Effect of binders on microstructural and mechanical properties of sintered alumina

► Binder and sintering temperature affect the microstructural and mechanical properties of alumina. ► Binder enhances the relative density and the mechanical strength of sintered samples. ► The properties of samples containing PVA are better when the amount of PVA is lower. ► We note a good sintering and densification of samples prepared with PEG binder.
