摘要： A silver ion sequester and release agent is described which comprises a silver ion exchangeable material of the formula: M(H1−x−yAgxM′yPO4)2.nH2O; where M is Zr, Ti, Sn, Ge or Hf or any combination thereof; M′ is an Alkali or alkaline earth metal; x is a number from 0.10 to 0.80; y is a number from 0.15 to 0.85; (x+y) is a number from 0.25 to 0.95; and n is a rational number between 0 and 10. Processes for preparing such silver ion sequester and release agent material are also described comprising combining in an aqueous medium a crystalline or amorphous metal hydrogen phosphate ion exchange host material of the formula M(HPO4)2.nH2O with less than 2 molar equivalents of silver ions relative to the amount of ion exchange host material such that silver ions are exchanged for protons in the host material, and adding a base compound to the aqueous medium to achieve a pH of at least 4.4 and sequester at least 95% of the combined silver ions into the host material. Further described are photographic elements comprising a support bearing one or more hydrophilic colloid layers including at least one photographic silver halide emulsion layer, wherein one or more layers contain such a silver ion sequester and release agent which sequesters silver ions prior to photographic processing and releases silver ions upon exposure to photographic processing solutions.

摘要： A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a calcium alkali which may then be reacted with the phosphoric acid to produce dicalcium phosphate. Also, a method of producing monocalcium phosphate from calcium phosphate includes reacting the calcium phosphate with sulphuric acid to produce monocalcium phosphate. The monocalcium phosphate may be further processed to remove fluorine contamination and to produce fluorine-free dicalcium phosphate or dicalcium phosphate dihydrate.
