The possibility of increasing fracture toughness and strength of alumina ceramics has been achieved recently by incorporating fine SiC particles. One of the many investigated methods for the synthesis of Alumina-SiC composites is by use of pre-coated SiC powders. Gelation of boehmite (AlOOH) in presence of SiC particles have also been attempted. The present study is for obtaining stable, finely dispersed SiC particles in boehmite matrix as precursor material. The effect of pH and solvent medium in the gelation process of boehmite-SiC mixture are followed by optical microscopy coupled with image analysis system and such composites after sintering are evaluated by microstructural observation. Structure-property correlation has been obtained for highly dispersed SiC particles in alumina-SiC nano composites.
