A novel silver-containing tobermorite usable in place of silver-, copper- or zing-incorporating zeolites and having ethylene-adsorbing ability and antibacterial properties. Stated more particularly, a silver-containing tobermorite having a composition of [Ca5-y/2Agy+zMx-z(Si?-xAlxO1?H2) 4H2O, 0 ? X ? 1, 0.001 ? Y ? 2, 0 ? Z ? 0.1, M is a monovalent cation] and prepared from a tobermorite [Ca5Mx(Si?-xAlxO1?H2) 4H2O, O ? X ? 1, M is as defined above] by exchanging Ca2+, or Ca2+ and a monovalent cation which are interlayer ions of the tobermorite for silver ion. The silver-containing tobermorite is excellent in heat resistance, water resistance and mechanical strength, and also outstanding in ethylene-adsorbing ability and antibacterial properties. |
