摘要：

Bulk n-TiO2 samples with a relative density as high as 95% have been fabricated by means of hot-pressing at temperatures as low as 400 degrees C and at pressures up to 1.5 GPa. During hot-pressing, the anatase phase transformed to the rutile phase and the amount of the transformation increased with sintering pressure. We believe that the smaller grain size of the rutile phase compared with that of the pre-transformed anatase phase is related to multiple nucleation events in the anatase phase during sintering at very high pressure.
