| titleOfInvention | Preparation of silver halide emulsion |
| abstract | PURPOSE:To enable exact silver ion activity to be measured even if the silver ion concn. in a silver halide emulsion is as low as about 10<-10>mol/l, by using a silver sulfide electrode as a detection control sensor of silver ions. CONSTITUTION:The silver sulfide electrode can be obtained, e.g., by adding silver nitrate into a soln. of sodium sulfide and press molding the precipitated silver sulfide. Hardly soluble silver grains of a silver halide emulsion are prepared by monitoring and controlling pH and PAg with the device widely known in the field of the photographic industry. On the other hand, silver halide includes silver bromide, silver chloride, silver iodide, etc., and preferable diameters of preparable silver halide grains are 0.1-4mum, especially, 0.2-2mum. As the typical silver halide solvents, ammonia, thioethers, compds. having a thiocarbonyl group combining with one of oxygen atoms and a nitrogen atom, etc., are enumerated. |
