Absorptivity of Rare Earth Elements La and Ce in Pure Copper and Influence of Them on Structure of Pure Copper
Choosing rare earth elements La and Ce, the absorptivity of them in pure copper was researched from the category of rare earth, the melting point, the adding methods and quantity, the casting temperature, the time of heat preservation and so on. The factors of affecting the absorptivity were found through the research. The distribution of rare earth, the existent state and the formative compounds in pure copper were observed in as-cast. The absorptivity of the rare earth in pure copper, the influence of them on the microstructures and properties of pure copper were analyzed.
