Molybdenum trioxide consisting of an aggregate of primary particles having a β crystal structure of molybdenum trioxide, the content of MoO 3 measured by fluorescence X-ray (XRF) is 99.6% or more, and the average particle diameter of the primary particles is 1 μm or less powder. Vaporizing the molybdenum oxide precursor compound to form a molybdenum trioxide vapor, and cooling the molybdenum trioxide vapor, the manufacturing method of the molybdenum trioxide powder. |
