Abstract
Synthesis, characterization and optical band gap of Pirochromite (MgCr2O4) Nanoparticles by Stearic Acid Sol-Gel Method
Highlights
Nanoparticles have unique properties, such as high resistance, toughness, and rigidity, due to their high surface area to volume ratio
MgCr2O4 is traditionally created by a solid state reaction that requires a high temperature, which leads to a lower specific surface area and lower catalytic activity for the synthesized material, Synthesis and Characterization of Pirochromite (MgCr2O4) Nanoparticles by Stearic Acid Sol-Gel Method was successfully prepared in this study
The highest degree of crystallite was achieved when the calcined temperature occurred in the synthesis process[17]
Summary
Nanoparticles have unique properties, such as high resistance, toughness, and rigidity, due to their high surface area to volume ratio. Magnesium oxide is a powder nanocompound; its spinel structure consists of a very large family of compounds with a wide range of physical properties, which has attracted great interest in the scientific community 1. MgCr2O4 is traditionally created by a solid state reaction that requires a high temperature, which leads to a lower specific surface area and lower catalytic activity for the synthesized material, Synthesis and Characterization of Pirochromite (MgCr2O4) Nanoparticles by Stearic Acid Sol-Gel Method was successfully prepared in this study. MgCr2O4, is a well-known refractory material due to its high-melting point (2350°C), high chemical inertness against both acidic and basic slags, and high strength at elevated temperatures. The nanosized spinel particles are greatly desired because nanocrystalline MgCr2O4 spinel particles certainly
