Abstract

In this research, the analysis of mullite-bonded Silicon carbide and also its flexural strength is being conducted. The analysis of the silicon carbide is based on the various uniaxial mechanical pressure and milling duration. The analysis method that used in this research are flexural test, density test, microstructure observation and phase observation. The microstructure observation is implemented by using the Scanning Electron Microscope (SEM) while for the phase observation, it is being done by using X-Ray Diffraction (XRD) tools. The objective of this research is to identify the optimum uniaxial pressure during the preparation of the mullite bonded Silicon carbide‘s green body. Besides that, the mechanical properties of Mullite-bonded Silicone Carbide which is fabricated at various uniaxial pressure and grinding duration also will be study. The result have shown that the highest pressure and milling hour applied to the Silicon Carbide will indicates the highest value of flexural strength and density. The result of microstructure observation and phase observation also show the effect of pressure and milling hour to the microstructure and phase. For the phase observation, the mullite phase is found in the Silicon Carbide.
