| Summary: | Заглавие с экрана The laser diffraction method is extensively used for dispersion analysis of nanoparticles, but the variety of particles produced does not allow the identification of patterns between nanoparticle properties and the results obtained. This work focuses on determining the effect of the laser beam reflection index from the material surface on the resulting particle size distribution in aqueous suspension for titanium dioxide nanoparticles, in the form of anatase (40 nm) and rutile (150 nm). It is experimentally shown that for anatase nanoparticles, when the reflection index increases relative to its true value (from 2.40 to 2.80), the particle size distribution shifts to the left (toward decreasing particle size), and when it decreases (from 2.40 to 2.10), it shifts to the right (increasing particle size). For rutile nanoparticles the change of reflection index in the range from 2.10 to 2.80 does not affect the shape of particle size distribution Текстовый файл |
