Methods for manufacturing surface-modified inorganic oxide particles and surface-modified silicon dioxide particles

Abstract

A surface-modified inorganic oxide particle is characterized in that, in a diffuse reflectance measurement based on a UV-Vis spectrophotometer, when the K / S value obtained using the Kübelka-Monk function based on the diffuse reflectance at the peak position of a diffuse reflectance peak having a peak in the range of 270-320 nm is set as A, and the K / S value obtained using the Kübelka-Monk function based on the diffuse reflectance at a position of 500 nm is set as B, the amount of byproducts calculated by the following formula (1): Byproduct amount = B / A (1) is 0.17 or less. According to the present invention, it is possible to provide inorganic oxide particles that can suppress the thickening of resin compositions when compounded with resins.
