Particle characterization of nanoparticle materials in water jet mill device

Abstract

Certain optical parameters of nano and micro-structured particles of silica were adjusted and the measurement of the particle size distribution was obtained by using the Mastersizer 2000 device. The optical method process may be used by looking for unique refractive and absorption index of investigated particles. Optical properties (i.e., refractive index) and absorption index of the silicon particles have been found and related to inter-particle silicon bindings in the form of Hamaker constants. For the optical properties, calculations using the Mastersizer 2000 Mie Scattering solutions representing the electric and magnetic induction (i.e., silica's permeability and permittivity from Maxwell's equations) were employed. The silicon nanoparticles were prepared by the water jet mill technology and the research has revealed that the silicon particles were detected in the substance as nanoparticles characterized by the silica optical parameters.
