Shape properties of talc and quartz particles ground by a laboratory size ball, rod, and autogenous mills were studied using scanning electron microscope (SEM). More than 100 particles were measured to do the shape analysis of each mill product. The wettability behavior of (gamma(c)) a highly hydrophobic of talc mineral was determined by contact angle measurements and microflotation tests using a contact angle goniometer and EMDEE MicroFLOT test tube, respectively. On the other hand, wettability (gamma(c)) of quartz, which is a highly hydrophilic mineral, was determined by the micro-flotation method only. The results showed that the particles ground by rod mill gave higher flatness and elongation ratio, which meant higher hydrophobicity with lower gamma(c) values in the separations by flotation method.

Role of shape properties of calcite and barite particles on apparent hydrophobicity Ulusoy, U; Hicyilmaz, C; Yekeler, M (2004-08-01) Shape properties of calcite and barite particles ground by ball, rod and autogenous mills were examined by using scanning electron microscope (SEM). Shape properties have been stated in terms of shape descriptors such as elongation ratio, flatness, roundness and relative width by measuring about 200 particles. The results were correlated with the critical surface tension (gamma(c)) of wetting determined by contact angle and micro-flotation methods. The correlations set between the shape properties and the w...
Effect of particle shape and roughness of talc mineral ground by different mills on the wettability and floatability Yekeler, M; Ulusoy, U; Hicyilmaz, C (2004-02-16) In this study, shape characteristics of talc particles produced by ball, rod and autogenous mills were investigated using Scanning Electron Microscope (SEM) and expressed by the shape descriptors such as elongation, flatness, roundness and relative width by measuring on the particle projections in two dimensions (2D). Approximately, 139 particles were measured for image analysis from each mill product. Surface roughness values of talc mineral have been expressed by the parameters of R-a value on the pellete...
Properties of Al2O3: nc-Si nanostructures formed by implantation of silicon ions into sapphire and amorphous films of aluminum oxide Tetelbaum, D. I.; Mikhaylov, A. N.; Belov, A. I.; Ershov, A. V.; Pitirimova, E. A.; Plankina, S. M.; Smirnov, V. N.; Kovalev, A. I.; Turan, Raşit; Yerci, Selçuk; Finstad, T. G.; FOSS, SEAN (2009-02-01) Photoluminescence, infrared Fourier spectroscopy, Raman scattering, transmission electron microscopy, and electron diffraction were used to study the luminescent, optical, and structural properties of aluminum oxide layers (sapphire and films of Al2O3 deposited on silicon) implanted with Si+ to produce silicon nanocrystals. It is established that, in both cases, a high-temperature annealing of heavily implanted samples brings about the formation of silicon nanocrystals. However, the luminescent properties o...
Optical characterization of silicon based hydrogenated amorphous thin films by un-visible and infrared measurements Kılıç, İlker; Katırcıoğlu, Bayram; Department of Physics (2006) Various carbon content hydrogenated amorphous silicon carbide (a-Si1ŁxCx:H) and hydrogenated amorphous silicon (a-Si:H) thin films have been deposited on various substrates by using plasma enhanced chemical vapour deposition (PECVD) technique. Transmission spectra of these films have been determined within UV-Visible region and the obtained data were analysed to find related physical constants such as; refractive indices, thicknesses, etc. Fourier transform infrared (FT-IR) spectrometry technique has been u...
Effect of chemical composition on the optical properties and fracture toughness of transparent magnesium aluminate spinel ceramics Dericioğlu, Arcan Fehmi; Dlouhy, Ivo; Kagawa, Yutaka (2005-05-01) Polycrystalline transparent magnesium aluminate "spinel" ceramics were fabricated by hot-pressing and hot isostatic pressing (HIPing) using commercially available MgO and Al2O3 Powders. Al2O3 content of spinet was systematically changed that can be expressed as MgO.nAl(2)O(3) with n = 1.0, 1.5 and 2.0. UV/visible and near-IR wavelength region light reflection and transmission behaviors of the spinet ceramics were quantitatively correlated to their microstructure to account for the optical quality of the fab...
