A containerless processing method for materials under a state of compensated-gravitation and an apparatus therefor.

摘要

The present invention is to provide a processing method of a material under a state of compensated-gravitation, the method which is capable of forming an easy-handling weightless state for a long period time at low cost in a simple manner and which can contribute to developing useful materials and novel materials and supplying them in bulk; and the apparatus thereof. A pressure medium composed of plural kinds of fluids each of which has a different density is charged in a pressure chamber(1) forming, for example, fluid layers. A material(4, 5) is suspended by way of buoyancy brought by this pressure medium. By properly controlling the density of the pressure medium of plural kinds of fluids, a various kinds of materials having different densities can be supported in a suspending state at an almost constant pressure.
