To produce a high quality electronic, optical or superconducting material of conventionally unattainable large size by holding a large material of arbitrary shape in a space in noncontact state and then heat treating it at a high temperature.
A material is held in a space, in noncontact state, by the pressure of gas fed from a nozzle and then heat heated simultaneously at high temperature by the gas pressure for floating by heating the flowing gas while controlling the temperature thereof. A material of arbitrary shape can be floated in noncontact state by varying the shape of the nozzle and since the gas pressure floating mechanism is not dependent on the physical values of the material, any material, including magnetic materials, dielectrics and glass, can be floated in noncontact state using the same mechanism.
