초록

A crystalline glass-ceramic article composed of a cordierite phase of cordierite crystals or aggregates of near-parallel crystallites, having a formula of either Mg.sub.2 Al.sub.4 Si.sub.5 O.sub.18 or A.sub.x B.sub.y Mg.sub.2 Al.sub.4+x+2y Si.sub.5-x-2y O.sub.18. With the first formula, the average size of the cordierite crystals or aggregates is less than 70 micrometers, and the mean coefficient of thermal expansion from 22.degree. C. to 800.degree. C. (CTE) is less than 9.times.10.sup.-7 /.degree. C. With the second formula, A is either sodium or potas...
