And especially reviewed these methods 'application in the preparation of cobalt aluminate pigment. 重点介绍了这些方法在纳米钴蓝颜料制备中的应用。
It was identified that the grain refinement of the castings is dependent upon the decomposition of cobalt aluminate and the active alloying elements contained in the alloy. 用X射线,显微镜和电子探针法对效果不同的型壳作了分析,发现铸件晶粒的细化与铝酸钴的分解以及合金中的活性元素有关;
After the alloy casted, the isolated particles of high temperature type cobalt were found on the surfaces of the investment mold and the castings, as well as the products of the mixture of cobalt aluminate together with different active elements heated under vacuum. 从浇铸后的型壳表面、铸件表面以及铝酸钴粉加不同活性元素的真空加热后的产物中均发现了Co(高温型)粒子。
