چکیده
The advantages of microwave technology over conventionally conducted experiments are numerous. Some them reduction in reaction time, a higher degree process control, repeatability, and work safety. Microwave synthesis routes require complete description the experimental details, instrumentation, design program oven used experiments. In this work, microwave-assisted hydrothermal hematite (?-Fe2O3) particles from 0.1 M FeCl3 solution highly alkaline media with heating at continuous emission 800 W 150 °C, 200 250 °C for 20 min presented. Also, influence percentage addition cationic surfactant, cetyltrimethylammonium bromide (CTAB) on composition, size, shape final product was investigated. samples precipitated formed consisting goethite (?-FeOOH) contrast to those where pure phase obtained. these routes, CTAB caused slow down rate goethite-to-hematite transformation temperatures but did not affect °C.
