An investigation on thermal behavior of Shahreza dolomite ORE
Thermal behavior of the Shahreza dolomite ore is investigated in this paper. The hydration of the calcined dolomite was studied as a function of the calcination temperature. The DTA results exhibit three endothermic peaks at 800, 900 and 1050 °C, corresponding to decomposition of MgCO3 and CaCO3, both are present in dolomite and free calcite, respectively. The results also indicated that the de...
متن کاملThermal Behavior of a Natural Sepiolite from Northeastern Iran
Sepiolite deposits have been recently discovered in northeastern Iran. However, there is still little information about its physicochemical and mineralogical characteristics. Therefore, the collapse of the sepiolite (with sizes of < 63 μm) structure induced by temperature elevation in an electric furnace at 350, 550, and 850 °C for 4 hours was studied using X-ray diffraction (XRD) in combinatio...

متن کاملMonolayer characteristics and thermal behavior of natural and synthetic phosphatidylserines.
The monolayer properties and thermal behavior of different phosphatidylserines are presented. At neutral pH and 22 degrees C, saturated phosphatidylserines form condensed monolayers while unsaturated phosphatidylserines form liquid-expanded films. Under similar conditions, dimyristoylphosphatidylserine undergoes a transition from the liquid-expanded to the condensed state. At pH 4 and 22 degree...
متن کاملBehavior of Packed Bed Thermal Storage
A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...
