Abstract
A needle-shaped ceramic body having as its base material a cordierite porous body having a high specific surface area and superior thermal shock resistance, and a needle-shaped catalyst-ceramic body are provided. The present invention relates to a needle-shaped ceramic body having as its base material a needle-shaped cordierite in which the tips thereof are rounded, a needle-shaped catalyst-ceramic body loaded with a catalyst, and a method of production of a ceramic body in which a portion of a raw material (fluoride) gasified by a reaction between raw materials is grown into a needle like shape on the metal catalyst (Fe), wherein the tips of needle-shaped particles are rounded, using a vapor-liquid-solid (VLS) reaction, in a raw material burning process. A honeycomb structure composed of the needle-shaped ceramic for supporting a catalyst is provided, in which decreases in specific surface area caused by sintering can be inhibited, and it enables early catalyst activation due to the low thermal capacity, and has low pressure loss.
