| Research Abstract |
A porous ceramics with cylindrical pores can be fabricated by unidirectional solidification in hydrogen atmosphere. The pore morphologies, such as porosity, pores diameter and distribution of pores can be controlled by the experimental conditions, such as total pressure, hydrogen partial pressure and solidification rate. When silica component was added in feed rod, porous ceramics with high porosity was obtained. When magnesia was added in feed rod, porous ceramics with high porosity was obtained in 1%H_2 atmosphere. A glassy boundary phase was formed in the solidified sample during the unidirectional solidification when silica and calcia were added in feed rod and the compressive property of the sample was improved by the formation of the glassy phase.
