Differential thermal analysis (DTA), thermogravimetry (TG) and differential thermogravimetry (DTG) were used for this purpose. The use of these methods allowed us to determine the temperature ranges of stability, the nature of thermochemical transformations, as well as mass losses associated with dehydration, decomposition and phase transitions.</dcterms:description><dcterms:subject>Physics</dcterms:subject><dcterms:subject>Apatite</dcterms:subject><dcterms:subject>Thermogravimetry (TG)</dcterms:subject><dcterms:subject>Differential thermal analysis (DTA)</dcterms:subject><dcterms:language>English</dcterms:language><dcterms:date>2025-08-08</dcterms:date><dcterms:contributor>Smolyak Svitlana</dcterms:contributor><dcterms:contributor>G.V.
