PROCESS FOR THE PREPARATION OF DOUBLE RUBIDIUM-MANGANESE (III) DIPHOSPHATE

摘要

A process for the preparation of double rubidium-manganese (III) diphosphate comprises the use of mechanical mixture of polycrystalline substances. The direct oxidation of manganese (III) metaphosphate by rubidium nitrate is carried out, taken in equimole ratio and further baking of their mechanical mixture to constant mass with the preparation of polycrystalline double rubidium-manganese (III) diphosphate in solid polycrystalline state.
