Clean Production of Lanthanum Acetate 制备醋酸镧的清洁生产循环工艺研究
Nanometer-sized ZnO/ La2O3 was prepared by solid phase synthesis. Deferent zinc salt, sodium carbonate and lanthanum acetate were used as starting material. 以不同的锌盐、无水碳酸钠和乙酸镧为原料,采用固相法合成了纳米ZnO/La2O3粉体。
Studies of Synthesis and Characteristics of the Mixed Ligand Corrdination Compound from Lanthanum Acetate with the Ligands Containing Nitrogen 乙酸镧与含氮配体混配配合物合成及性质研究
Lead acetate, lanthanum acetate, bismuth acetate, zirconium oxide acetate and titanium butoxide were used as precursors, bismuth and lanthanum doped continuous lead zirconate titanate gel fibers were fabricated by the sol-gel method. 选用醋酸铅、醋酸镧、醋酸铋、丙醇锆和钛酸四正丁酯为原料,以乙二醇甲醚为溶剂,用溶胶-凝胶法制备铋和镧掺杂的连续锆钛酸铅纤维。
Sample was prepared by gel-solid phase, with aluminium isopropoxide and lanthanum acetate as starting materials, According to TG-DTA curve synthesis temperature of lanthanum aluminate was 900 ℃, coincide with the XRD. 以异丙醇铝和醋酸镧为原料,采用凝胶固相法制备样品,根据TG-DTA分析曲线得出铝酸镧的合成温度为900℃,与XRD分析结果吻合。
