Applications of mica-based pearlescent pigments are related to plastics, cosmetics, automobiles coatings among others, but they seem to be not explored by the ceramic industry. In this work, intensively red and gold colored muscovite pigments covered with layer of nanoparticles containing iron and zirconium oxides were prepared by homogeneous precipitation. The final color was obtained after th...

We appreciate that Rasmussen et al. (2011) have characterized a large number of inclusions in Jack Hills (Australia) detrital zircons, but we fi nd two signifi cant fl aws in their paper: one of scholarship and one of omission. With regard to the fi rst, their paper implies discovery of reset isotopic systems in phosphate inclusions in Jack Hills zircons. This was previously discussed by Caro e...

Impurities are detrimental to silicon-based solar cells. A deeper understanding of their evolution, microscopic distributions, and oxidation states throughout the refining processes may enable the discovery of novel refining techniques. Using synchrotron-based microprobe techniques and bulk chemical analyses, we investigate Fe, Ti, and Ca starting from siliconand carbon bearing raw feedstock ma...

The advent of a new method for measuring the zeta potential of planar surfaces, the rotating disk, allowed the investigation of the charging process of mica after immersion in water. The zeta potential of freshly cleaved muscovite mica was recorded within seconds of immersion of the sample and in fractions of a second thereafter. The zeta potential of mica in water at pH = 5.6 with no added pot...

The study aimed to find the origin of high lithium content groundwater in southeast Hungary. To be concerned with assessing economic potential these waters, it is necessary investigate lithium-releasing geochemical processes. For this purpose, granite and pegmatite samples were analysed for alteration from various Battonya Complex locations. key processes are chloritisation biotite sericitisati...
