The Structural and Magnetic Variation with Calcinations Temperature in CoO doped Al2O3 Nanocrystallines

Abstract

In present scenario, the technological applications of nanomaterial are at key position because of unique in physico-chemical property at this scale. The present research work explored the effect of concentration of Co element on structural and morphological modifications in Cobaltous oxide Alumina nano-crystalline. In this research work, nanosized Cobaltous oxide Alumina sample was synthesized via advanced co-precipitation chemical protocol. The specimens have been calcined at 200⁰C, 400⁰C, 600⁰C for a time span of 2hours. The XRD results reflects that The crystalline size of newer nanocrystallines were increase in particle size with increase in calcinations temperature Cobaltous oxide Alumina hexagonal structure .The FTIR tools was used to examine the purity of samples and entities  of Cobaltous oxide Alumina structural material. The magnified images of samples were seen through FESEM and HRTEM tools and exhibited structure were 2-D nanosheets were in formation.
