Combustion synthesis technology can be advantageously applied to high-temperature experiments under microgravity environments(MOE) not only as a direct synthesizing method for high-temperature materials but also as a super-heating chemical oven, because it is possi­ble to get high temperatures more rapidly compared to conventional electric furnaces. In the present work, the combustion synthesis of ZrO2-A}zO3-Fe and TiB2-Al-B composite systems have been carried out using a TR-IA sounding rocket which provides about 10- 4 g0 for six minutes. As the former result, more uniform distribution and finer particles of ZrO2 could be attained under MOE, which would be caused from no disturbance in mass migration. As the latter, the composite layered particles composed of TiB2 and Al-B system synthesized under MOE were more uniform compared to those obtained on earth, which would result in the formation of denser cermet-like products.
