Phase relations of some tungstate minerals under hydrothermal conditions
The binary phase relations ofseveral naturally-occurring tungstats mins14ls, ofthe general form M2*WOae w€t€ investigated hydrothermally at fluid pressure of 1.0 kbar and temperatures of 400o-900oc. A complete solid solution, with tetragonal symmetry, between scheelite (M2* Ca) and Stolzite (Pb) forms above725"C. The solvus is alnost symmetrical with a crest near CaorPbrr. The observed linear v...
متن کاملRotor-like ZnO by epitaxial growth under hydrothermal conditions.
Rotor-like ZnO was grown from a mixture of rod-like ZnO powder and a saturated Zn(OH)(4)(2-) solution under moderate hydrothermal conditions at 100 degree C, in which the precursor rod-like ZnO crystal plane acts as a matrix core, and the branched nanorods showed fast epitaxial growth on the six directions around the prism core.
متن کاملGROWTH OF ZnS SINGLE CRYSTALS BY CVT TECHNIQUE UNDER DIFFERENT MASS TRANSPORT STABILITY CONDITIONS
Abstract: A thermodynamic model was used to find out the optimum temperature for the growth of ZnS single crystals in closed ampoules by chemical vapor transport technique. Based on this model 1002 °C was found to be optimum temperature for 2 mg/cm3 concentration of transporting agent (iodine). ZnS Crystals were grown in optimum (1002 °C) and non-optimum (902 °C and 1102 °C) temperatures. The c...
متن کاملSpeciation of Molybdates under Hydrothermal Conditions
In situ Raman spectroscopy was applied to investigate the speciation of molybdates under hydrothermal conditions in 0.2 M aqueous solution in the temperature range between 20°C and 200°C and at pH values between 7 and 1. The nature and abundance of molecular and supra-molecular species differs significantly compared to the distribution of species under ambient conditions at the same pH. Whereas...
متن کاملNanoscopic characteristics of anhydrite (100) surface growth under mild hydrothermal conditions
Anhydrite (CaSO4) is a major component of evaporitic rocks and is currently forming in submarine hydrothermal fields, where its dissolution and precipitation plays a significant role in controlling porosity. Anhydrite also is a component of undesirable scale on heat transfer surfaces during desalinization and waste water treatments. Knowledge of the molecular processes that control anhydrite gr...
