Application Research on Controlled Directional Solidification Purification Technology for High-pure Aluminum

High purity aluminum is mainly the new electronic material. High purity aluminum has the advantages of high purificaiton and low cost by aid of the method of controlled directional solidification technology. The method has been used widely in the dustry currently. The principle of controlled directional solidification technology was introduced simply. The new process and new method of the technology at home and abroad were emphasized in the paper. The problems exsited in controlled directional solidification technology for high purity aluminum and development trends were analyzed and summarized.
