| titleOfInvention | Alkali-free glass and its manufacture method |
| abstract | The present invention provides that strain point is high and meltability when being high Young's modulus and glass manufacture is excellent, the easy alkali-free glass of float forming and its manufacture method.The Young's modulus of the alkali-free glass is more than 84.5GPa, and strain point is that the mean thermal expansion coefficients at more than 680 DEG C, 50~350 DEG C is 30 × 10 ‑7 ~47 × 10 ‑7 / DEG C, represented with the quality % of oxide benchmark, contain SiO 2 55~69, Al 2 O 3 17~27, B 2 O 3 0~4, MgO 0~20, CaO 2~20, SrO 0~3, BaO 0~7, SnO 2 0.01~1, SiO 2 +Al 2 O 3 + MgO+CaO is that more than 90, MgO+CaO+SrO+BaO is 12~23, meets [SiO 2 ]×6.7+[Al 2 O 3 ]+[B 2 O 3 ]×4.4‑458≤0。 |
