The comparison of two kinds of rare earths

1, re - Alumina Oxides alloy in the middle
Single rare earth metal chemical is high, easy oxidation burning loss during smelting, storage and transportation is not very convenient, cost is high, and high melting point, density, not easy to add to the aluminum. In most cases, therefore, are among the prefabrication of the rare earth - aluminum alloy, not only can reduce the oxidation burning loss, reduce the cost, and convenient transport. Join, simple and safe operation, and components are easy to control, available composition is stable, reliable quality of the alloy.
2, rare earth application in high purity aluminum powder capacitor
Containing rare earth high purity aluminum special aluminum foil, is an ideal new material in the low production of electrolytic capacitors. Some capacitor factory that, after adding trace rare earth in high purity aluminum, can dramatically increase the corrosion of aluminum electrolytic capacitor anode aluminum foil coefficient K, and the strength, capacitance is increased significantly. Made significantly smaller capacitor, the material has been batch used in some of the capacitor, and obtained a certain effect. But the effect mechanism of rare earth in them, have different opinions, is carrying out in-depth research.
