Title:
LITHIUM OXIDE-ALUMINA-SILICA-BASED CRYSTALLINE GLASS AND CRYSTALLIZED GLASS, AND METHOD OF MANUFACTURING THE CRYSTALLINE GLASS AND THE CRYSTALLIZED GLASS
Document Type and Number:
Japanese Patent JP2004075441
Kind Code:
A
Abstract:
To provide Li2O-Al2O3-SiO2-based crystalline glass which melts and can be formed at a low temperature, transparent crystallized glass and opaque crystallized glass, which have excellent thermal characteristics and mechanical strength, and methods of manufacturing the crystalline glass, the transparent crystallized glass and the opaque crystallized glass.
The Li2O-Al2O3-SiO2-based crystalline glass contains at least Li2O, Al2O3 and SiO2, and further contains P2O5 in an amount of 0.5-4.0 wt.% or F in an amount of 1.0-3.0 wt.%. The crystallized glass is obtained by forming nuclei in the crystalline glass and crystallizing the glass. The methods of manufacturing the crystalline glass and the crystallized glass are also provided.
