The desira­ bility of using smaller amounts of flux was recognized by Finn and So we're gonna start off with your question. Upon heating in air, yttrium, lanthanum, and neodymium precursors underwent two-step decomposition to first form oxycarbonate and then oxide. The X ray diffraction data were indexed in the triclinic system with cell parameters a = 19. The decomposition rate of sodium hydrogen carbonate (NaHCO3) into carbonate (Na2CO3) was determined as weight loss at ambient pressure and elevated temperatures up to 230 °C. The reason behind the low-frequency anomaly has been explained as high-frequency energy attenuation caused by hydrocarbons. Finally, for the anhydrous praseodimium, terbium - lutetium and yttrium compounds, the TG curves show mass losses in two steps with losses of (first step), rest of the ligand DMCP and thermal decomposition of the respectives monoxycarbonates formed during the dehydration of basic carbonate with formation of the oxides, Pr 6 O 11, Tb 4 O 7 and .
