Review of the containerless processing technologies and facilitiesMaterial processing techniques which can most fully utilize the advantages provided by space are related to containerless processing. An avoidance of physical contact between the melt and the walls of a container leads to an elimination of container-induced contamination and heterogeneous nucleation. Containerless processing facilities development by NASA will provide a basis for the performance of precursor experiments and processing technologies studies prior to Space Shuttle flights. Attention is given to acoustic containerless processing, electromagnetic containerless processing, electrostatic levitation technology, drop tubes, and the use of zero-G KC-135 aircraft flights for tests and training purposes.
