A thermoplastic ceramic molding composition comprised of about 40 to 70 volume percent of a binder, consisting essentially of an organic acid containing from 12 to 26 carbon atoms per molecule and a polyisobutylene polymer having a molecular weight between about 8,700 and 135,000, and about 30 to 60 volume percent of a ceramic powder is disclosed. The molding composition can be thermoplastically extruded into elongate ceramic bodies that can be uniformly elongated many times the original length of the ceramic body to form, for example, very fine diameter fibers or filaments suitable for sintering into a polycrystalline ceramic fiber or filament having a very fine diameter. |
