- 概要:
- Changes in the structure and permeability of porous magnesia ceramic with a TiO_2-Al_2O_3 matrix with a TiO_21Al_2O_3 molar ratio of 0.96 were studied at different matrix contents. The shape of pores became complicated and pores tended to have fractal nature as the matrix content increased. It was proposed that the change of pore shape was caused by the increase in the amount of the matrix and its reaction with MgO grains. Both mean pore diameter and … permeability showed a maximum at a matrix content, 10 wt% and 15%, respectively. On the other hand, the fractal dimension of pore shape changed from 1.39 at 5 wt% to 1.65 at 20 wt% of matrix. The fractal dimension changed sharply between 10-15 wt%. The permeability was found to agree well with that of a nonspherical particle system by using pore size modified by the its fractal dimension. 続きを見る
