/ (MgO+CaO)≤0.41. |
