Examination of the surface properties of ceramic micro and nanoparticles

Abstract: Purpose: The purpose of the article is to examine surface properties of ceramic nanoparticles applied as fillers in composite materials of polymeric warps. Design/methodology/approach: For research there were used three types of ceramic micro and nano fillers: silver sodium hydrogen zirconium phosphate AlphaSan RC2000 (Milliken Chemical) and silica Aerosil DT4 and Aerolisl R 812 (Evonik Corporation). For the purpose of mentioned materials above there were used: scanning electron microscope SEM, Transmission Electron Microscope TEM and gas adsorption method for the purpose of qualifying specific surface area BET, Langmuria, porosity BJH and energy adsorption. Findings: On the base of undergone research there were pointed out dependence between size, shape, porosity of particles and specific surface area BET, Langmuira and energy of adsorption. Practical implications: Methods of measurements based on gas adsorption belong to the types of measurement methods that are very intensively developing that allows undergo measurements of various surface properties meaningful both in material engineering as well as in catalectic chemistry. Originality/value: Specific surface area measurement by gas adsorption method execution. Examination with transmission electron microscopy technique.
