一般說明

硝酸镧(III)水合物是一种白色结晶固体，极易溶于水。还用于各个领域，如催化剂、陶瓷、作为化学合成中的镧离子源。

應用

硝酸镧(III)水合物可用于：
  • 作为合成锆酸镧纳米颗粒的原料。
  • 作为制备发光镧-三羧基三苯胺（La-TCA）配位聚合物纳米片的前驱体。
  • 制备用于化学传感器的钙钛矿氧化物型LaFeO3枝晶。
  • 柠檬酸溶胶–凝胶法合成LaMnO3钙钛矿催化剂，共沉淀法合成La0.6Sr0.4MnO3钙钛矿。LaMnO3钙钛矿催化剂已用于丙烷的氧化，从而控制烃类挥发性有机化合物的排放。

The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.

我们的科学家团队拥有各种研究领域经验，包括生命科学、材料科学、化学合成、色谱、分析及许多其他领域.
