Abstract: An improvement in tabular grain manufacture is provided wherein large tabular grains can be prepared in less time and with a narrower size distribution than available in the art. The improved process includes the steps of:a) forming a nucleation solution by adding aqueous soluble silver salt to a vessel containing 0.08 to 0.25 molar aqueous soluble halide salt in an aqueous medium;b) adding a solution of ammoniacal base to said nucleation solution when 0.30 to 9.0% of said soluble silver salt has been added;c) optionally ripening said nucleation solution for up to 60 minutes;d) adding said soluble silver salt to said nucleation solution preferrably at an increasing rate to obtain growth pBr of 1.3 to 2.3;e) adding said soluble silver salt and said soluble halide salt to grow said tabular grains.
