Lithium alumino-silicate glass ceramics

摘要: Cerium dioxide or a cerate compound is proposed as refining agent for p-eucryptite (a lithium aluminium silicate glass-ceramic material whose thermal coefficient of expansion can be adjusted to near zero by controlled substitution and devitrification). agents enable transparent β-eucryptite obtained, which useful in applications such cooker hobs also lasers. Hitherto, arsenic antimony oxides, are volatile at the temperature, have been used agents.
