Abstract
Production of solid, hollow and spheroidic material for use as a carrier supporting motor exhaust gas decontamination catalysts. To this end, spheroidal particles of material being oxidizable and/or low melting and/or soluble in organic solvents are placed on to a pelletizing table. Ceramic pulverulent material is distributed thereover and a aqueous cellulose ether solution is simultaneously sprayed thereonto to cause deposition of the ceramic material on the particles. The resulting pellets are dried at 20.degree. - 95.degree. C and freed from material being oxidizable and/or low melting and/or soluble in organic solvents, and finally calcined at 1000.degree. - 1500.degree. C.
