摘要：

The sintering behavior of TiO2 under high-pressure gas (100 MPa) was studied with respect to densification rate, decreasing rate of specific surface area, and narrowing rate of pore size distribution. At the low sintering temperature (800 degrees C) used in this study, the densification rate under high-pressure gas was similar to that under low (i.e., 1 atm) pressure. The specific surface area decreased and the pore size distribution narrowed at a faster rate Binder high-pressure gas than under low-pressure gas. These results imply that high-pressure gas enhances surface diffusion.
