A method for controlling microbes (not including microbes located in or on the human body) is disclosed, wherein the method comprises the step of contacting the microbe with functional transition metal silicate characterized in that the said transition metal silicate is selected from the group comprising: a. Cupric silicates having silica to copper ratio in the range of 1:0.34 to 1:5.15; b. Zinc silicates having silica to zinc ratio in the range of 1: 2 to 1: 12; c. Silver silicates having silica to silver ratio in the range of 1: 15 to 1 : 19.5; d. Manganese silicates having silica to manganese ratio in the range of 1 : 1 to 1 : 1.9; and e. Zirconium silicates having silica to zirconium ratio in the range of 1 : 0.77 to 1 : 2.9, the said transition metal silicates are prepared by the process comprising the steps of: (i) adding a transitional metal salt solution to a soluble alkali silicate solution to form a mixture; (ii) forming a precipitate of a transitional metal silicate, and (iii)washing and drying the precipitate thus formed to obtain the transitional metal silicate, wherein in said step (i), the ratio between the transitional metal salt solution to the alkali silicate solution is varied, the temperature at which the solutions are mixed is varied between 20 to 90 Deg C, and the pH value of the medium is varied between about 2 to about 11. The disclosure also relates to a functional transition metal silicate (FTMS) effective as a decontaminant, a disinfectant, a detoxificant, a protectant, a microbicide or combination thereof, comprising a ratio of transition metal to silica in the transition metal silicate in a predetermined range and a structural composition for said effectiveness, said FTMS being capable of being immobilized on a suitable materials or incorporating into resins and / or coating along with resins on suitable materials.
