Progress of Microgravity Material Research During the Period of 2007-2009

Orbital experimental researches on crystal growth of Mn-doped GaSb and Bi2Se0.21Te2.79 are briefly summarized.The space experiments were completed in September of 2007 on broad the Foton-M3 satellite of Russia.Ground-based researches on the solidification behaviors of Al-Al3Ni,AlAl2Cu,Ag-Cu eutectic,Al-Pb monotectic and Cu-Co peritectic alloys in a 50-meter-high drop tube were investigated.New experimental results on the ultrasonic field and the temperature recycling induced to chiral symmetry breaking of NaClO3 crystal also were reported in the present paper.

Orbital experimental researches on crystal growth of Mn-doped GaSb and Bi2Se0.21Te2.79 are briefly summarized. The space experiments were completed in September of 2007 on broad the FotomM3 satellite of Russia. Ground-based researches on the solidification behaviors of A1-A13Ni, A1- A12Cu, Ag-Cu eutectic, A1-Pb monotectic and Cu-Co peritectic alloys in a 50-meter-high drop tube were investigated. New experimental results on the ultrasonic field and the temperature recycling induced to chiral symmetry breaking of NaC103 crystal also were reported in the present paper.
