Effect Of Mg/Cu Additives On The Ability To Synthesize SiC From Rice Husk

Silicon carbide is a chemical compound known for its high mechanical strength and exceptional thermal resistance. However, its synthesis typically necessitates very high temperatures and involves complex manufacturing techniques. Consequently, numerous studies have sought to lower the synthesis temperature of SiC by employing biomass-derived precursors. Despite these efforts, the efficiency of the SiC synthesis reaction remains low, resulting in suboptimal production yields. This study examines the impact of additives, specifically magnesium and copper, on the formation of SiC . Differential Scanning Calorimetry analysis of the mixtures indicates magnesium additives can facilitate earlier SiC formation compared to copper ( 466.73 degrees C vs. 522.02 degrees C ). According to ISO 20068:2008 standards for SiC composition determination, at a sintering temperature of 1000 degrees C, copper additives are more effective in generating SiC than magnesium. Analysis of SiC composition and X-ray diffraction patterns reveals that magnesium and copper additives significantly enhance the quantity of SiC produced. However, these additives also introduce numerous impurities into the final product. These impurities can be mitigated through acid washing.
