ABSTRACT:
Foamable particulate cement is capable of forming sintered cordierite foamed ceramic masses. It consists essentially, by weight, of 1-40% cordierite grog, 99-60% ceramic base material and foaming agent, such as SiC. The ceramic base material is raw ceramic material that has an analytical molar composition consisting essentially of about 1.7-2.4 MO . 1.2-2.4 Al.sub.2 O.sub.3 . 4.5-5.4 SiO.sub.2 wherein MO comprises about 0-55 mole % MgO and at least 45 mole % MnO. The grog is ceramic material that has been previously fired and comminuted, and that has an analytical molar composition consisting essentially of about 1.7-2.4 RO . 1.9-2.4 Al.sub.2 O.sub.3 . 4.5-5.2 SiO.sub.2 wherein RO comprises MnO in an amount of 0 mole % up to a mole % that is about 20 mole % lower than the mole % of MO that is MnO and the balance is substantially MgO.
