查询词典 cerium dioxide

The results show that there are little difference of CO sensitivity between precipitation transformation method and sol-gel method, the sensitivity of copper oxide loading on zirconium oxide or cerium oxide is better than that of loading on alumina or silicon dioxide, the optimal calcinations temperature is 500 Celsius degree and the optimal copper content loading on cerium oxide is twelve percent.

实验结果表明，材料的制备方法对气敏性质的影响不大；锆铈基氧化物的气敏性质较高，而Al2O3，SiO2作载体时效果要差一些；焙烧温度在500℃时对CO具有最好的灵敏度；当负载在氧化铈载体上的氧化铜含量为12%时，对CO的气敏性质最高。

A cerium dioxide target was used for sputtering and films were deposited at various substrate temperature under different sputtering power.

溅射过程中，首先制备纯二氧化铈靶材，然后在不同的功率上调节不同的基片温度进行溅射。

Cerium dioxide thin films were deposited on glass substrates using R. F. magnetron sputtering.

本文采用射频磁控溅射法在玻璃基片上沉积CeO2薄膜。

The results indicate that NH4Cl directly takes part in the chlorination of cerium dioxide by forming an intermediate CeOCl rather than by the HCl decomposed from NH4Cl.

结果表明， CeO2在空气气氛下采用NH4Cl氯化，在300 ℃下其氯化率达到80%左右，更高的温度反而不利于CeO2的氯化，这主要是由于CeCl3*7H2O的热分解造成的。
