Trans. Nonferrous Met. Soc. China 24(2014) 3378-3385 Non-isothermal kinetic analysis of thermal dehydration of La2(CO3)3·3.4H2O in air Xiang-hui Zhang1, Chuan He2 , Ling Wang1, Jing Liu1, Miao Deng1..., FTIR and DTA-TG. The kinetics of dehydration of La2(CO3)3·3.4H2O in the temperature range of 30-366 °C was investigated under non-isothermal conditions. Flynn-Wall-Ozawa and Friedman isoconversion......
by the intermediate production Ca[Zn(OH)3]2·2H2O and phosphoric acid. The CaZn2 (PO4)2·2H2O molecular is decomposed to CaZn2 (PO4)2 in two dehydration reactions stage: the first stage of dehydration temperature is from 95 ℃ to 393 ℃, and the second stage of dehydration temperature is from 403 ℃ to 553 ℃. Key words: hydrothermal synthesis; ultrafine CaZn2 (PO4)2 powder; reaction mechanism; dehydration process 磷......
