<P>PROBLEM TO BE SOLVED: To solve problems that the applicability of a ceramic to be effective in many applications is limited now, the application using the antibacterial action is also restricted and it is also difficult to make a product lightweight. <P>SOLUTION: The ceramic is obtained by blending 3-10% calcium oxide, 0.1-0.5% chromium oxide, 0.05-0.2% manganese oxide, 3-9% iron oxide, 0.05-2% cobalt oxide, 0.4-2% potassium oxide, 1-6% sodium oxide and 0.4-2% magnesium oxide with one comprising 30-70% silicon oxide and 10-30% aluminum oxide wherein total of silicon oxide and aluminum oxide is ≥60% of the whole and the balance being usual impurities and making it powdery. Further tourmaline is added and blended and and titanium oxide is added and blended. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
