    摘要: Novel silver halide crystals useful for both negative and positive photographic elements are produced by balanced double jet precipitation. Using that process, silver halide adds preferentially to the (111) surfaces of tetradecahedral silver bromide or iodobromide crystals to form cubic crystals which have corners containing a different silver halide from that in the lateral surfaces. In a specific embodiment, a crystal has corners composed of silver bromochloride, while the crystal substrate consists of highly photosensitive silver iodobromide.
