Item Obtención de óxidos metálicos mixtos desde combustión cítrica modificada con extracto natural aloe vera (Aloe barbadensis Miller)(Universidad Santiago de Cali, 2023) Gómez Lara, Kevin Steven; Morales Morales, Jimmy Alexander (Director); Granja Banguera, Claudia Patricia (Codirectora)This work consisted of the preparation of calcium ferrite through the modified citrus combustion route using natural aloe vera extract, from the mixture of solutions of Ca(NO3)2•4H2O and Fe(NO3)3•9H2O, extract of aloe vera, with constant stirring, and assisted in a conventional microwave, until obtaining a porous solid that was subsequently calcined in a muffle at different temperatures between 500 and 900ºC, and then macerated with agate mortar. This material is deposited in a vial to finally be characterized by analytical techniques such as X-ray diffractometry (XRD), vibrational spectroscopy in the infrared region (IR), thermogravimetry (TGA).
