Preparation of calcium plumbate via different route

Popis výsledku v původním jazyce

Calcium plumbate Ca2PbO4 was prepared by sol-gel methods (Pechini complex route with two varieties and water soluble polymer method) and by solid state reaction. The sol-gel prepared samples contained calcium plumbate as the only one phase as early as after 2 h annealing at 800 degrees C. Phase composition was detected by XRD measurement and by Raman spectroscopy. The next annealing at 800 degrees C for 24 h induced weak Pb losses displayed by present CaO (according to phase equilibrium) and confirmed by XRF measurement. The Pb losses were smaller for the sol-gel prepared samples probably due to earlier formation of Ca2PbO4. Microstructure and grain size were also established. Sol-gel prepared samples had regularly distributed grains with a small distribution interval with median value in order of 1 mu m. Differences in microstructure of solid state and sol-gel samples are presented on SEM micrographs.
