The average particle diameter of crystals of the aluminum titanate is not less than 10 .mu.m, and not more than 20% by volume of a glass phase containing a rare earth element in an amount of 0.5 to 16% by weight when calculated in the form of an oxide is contained. Young's modulus is 50 to 2,000 kgf/mm.sup.2. A process for producing the same is also disclosed, which includes the steps of preparing a powder by mixing a material, as an Al.sub.2 O.sub.3 source material, containing not more than 96% by weight of Al.sub.2 O.sub.3 and having an average particle size of not less than 3 .mu.m, a material having an average particle diameter of not more than 3 .mu.m as a TiO.sub.2 source material, and a given rare earth element in an amount of 1.8% by weight when calculated in the form of an oxide, shaping the powder, and drying and firing the shaped body. The ceramic material has an actual break strain of not less than 6.times.10.sup.-3. The process for producing such a ceramic material includes a step of cooling the shaped body at a rate of at least not less than 500.degree. C./hr in a temperature range not less than 200.degree.

摘要： In a method for effectively producing ceramic manifolds for thermally insulating exhaust channels, an intermediate product is first formed by drain casting which includes a main ceramic pipe having a plurality of branch pipes extending therefrom whose ends are connected together by elongated connection members in the form of thin plates or bars. Thereafter, the intermediate product is fired and the ends of the branch pipes are then cut off together with the connection members. In this manner, even ceramic pipes complicated in shape readily can be produced by preventing strains and deformations which would otherwise occur during firing of the intermediate product.

摘要： This method is to mold a ceramic port liner from a ceramic material by drain casting. The slurry of the ceramic material is subjected to a pressure of 5 kgf/cm.sup.2 or higher in a mold. The method is also to mold under the condition that the mold is transformed by reducing a certain volume within the range of 0.3%-1.0% in the direction of constriction applied. According to this method, a ceramic port liner without deformation and unevenness in thickness can be obtained.
