Identification of chlorite and serpentine in cosmetic or pharmaceutical talc.
Chlorite is the most common accessory mineral group found in high purity talc ore used in cosmetic or pharmaceutical consumer talcum products. X-ray diffraction and wet chemical analytical data obtained on geologic samples representing commercial talc ore deposits of high purity and on processed samples representing talc found in consumer talcum products indicate that clinochlore and penninite ...
متن کاملan unusual assemblage of talc-phengite-chlorite-k-feldspar in quartz schists from the nahavand area, sanandaj-sirjan zone, iran
for the first time, an unusual assemblage of talc-phengite-chlorite-k-feldspar was found in quartz schists from the sanandaj-sirjan zone in the nahavand area in western iran. the talc-bearing quartz schists occur as small bodies or lenses within pelitic schist layers and contain talc, phengite, chlorite, k-feldspar and quartz as major mineral constituents with subordinate amounts of calcite ...
متن کاملEfficiency of colloidal pitch adsorption onto phyllosilicates : Comparing talc , chlorite and pyrophyllite
Talc is often used to control unwanted deposition of resins and wood processing derivatives in the wet end circuit of a paper mill. These compounds, called pitch, originate from the raw forest material and are brought into a semi-stable colloidal dispersion during the pulping process. In preceding work we found that the efficiency of different talcs in reducing the level of pitch present in a t...
متن کاملHeat capacity in proteins.
Heat capacity (Cp) is one of several major thermodynamic quantities commonly measured in proteins. With more than half a dozen definitions, it is the hardest of these quantities to understand in physical terms, but the richest in insight. There are many ramifications of observed Cp changes: The sign distinguishes apolar from polar solvation. It imparts a temperature (T) dependence to entropy an...
متن کاملHeat Capacity in Bits
The temperature T may be expressed as the rate of energy increase per unit increase in the state uncertainty under no-work conditions. The consequences of such a choice for heat capacities are explored. I show that the ratio of the total thermal energy E to kT is the multiplicity exponent ~log–log derivative of the multiplicity! with respect to energy, as well as the number of base-b units of m...
