The limits of purification of the said solutions from isomorphic admixtures (including potassium and rubidium) were estimated. Three sample parties of 1.6 kg of CsI salt were obtained after 25, 30 and 35 cycles of LTMC and experimental samples of CsI(Tl) crystals were grown from the each party of the charge. The scintillation parameters of the single crystal samples obtained from technogenic charge purified by the multiple LTMC are practically coincident with those for the crystals grown from the commercial extra pure salt. The practical limit of CsI purifications from K and Rb admixtures using multiple LTMC methods is ca. 10-5 mas.%. Product Description popup.authors popup.nrat_date 2020-04-02 Close
