Abstract
Darbā tika sintezēti un analizēti cinku saturošie kalcija fosfāti ar teorētisko Ca/P molāro attiecību 1,5 un cinka saturu 0, 1, 3 un 5 %. Paraugu primārai žāvēšanai izmantoja organiskos šķīdinātājus – etilspirtu un propanolu-2. Paraugiem noteica fāzžu sastāvu, izmantojot rentgendifraktometrijas metodi, noskaidrota esošo elementu oksīdu veida saturs, novertēta nogulsnēto daļiņu forma un, izmantojot diferenciāli termisko analīzi noskaidrota savienojumu fāžu pārējas temperatūra.
In this research are synthesized and analyzed zinc-containing amorphous calcium phosphates samples with zinc assay 0, 1, 3 and 5 % and Ca/P molar ratio 1.5. As a sample for primary drying were used organic solvents, ethyl alcohol and isopropyl alcohol. Phase state of precipitated samples identyfied by x-ray crystalography method, element–oxide procentual attitude – by x-ray fluorescence spectrometry, particles size determined using scaning electron microscope and thermal stability and phase transition – by thermogravimetry method.
