PROCESS FOR REDUCING THE CONTENT IN CROMOPHORE IONS IN BARIUM CHLORIDE

The process comprises a technique yielding high-purity barium carbonate for production of phosphatic laser glasses. A reactive barium chloride solution in de-mineralised water of 13.5 per cent concentration has added to it, by mixing and heating at 70-80 deg.C 12-15 g of ammonium sulphocyanide per 1...

Zusammenfassung:The process comprises a technique yielding high-purity barium carbonate for production of phosphatic laser glasses. A reactive barium chloride solution in de-mineralised water of 13.5 per cent concentration has added to it, by mixing and heating at 70-80 deg.C 12-15 g of ammonium sulphocyanide per 100 kg of BaCl2.2H20. The resulting solution then receives at boiling pt. 5ml of pyridine per 100 litres of solution with final cooling and filtration to remove the precipitate.
