Abstract

1,247,697. Preparing silver halides and cadmium carbonate. FUJI SHASHIN FILM K.K. 22 Oct., 1968 [30 Jan., 1968; 23 Oct., 1968], No. 50145/68. Heading C1A. [Also in Divisions B1 and G2] A process for preparing crystals of a sparingly soluble inorganic salt by double decomposition of two or more inorganic salts, comprises adding simultaneously aqueous solutions of the inorganic salts to a dispersing medium with stirring, and increasing the rate of addition of the aqueous solutions of the inorganic salts to be reacted at a rate which increases with the growing rate of the surface areas of the growng crystals of the sparingly soluble inorganic salt thus formed. In the examples silver nitrate and potassium bromide are used to prepare uniform silver bromide crystals of grain size 0À4 microns in a gelatine solution and also sodium carbonate and cadmium chloride solutions are mixed in gelatine so as to obtain cadmium carbonate crystals of grain size 6 microns. Silver chloride, iodidobromide and iodochloride can also be prepared by the method.
