Processing and Characterization of Limestone Nanoparticles

Abstract

The effective application usage of solid materials of cannot be granted if the fundamental properties of the material are unknown. Material characterization is one of ways science due apply to determine the fundamental properties of any material. The characterizations of materials in the various discipline of science are of different methods. This research work, processing and characterization of limestone nanoparticles as concern the field of material science was experimentally studied on three major categories: The micro structure using an optical microscope, in which the micro-structure image was obtained at its particulate of approximately 2.5nm. The absorbance obtained experimentally using an ultraviolet-visible spectrophotometer at wavelength raging from 190nm to 900nm. The transmittance, reflectance, refractive index was obtained mathematically, with the optical band gap obtained to be equal to 1.62eV. Finally the elemental composition was obtained using an Atomic Absorption Spectrometer (AAS), at which calcium was found to have the highest concentration among other metal present in the limestone nanoparticle.
