Doping Effect on Crystal Structure and Magnetic Properties of Highly Al-substituted Strontium Hexaferrite Nanoparticles
M-type strontium hexaferrites with substitution of Fe3+ by Al3+, according to the formula
SrAlxFe12-xO19 (x=0, 1, 2, 3, 4, 6, 8, 10), are prepared by the sol-gel auto-combustion method.
Influences of the substituted amount of Al3...
Effect of calcination temperature on catalytic activity of synthesis SrO/S-ZrO2 by solvent-free method in esterification of oleic acid
of the catalysts. The results of this study reveal that the calcined strontium oxide promoted sulfated zirconia at 500 oC has the highest percentage of tetragonal phases of zirconia. It has also been demonstrated that owing to the high percentage of the tetragonal...
Effect of adsorbents and chemical treatments on the removal of strontium from aqueous solutions
In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent types and chemical...
