cerium oxide

基本解释

It does this because heating cerium oxide drives oxygen atoms out of its crystal lattice.
其工作原理是，铈氧化物加热后可以把氧原子从其原有的晶体点阵上剥离出来。
The prototype, which was devised by researchers in the US and Switzerland, uses a quartz window and cavity to concentrate sunlight into a cylinder lined with cerium oxide, also known as ceria.
该机器的原型是由美国和瑞士的研究者们设计的。它利用一个石英窗和腔体将太阳光聚集到一个充满二氧化铈的缸体中。
The device, reported in the journal Science, uses a standard parabolic mirror to focus the sun's rays into a reaction chamber where the cerium oxide catalyst breaks down water and carbon dioxide.
这种在《科学》杂志里所报道的装置使用一个标准的抛物柱面镜把阳光搜集进一个反应室。在这个反应室里，铈氧化物催化剂可以分解水和二氧化碳。

One company exploits this phenomenon by making nanoparticles of the compound cerium oxide, which in that form are chemically reactive enough to serve as a catalyst.
ECONOMIST: Small wonders
Prices have soared: the cost of cerium oxide (often used as a catalyst) has increased sixfold since the start of the year, and is 20 times higher than in 2005.

氧化铈
The nano particles of cerium oxide with high thermal stability and large specific surface area were synthesized via controlling of technological parameters under the hydrothermal conditions.
通过控制水热反应过程中各工艺参数，可制备出粒度微细、粒径分布均匀、具有较大比表面积和良好热稳定性的氧化铈纳米颗粒。
