CERAMICS FOR STERILIZATION, METHOD OF PRODUCTION THEREOF AND STERILIZATION METHOD USING THE CERAMICS

摘要

Ceramics for sterilization having an excellent sterilization performance and not emitting substances harmful to the health of animals and plants, a method of producing the ceramics, and a sterilization method using the ceramics. The method of producing the ceramics for sterilization comprising the steps of mixing zeolite and shells in a weight ratio of 90:10 to 50:50 and pulverizing the mixture to a mean particle size of not greater than 200 mu m, or mixing zeolite and shells each pulverized in advance to a mean particle size of not greater than 200 mu m in a weight ratio of 90:10 to 50:50 to form mixed powder, molding the mixed powder, heating step-wise the resulting molded article to 100 to 300 DEG and then to 400 to 650 DEG C, and sintering the heated molded article at 700 to 1,050 DEG C. When immersed in a solution in which bacteria exist, the ceramics for sterilization exhibit the sterilization action to the bacteria.
