Abstract

본 발명은 항균성 세라믹스와 그 제조방법에 관한 것으로서, 더욱 상세하게는 항균금속이온으로 담지시켜서 제조된The present invention relates to antimicrobial ceramics and a method of manufacturing the same, and more particularly, prepared by supporting with antimicrobial metal ions.

Li-Ti-Al-P-0계의 인산염계 다공질 세라믹스로 이루어진 항균성 세라믹스에 유기규소화합물을 처리하여 실리카재질을 피복하므로써, 성형품을 제조하는 경우 항균성은 저하되지 않으면서 성형품의 색강경시변화가 없는 새로운 형태의 항균성 세라믹스와 이를 제조하는 방법에 관한 것이다.By coating organosilicon compounds on silica-based antimicrobial ceramics made of Li-Ti-Al-P-0-based phosphate-based porous ceramics, when manufacturing molded products, the antimicrobial properties of the molded products are not degraded and the color change of the molded products is reduced. It relates to a new type of antimicrobial ceramics and a method of manufacturing the same.
