Synthesis and Stabilization of Crystal Hydrate Modification SrSO4•0.5H2O

N. N. Bushuev et al.

Summary: A method has been developed to synthesize the metastable trigonal modification SrSO4·0.5H(2)O, and its structure can be stabilized by isovalent or aliovalent substitution. The compound K0.25La0.25Sr0.5(SO4)·0.5H(2)O has been synthesized as an example of the stabilized SrSO4·0.5H(2)O modification.

KLa(SO4)2-SrSO4 System at Temperatures above 600°C

N. N. Bushuev et al.

Summary: The KLa(SO4)(2)-SrSO4 system was studied at temperatures above 600 degrees C by X-ray diffraction and thermogravimetric analysis. The results show the presence of solid solutions based on the orthorhombic phase beta-SrSO4, covering a broad range of compositions (0-70 mol % KLa(SO4)(2)). The unit-cell parameters and volume of the solid solutions were determined and found to increase systematically with composition. The formation of the solid solutions is due to heterovalent substitution of potassium and lanthanum ions for strontium ions, and they decompose above 950 degrees C to produce oxides and sulfates.

Investigation of the KLa(SO4)2•H2O-SrSO4•0.5H2O System

N. N. Bushuev et al.

Summary: The KLa(SO4)(2)·H2O-SrSO4·0.5H2O system was studied using X-ray powder diffraction analysis, differential thermogravimetric analysis, and electronic microscopy. The limits of existence were determined for two types of solid solutions based on the structures of alpha-SrSO4·0.5H2O and beta-SrSO4·0.5H2O.

Metal (Gd, In, Nd, Zr) β-Diketonates and Carboxylates for Designing Element-Containing Liquid Organic Scintillators

G. Ya Novikova et al.

Summary: The research focused on the use of metal beta-diketonates and carboxylates in element-containing liquid organic scintillators, studying their impact on light yield and transparency. Results showed that high specific light yield can be achieved with large concentrations of beta-diketonates, but requires considerable amounts of scintillation additives. Additional studies looked into the stability of metal-containing scintillators, affected by the structure of added compounds and the purity of scintillator components.
