In this Study, vanadium recovery from the steelmaking converter slag was studied. Salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. Ground slag was roasted after mixing with determined quantities of sodium carbonate. The effect of time and temperature of roasting and sodium carbonate content were studied. The optimum temperatu...

Powders of sodium-carbonate co-substituted hydroxyapatite, having sodium content in the range of 0.25–1.5 wt.% with a 0.25 wt.% step, were prepared by a precipitation-solid state reaction route. Compacts of the powders were sintered in a CO2 flow (4 mL/min) at 1100 °C for 2 h. The sintered ceramics contained sodium and carbonate ions in the ranges of 0–1.5 wt.% and 1.3–6 wt.%, respectively, whi...

in this research, kinetics of carbothermic reduction of molybdenite in the presence of different amounts of sodium carbonate has been studied. mixed powders consisting of molybdenite, graphite and sodium carbonate with three mole-ratios of 1:4:2,1:4:3 and 1:4:4 were mechanically activated for 40 hours. the results of x-ray diffraction on activated samples showed that no reaction occurrs in diff...

the effects of cementation and the physical properties of grains on the shear behavior of grouted sands are investigated in this paper. the consolidated-undrained triaxial shear behavior of three grouted carbonate sands with different physical properties, including particle size distribution, particle shape and void ratio, was studied. two sands were obtained from the north shores of the persia...

This work explores the effect of additives on the pouring temperature in a waterworks and industrial calcium fluoride sludge co-melting system. Two kinds of sludge were mixed in various ratios to find a mixing ratio at which the operating temperature for subsequent additive tests was relatively low. Various proportions of either sodium carbonate (Na2CO3) or potassium carbonate (K2CO3) reagent w...

The application of a linear algebraic method to the potentiometric titration of a mixture of tartaric and citric acids and sodium carbonate and sodium hydrogen carbonate (previously treated with strong acid), permits the determination of the concentration of each individual acid and the total equivalent of carbonate in antacids. It is also possible to determine individual concentrations of sodi...

OBJECTIVE To describe the use of sodium carbonate and apomorphine in a historical cohort of dogs, compare the occurrence of emesis and report any adverse effects recorded. METHODS This historical, observational study included information from medical records of dogs that received an emetic agent. The occurrence of emesis with apomorphine or sodium carbonate was calculated and the association ...

Approximately a third of the total body sodium content of man, dogs, and rats is present in the inorganic portion of the skeleton (l-3). Although the magnitude of this fraction and its variability in acidosis and sodium depletion have been defined by direct analysis and by the use of isotopes, the precise position which sodium occupies in bone salt remains obscure. Harrison (4), pointing out th...
