PROBLEM TO BE SOLVED: To obtain a ceramic powder material generating active oxygen by exciting effectively water molecules and excellent in deodorizing and antimicrobicidal properties by including silicon oxide and aluminum as a main component, and furthermore including transition element oxides consisting of cobalt oxide, iron oxide, manganese oxide and titan oxide and zinc oxide in the equal compositional rate, followed by burning the mixture uniformly. SOLUTION: This method comprises: (A) preparing a material of silicon oxide and aluminum oxide of 25 to 50 wt.% the silicon oxide, adding to the material 180 to 240 wt.% of water as a binding material based the material and subjecting the resultant mixture to spray burning so as to obtain a silicon oxide-aluminum oxide powder material; (B) adding water in the same ratio as the above to cobalt oxide and iron oxide mixed in an equal ratio and subjecting the resultant mixture to spray burning so as to obtain a cobalt oxide-iron oxide powder material; (C) preparing manganese oxide and titan oxide of 20 to 40 wt.% the manganese oxide, and adding water in the same ratio as the above thereto, followed by subjecting it to spray burning so as to obtain a manganese oxide-titan oxide powder material; and subjecting the mixture of 60 to 80 wt.% of component A, 15 to 30 wt.% of components B and C, and 5 to 10 wt.% of zinc oxide to spray burning. |
