متن کاملEffect of CO2 Partial Pressure on the Thermal Decomposition Kinetics of Zinc Carbonate Hydroxide (TECHNICAL NOTE)
In this work, the effect of carbon dioxide partial pressure on the calcination kinetics of high purity zinc carbonate hydroxide has been studied. Non-isothermal analysis has been performed on samples at different CO2 partial pressures by TGA and DTA. It has been found that the calcination behaviour of this material corresponds to the shrinking core model and the reaction mechanism is phase boun...
متن کاملA Comparative Investigation of Lead Sulfate and Lead Oxide Sulfate Study of Morphology and Thermal Decomposition
The compound lead oxide sulfate PbSO4.PbO was prepared in our laboratory. The Thermal behavior of PbSO4 was studied using techniques of Thermogravimetry under air atmosphere from 25 to 1200 ̊C. The identity of both compounds was confirmed by XRD technique. Results obtained using both techniques support same decomposition stages for this compound. The electron microscopic investigations are made ...
متن کاملPreparation of porosity-controlled calcium carbonate by thermal decomposition of volume content-variable calcium carboxylate derivatives.
We demonstrate a novel approach for synthesizing porosity-controlled calcium carbonate by one-step thermal decomposition of various calcium carboxylate derivatives as well as their mixtures with different molar ratios. By varying the volume content of calcium in the calcium compounds or mixtures, the resulting porous calcium carbonate exhibits distinct porosity and structures that are very prom...
متن کاملSynthesis of gamma ferric oxide by direct thermal decomposition of ferrous carbonate
Ferrous carbonate was precipitated from the reaction of ferrous sulfate and sodium carbonate in an aqueous medium. The precipitate was calcined at different~eating rates (2, 5 and 10 °C/min, respectively) up to 500°C and the iron oxides produced were found to be magnetic. X-ray diffraction studies indicated the presence of gamma ferric oxide as a major phase in all the cases. It was found that ...
