Аннотация: <jats:p> Apatite Pb<jats:sub>3</jats:sub>Bi<jats:sub>2</jats:sub>(GeO_4)<jats:sub>3</jats:sub> was obtained by the solid-phase method from the initial oxides of PbO, Bi<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> and GeO<jats:sub>2</jats:sub> by sequential firing in air at temperatures of 773-1003 K. Its crystal structure has beenПоказать полностьюrefined by X-ray diffraction. The high-temperature heat capacity (350-1000 K) of this compound was measured by differential scanning calorimetry. Based on these data, the main thermodynamic functions are calculated. Keywords: apatite bismuth-lead germanate, solid-phase synthesis, high-temperature heat capacity, thermodynamic properties Keywords: apatite bismuth-lead germanate, solid-phase synthesis, high-temperature heat capacity, thermodynamic properties. </jats:p>
