PROBLEM TO BE SOLVED: To provide a method for producing SiO, which is low in production energy and has high productivity.SOLUTION: Firstly, a raw material including SiOis fed into a furnace. Then the raw material 7 is heated by an arc discharge using a carbon electrode 8, and carbon vapor is supplied to the raw material 7 from the carbon electrode 8. The SiOof the raw material 7 is reduced by a reducing agent including carbon vapor to produce SiO vapor. Then the SiO vapor is solidified to recover SiO. An arc discharge part using the carbon electrode locally and instantaneously reaches a high temperature, so an efficient reaction field can be generated. Further, the carbon vapor of high chemical activity is stably supplied to the raw material from the carbon electrode, so the reaction speed of reduction reaction is extremely fast. Consequently, the method for producing the SiO, having high productivity with low energy is accomplished. |
