Title:
GLASS CRYSTALLINE MATERIAL AND METHOD FOR OBTENTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1984/000536
Kind Code:
A1
Abstract:
The glass crystalline material bears a granitoid semblance and in general consists of beta-wollastonite crystals, being in the shape of spherulites, at the following ratio in % by mass: SiO2 55.0-60.0, Al2O3 6.0-9.0, CaO 17.0-25.0, MgO 3.0-10.0, K2O 5.0-7.0, Na2O 1.0-2.0, F- 1.0-2.5; The method for obtaining the material provides for moulding the glass from a melt, which melt contains SiO2, Al2O3, CaO, MgO, Na2O, K2O, F-, its cooling down to the temperature which is 30-50oC lower than the temperature of the glass-transition, and performing the thermal treatment of the glass untill achieving its transformation into said glass crystalline material.
