摘要： There is provided a process for obtaining a cordierite honeycomb structural body with thin cell walls and no molding defects such as cell breakage or the like. Cell breakage is prevented by limiting the maximum particle size of the cordierite starting material powder to no greater than 85% of the slit width of the extrusion molding die so that the starting material particles will not clog inside the slits or the introduction port of the slits. As one cordierite starting material, talc with a mean particle size of 5 &mgr;m or greater is used to give a honeycomb structural body with a void volume of greater than 30%, for production of a honeycomb structural body, with good moldability, having a small thickness and a low heat capacity. It is preferred to add to the starting material at least a lubricant/humectant, a binder and/or a mixture of a water-soluble polyhydric alcohol derivative and a polyhydric alcohol.

摘要： A reinforcing layer 4 of nearly a cylindrical shape is formed along the outer circumferential portion of a ceramic honeycomb structure which comprises a cylindrical outer circumferential skin layer 1 and cell walls 2, the reinforcing layer 4 being formed at a position maintaining a one-cell pitch from the outer circumferential skin layer 1 and extending from one end surface of the ceramic honeycomb structure toward the other end surface thereof. The reinforcing layer 4 is integrally formed, of the same material, with the outer circumferential skin layer 1 and the cell walls 2 to reinforce the strength in the circumferential direction. This makes it possible to decrease the thickness of the cell walls 2 to not larger than 100 &mgr;m yet maintaining moldability and resistance to thermal shock.

摘要： A cordierite honeycomb body is produced by forming a cordierite material including kaoline into a honeycomb shape and sintering it. The kaoline included in the cordierite material is at least partly composed of kaolinite having a Hinckley crystallinity index of 0.5 or more thereby having a less amorphous phase portion in a kaolinite particle. Therefore, when the cordierite material is sintered, the number of micropores generated in the cordierite is decreased due to the less amorphous phase portion in the kaolinite particles. As a result, density of the cordierite is increased without increasing a C.T.E. thereof. Thus, the cordierite honeycomb body has sufficient strength even when thickness of a cell wall thereof is decreased.
摘要翻译：通过将包含高岭土的堇青石材料形成为蜂窝状并烧结来制造堇青石蜂窝体。包含在堇青石材料中的高岭土至少部分地由Hinckley结晶度指数为0.5或更高的高岭石组成，从而在高岭石颗粒中具有较少的无定形相部分。因此，当堇青石材料烧结时，由于高岭石颗粒中的非晶相部分较少，在堇青石中产生的微孔数量减少。结果，堇青石的密度增加而不增加C.T.E. 其中。因此，即使其细胞壁的厚度减小，堇青石蜂窝体也具有足够的强度。
