Abstract
Molybdenum disulfide particles include a 2H crystal structure and a 3R crystal structure of molybdenum disulfide, in which a presence ratio of the 3R crystal structure in a crystal phase of molybdenum disulfide is 10% or more, and a crystallite size of the 3R crystal structure calculated by extended-type Rietveld analysis based on an analysis formula L=Kλ/(β cos θ) using a profile obtained from powder X-ray diffraction (XRD) using Cu-Kα rays as an X-ray source is 1 nm or more and 150 nm or less (in the above formula, K is an instrumental constant that depends on an XRD optical system (an incident side and a detector side) and settings, L is a crystallite size [m], λ is a measured X-ray wavelength [m], β is a half width [rad], and θ is a Bragg angle of a diffraction line [rad]).
