摘要：

The morphological change of natural pores with densification was examined in an alumina green body. The liquid-immersion technique was used for observing pores inside the body before and after sintering. In this technique the specimen is made transparent by an adequate immersion liquid and observed with a transmission optical microscope. Growth of large pores with densification was observed and is discussed along with past thermodynamic consideration of pore growth. Supplemental investigation of the results was conducted by SEM and mercury porosimetry.
