Production of silver sulfate grains using inorganic additives |
| abstract |
An aqueous precipitation process for the preparation of particles comprising primarily silver sulfate, comprising reacting an aqueous soluble silver salt and an aqueous soluble source of inorganic sulfate ion in an agitated precipitation reactor vessel and precipitating particles comprising primarily silver sulfate, wherein the reaction and precipitation are performed in the presence of an aqueous soluble inorganic additive compound containing a cation capable of forming a sulfate salt that is less soluble than silver sulfate or a halide anion or an oxyanion capable of forming a silver salt that is less soluble than silver sulfate, the amount of additive being a minor molar percentage, relative to the molar amount of silver sulfate precipitated, and effective to result in precipitation of particles comprising primarily silver sulfate having a mean grain-size of less than 70 micrometers. |
