Verfahren zur Herstellung von keramischen Wabenstrukturen |
摘要 |
A method of producing ceramic honeycomb structures which comprises: the first step of preparing a ceramic plastic composition which comprises admixing and kneading a ceramic material with water, a polyalkylene glycol monoether and an organic binder; the second step of extruding the ceramic plastic composition into a wet green mold of a honeycomb structure having openings extending therethrough; the third step of passing a high humidity air through the openings to evaporate the substantial amount of the water in the green mold; the fourth step of passing heated air to evaporate the substantial amount of the polyalkylene glycol monoether from the green mold; and the fifth step of calcining the mold. The method is suitably applicable to the production of ceramic honeycomb structures as a catalyst structure or a catalyst carrier structure therefor which contains a material acting as an oxidation catalyst. |
