Abstract
The mineralogical, morphological, physical and chemical properties of four different Turkish sepiolites were compared in this study. The mineral matter in the sepiolites, determined by means of X-ray diffraction, is dominated mainly by quartz and dolomite. Sepiolite was identified with the highest degree of crystallization at the peaks from 12.25 to 12.34 Å. All the sepiolite samples show low-calcium content. Based on size distribution results of all the samples, average grain size varies between 0.143 mm and 0.180 mm. SEM and TEM images results show fibrous morphologies.
