Abstract

Silicon carbide (SiC) and SiC-C composite are non-oxide materials with good thermal properties so that they can be widely applied in industry. SiC can be synthesized by the magnesiothermic reduction method at a relatively lower temperature compared to carbothermal reduction. Rice husk charcoal has potential silicon and carbon content so that it can be used as a base material for the manufacture of SiC. This study aims to study the effect of calcination temperature in argon gas medium on the formation of SiC-C composites from rice husk charcoal reduction products using the magnesiothermic reduction method. The research methods include carbonization of rice husks, synthesis of SiC with magnesiothermic reduction method, calcination in argon gas medium for reduction products, and product purification, and product characterization. Calcination at the SiC-C composite formation stage was carried out at various temperatures of 700 and 1000 oC. The synthesized products were further characterized by FT-IR and XRD. Characterization by FT-IR showed that SiC was formed by magnesiothermic reduction method, while based on characterization by XRD, calcination at 700 oC in argon gas medium to the reduction product produced SiC-C composites with the highest content.

Abstract

Forsterite has a heat resistance property at high temperatures so it has the potential as a refractory material. As the main agricultural commodity in Indonesia, rice is a potential raw material as a source of amorphous silica and carbon through the partial burning process of rice husks. This study aims to determine the effect of calcination temperature in air medium on the process of forming forsterite from MgCO3 and rice husk charcoal. The forsterite/carbon synthesis was carried out at a mole ratio of MgCO3 to SiO2 of 2:1. The research method includes the preparation of rice husk charcoal by gasification; synthesis of forsterite with variations in calcination temperature at 700, 800, 900, and 1000 oC for 2 hours; and characterization of synthesis results using FTIR and XRD. The results showed that the higher the calcination temperature, based on the formation of bonds from the results of FTIR analysis and XRD diffractogram, the more the forsterite structure was formed. Calcination at 1000 oC is the optimum temperature for the formation of forsterite.
