Effect of particle size, transparency and light intensity on the color of powder

Abstract

In daily life, the color of matter will change in some cases. This paper mainly studies the factors that affect the color of powder. The effects of grinding particle size, transparency of grinding material and solvent medium on the colour of powder were investigated. The innovation of this paper lies in the quantitative measurement and analysis of the color of grinding powder by the method of measuring the wavelength and the light intensity with spectrometer.
