Resumo
Alpha-alumina is a ceramic material with applications as a biomaterial in
femoral prostheses and teeth. The study of the influence of the precursor powder on
the microstructure and mechanical properties of the alumina obtained is extremely
important for the use of the same as biomaterials. Other applications of alpha-alumina
industrially are in obtaining parts used at high temperatures and in chemically aggressive
environments. Alpha-alumina can be synthesized from different raw materials
resulting in ceramic products with different microstructures and consequently with
diverse mechanical resistance. The synthesis of alpha-alumina pieces obtained from
gamma-alumina powders was studied in order to verify the mechanical properties of
the sintered material. The addition of graphene oxide in the gamma-alumina powder
was also studied. To evaluate the mechanical strength of the obtained alpha-alumina
specimens and to correlate the mechanical resistance with the precursor used in
alpha-alumina synthesis it was used three -point bend strength testing.
