Abstract: PURPOSE:To produce vanadium suboxide at a low cost without feeding reducing gas from the outside by introducing NH4VO3 into an inactive heat resistant reaction vessel and heating it at the specified temp. and removing air by means of generated gaseous NH3 and also holding the inside of the vessel in the specified conditions. CONSTITUTION:NH4VO3 or NH4VO3 mixed with <=15% V2O5 is introduced into an inactive heat resistant reaction vessel and heated at 380-750 deg.C in 0.5-30 deg.C/min temp. raising velocity so that the outside air does not infiltrate thereinto and held in this state for 30min-3hr. In the meantime, NH4VO3 incorporated in the reaction vessel is pyrolytically decomposed and gaseous NH3 is generated and gas pressure is raisen. Therefore the gas pressure is held in about 3atm or below by a pressure-control valve, an excess gas is discharged together with air to the outside of the system. In the inside of the reaction vessel, higher vanadium oxide (V2O5 or the like) produced by the pyrolysis of NH4VO3 is reduced to V6O13 or V2O4 of suboxide by gaseous NH3. Thereafter the reaction reactor is cooled while keeping the outside air from infiltrating thereinto and vanadium suboxide is taken out from the reaction vessel.

When the interior of the vacuum chamber 2 is fully exhausted by the vacuum pump during the temperature in the vacuum chamber 2 is sufficiently high, gas in the heat insulating body 4 is almost completely evacuated, and at the same time, the interior of the vacuum chamber 2 is brought into a vacuum state. When the degassing of the heat insulating body 4 is insufficient by a heating of one time, gas, which is hardly to adsorbed to the heat insulating body 4 like nitrogen, is introduced in the vacuum chamber 2, and after that, a heating and an evacuation are performed. Nevertheless, when the degassing is still insufficient, the abovementioned operation is repeatedly performed. By this way, it is completely attained to bring the heat insulating body 4 into the degassing state and it is completely attained to bring the interior of the vacuum chamber 2 into a vacuum state.
