CRYSTALLIZED GLASS

摘要

PROBLEM TO BE SOLVED: To provide crystallized glass having an improved thermally-softened processability while maintaining thermal shock resistance.

SOLUTION: The crystallized glass contains Li2O-Al2O3-SiO2-based crystal in an amount of 20-70 wt.%. In the crystallized glass, the difference between the average coefficients of linear thermal expansion of matrix glass and the Li2O-Al2O3-SiO2-based crystal is≥35×10-7/K in a temperature range of 30-380°C.
