There has been considerable interest recently in microgravity physics and the effects of gravitation on crystal growth, alloy solidification, and other processes in space manufacturing. Regel' 1] has provided an extensive but not exhaustive bibliography on micro gravity physics and materials science in space, in which the major aspects are discussed along with the state of the art and future research prospects. The literature survey in 1] covered a period of about 10 years, including some publications appearing in 1983 that reflected not only theoretical and experi- mental studies completed...
