Abstract: Niobium oxide particles which have a controlled crystal shape and exhibit excellent characteristics are provided. The niobium oxide particles include molybdenum. The niobium oxide particles preferably have a polyhedral, columnar or acicular shape. The MoO3 content (M1) measured by XRF analysis of the niobium oxide particles is preferably 0.1 to 40 mass % relative to the niobium oxide particles taken as 100 mass %. A method for producing the niobium oxide particles described above includes calcining a niobium compound in the presence of a molybdenum compound.

Abstract: It relates to tantalum oxide particles containing molybdenum. The tantalum oxide particles preferably have a polyhedral shape, and the crystallite size of the tantalum oxide particles at 2θ=22.8° is preferably 160 nm or more. It also relates to a method for producing the tantalum oxide particles, the method including firing a tantalum compound in the presence of a molybdenum compound.
