This project investigated the effect of compacting pressure and sintering temperature on supports’ physical and mechanical properties. The supports were prepared by axial compacting of a Al₂O₃ powders using pseudoboehmita and silica gel as binder. Hydrated magnesium oxide was used as sintering helper. The prepared agglutinants were characterised by x-ray sedigraphy. The supports were synthesised by SEM and their compression strength and porosity were evaluated and characterised by EDX sweeping electron microscope (SEM). These binders and the helper were prepared by the sol-gel process.

Keywords : sol-gel; membrane; support; sintering; SEM.
