Radiochemistry Aims and scope

Abstract

The compounds KNaCaTh(Si8O20) and Ca2Th(Si8O20) were prepared for the first time by solidphase synthesis. The temperature dependences of the unit cell parameters were studied by high-temperature X-ray diffraction, and the thermal expansion coefficients of the compounds were determined. The IR bands of the compounds were assigned. The incongruent melting point of KNaCaTh(Si8O20) was determined by differential scanning calorimetry.
