抄録

We performed sounding rocket microgravity experiments to evaluate the sample position control system for an Electrostatic Levitation Furnace(ELF) for the International Space Station, and we also performed containerless processing of BiFe03 to evaluate its structure. The experiments are successfully conducted and we obtained technical data for the sample positioning function as well as a processed sample BiFe03. The sample position control function was successfully completed, however, sample fluctuation was observed when the sample was heated and melted. The cause of the fluctuation is due to charge loss of the sample. This result indicates us that position control system of the ELF should be detect the charge loss and adjust PID parameters automatically. From the results of sample evalua­tion, fine structure and macroscopic segregation have been found.
