The effect of ultrasound on the particle size and structural disorder of a well-ordered kaolinite.
TL;DR: Investigating the effect of sonication on the particle size and structure of a well-crystallized (KGa-1) kaolinite from Georgia showed that particle-size reduction can be controlled through different variables such as power of ultrasonic processor, amount of sample, and time of treatment.
Journal ArticleDOI
Effects of Dry Grinding on the Structural Changes of Kaolinite Powders
Pedro José Sánchez-Soto,María del Carmen Jiménez de Haro,Luis A. Pérez-Maqueda,Ignacio Varona,Jose Luis Perez-Rodriguez +4 more
TL;DR: In this paper, the effects of dry grinding on the structure of well-crystallized and poorly crystallized (KGa-1 and KGa-2) kaolinite powders from Georgia were examined.
Journal ArticleDOI
Comparison between micro-Raman and micro-FTIR spectroscopy techniques for the characterization of pigments from Southern Spain Cultural Heritage
M. L. Franquelo,Adrian Duran,Adrian Duran,L.K. Herrera,M. C. Jiménez de Haro,Jose Luis Perez-Rodriguez +5 more
TL;DR: An extensive overview of the complementary use of micro-FTIR and micro-Raman spectroscopy in the Cultural Heritage studies is described in this article, where samples have been prepared using the cross-section technique, which allows the examination of a large portion of a single paint layer in its original condition.
Journal ArticleDOI
Talc from Puebla de Lillo, Spain. II. Effect of dry grinding on particle size and shape
Pedro José Sánchez-Soto,A. Wiewiora,M.A. Avilés,Ángel Justo,Luis A. Pérez-Maqueda,Jose Luis Perez-Rodriguez,Paweł Bylina +6 more
TL;DR: The effect of dry grinding on the structure, particle size and shape of talc from Puebla de Lillo (Leon, Spain) was studied by means of nitrogen adsorption, XRD, DTA-TG and by SEM-EDS methods.
Journal ArticleDOI
Preparation of submicron talc particles by sonication
TL;DR: In this article, a sonication procedure was performed on talc with sizes in the submicrometer range and the resulting materials presented a narrow particle size distribution and retained the crystalline structure of the parent mineral, as assayed by X-ray diffraction and FTIR spectroscopy experiments.
