Körper mit Wabenstruktur und Verfahren zur Herstellung derselben

摘要

A honeycomb structural body is obtained by mixing 60 SIMILAR 80 wt% of aggregate, which does not show a transformation of crystal structures substantially up to 500 DEG C, and 20 SIMILAR 40 wt% of clay to obtain a mixture, adding phosphate as a hardening agent to the mixture in such a manner that more than 2.0 wt% of phosphoric acid exists therein with respect to 100 wt% of the mixture, adding a forming agent and a water to the mixture to obtain a formable batch, extruding the batch into a honeycomb structure to obtain a honeycomb structural formed body, drying the honeycomb structural formed body, and subjecting the honeycomb structural formed body to a heat treatment in 300 SIMILAR 500 DEG C. The thus obtained honeycomb structural body has excellent catalyst carrying property and fireproof property, which are used as a catalyst carrier for ozone dissolving, deodorizing and so on in an inexpensive manner.
