Estimating the term…
Silver sodalites with cages containing anions such as oxalate, formate, halide, carbonate, sulphide etc. have silver compositions entrapped or encapsulated in the cages of a microporous sodalite lattice. The cages of the sodalite lattice have very small but very even sizes e.g. 6.6 A diameters, so that the silver compositions trapped therein are also of very small but very even sizes. The silver compositions may be sensitive to the application of light, and may be sensitive to thermal or pressure stimuli. Thus, images produced by, for example, irradiation of the materials can be of very high resolution. The silver sodalite materials are prepared by a silver ion exchange process, from synthetic sodium sodalites.
A silver sodalite material comprising a radiation senstive silver composition entrapped within the cubooctahedral cavities of the sodalite framework, the silver component thereof being reducible with accompanying alteration of the optical properties thereof, with, the sodalite cavities on irradiation, said composition comprising at least one anion selected from the group consisting of oxalate, hydroxide, azide, carbonate, bicarbonte, sulfate, sulfite, chlorate, perchlorate, acetate and formate, the anion being in charge association with the silver.
A silver sodalite material selected from the group consisting of silver oxalate sodalite, silver formato sodalite, sulfur-doped silver bromide sodalite, silver carbonate sodalite, and silver perchorate sodalite.
Silver oxalate sodalite.
A recording material sensitive to incident light radiation or to localized heating to form images of high resolution in response thereto, said recording material comprising (i) a thin layer of a light or heat sensitive silver sodalite material, said material comprising at least one anion selected from the group consisting of oxalate, hydroxide, azide, carbonate, bicarbonate, sulfate, sulfite, chlorate, perchlorate, acetate and formate, the anion being in charge association with the silver;
