ABSTRACT:
Impervious, unglazed, sintered ceramic products of primarily cordierite crystal phase, exhibiting low coefficients of thermal expansion and having analytical molar composition of about 1.7-2.4 RO . 1.9-2.4 Al.sub.2 O.sub.3 . 4.5-5.2 SiO.sub.2, are formed of mineral batch compositions that are: (a) wholly raw ceramic material wherein RO comprises about 55-95 mole % MnO and 5-45% MgO, or (b) at least about 50 wt.% prereacted cordierite material and the balance thereof raw ceramic material, and wherein RO comprises about 5-40 mole % MnO and 60-95 mole % MgO.
