| ABSTRACT |
|
This study deals with the porous sintered body which is obtained by blending solid naphthalene with fine particles of Hwasun flint clay. Apparent porosity is increased, and bulk density, thermal conductivity, strength and thermal expansion are decreased according to the additiion of naphthalene. Pore shape of sintered body showed elliptical form and median size and capilary percentage are increased by adding more naphthalene. |
