Patent number: 5244667Abstract: The present invention provides a novel antimicrobial composition and a process for preparing the composition which composition is useful as antimicrobial and/or bactericidal material. The antimicrobial composition of the invention comprises silica gel and an antimicrobial coat of aluminosilicate on the surface of the silica gel, said composition having a pore volume of at least 0.3 cm.sup.3 /g and a specific surface area of at least 100 m.sup.2 /g. The aluminosilicate coat consists of either partial or complete substitution of ion-exchangeable metal ion (M) in aluminosilicate solid particles represented by the formulaxM.sub.2/n O.Al.sub.2 O.sub.3.ySiO.sub.2.zH.sub.2 O,wherein x and y represent the numbers of molecules of the metal oxide and silicon dioxide, respectively, M is an ion-exchangeable metal, n is the atomic valence of M, and z is the number of molecules of water.Type: GrantFiled: February 28, 1991Date of Patent: September 14, 1993Assignees: Hagiwara Research Corp., Japan Electronic Materials CorporationInventors: Zenji Hagiwara, Masao Okubo
