A process for preparing ceramic moldings containing no organic matter with retention of their original shapes which comprises mixing 100 parts by weight of ceramic powders and/or fibers, 0.1 to 50 parts by weight of papermaking organic fibers and/or wet-end additives and 3 to 200 parts by weight of

A process for preparing ceramic moldings containing no organic matter with retention of their original shapes which comprises mixing 100 parts by weight of ceramic powders and/or fibers, 0.1 to 50 parts by weight of papermaking organic fibers and/or wet-end additives and 3 to 200 parts by weight of mountain leather, molding the resulting mixture to obtain an unburned molding having enough mechanical strength to withstand molding processings and, subjecting the unburned molding to burning treatment.

A process for preparing a ceramic molding comprising the steps of: (1) dispersing in water a composition comprising 100 parts by weight of a ceramic component, 2 to 50 parts by weight of cellulose pulp and 3 to 200 parts by weight of mountain leather, said ceramic component comprising 100 to 20 part

A process for preparing a ceramic molding comprising the steps of: (1) dispersing in water a composition comprising 100 parts by weight of a ceramic component, 2 to 50 parts by weight of cellulose pulp and 3 to 200 parts by weight of mountain leather, said ceramic component comprising 100 to 20 parts by weight of ceramic fiber and 0 to 80 parts by weight of ceramic powder; (2) forming a paper-like sheet from the resulting dispersion using a paper making machine; (3) forming a ceramic molding by folding said paper-like sheet; and (4) burning said ceramic molding at a temperature between 250°to 700°C. to burn-off said cellulose pulp, resulting in a ceramic molding which retains a pre-burned shape.
