Abstract
[Problem to be solved] To produce an SiO powder having a rounded spherical particulate shape and a small particle diameter; and further having a low degree of impurity contamination, efficiently and economically. [Solution] A mixture of Si and SiOas an SiO gas generation raw materialis loaded into a crucible. The mixture in the crucibleis heated under a reduced pressure so as to generate SiO gas. The generated SiO gas is accumulated on a deposition baserotating on the crucible. When SiO depositaccumulated on the deposition baseis scraped off with a blade, a tip of the bladeis separated from a surface of the deposition base, and in a state in which a portion of the SiO depositaccumulated on the deposition baseis left on the deposition base, the remaining SiO depositis scraped off by the bladeand collected as an SiO powder
