Plastic Deformation of Nano-TiO2 Ceramics Prepared by Different Methods

The comparative study of the tensile plastic deformation of nano(n)-TiO2 ceramic prepared by physical gas condensation (P) and chemical hydrolysis precipitation (C) methods was conducted by a gas pressure forming technique at 750-800℃. The results show that n-TiO2 (P) possesses excellent property of tensile plastic deformation comparing with n-TiO2(C). The reason for this is attributed to the surface cleanness and soft agglomeration of n-TiO2(P) particle prepared in relatively clean vacuum condition.
