Abstract: Provided is a method for manufacturing porous ceramics with thermal conductivity anisotropy and ordered pore arrays by arrangement of crystalline graphite added to ceramics through multi-stage pressing. The thermally conductive-anisotropic porous ceramics are manufactured by the following steps of: mixing ceramic powder with 5-80vol%(based on the volume of ceramics) of crystalline graphite having a 100-500micrometer size and a plate shape; pressing mixed ceramic powder under pressure of 0.1-0.7ton/cm2 through multi-stages(1-20stages) to maximize the arrangement of graphite, wherein the anisotropic thermal conductivity is increased as the pressing is repeated, and pressing through several times arrays planar pores in a direction perpendicular to the pressing direction; calcining pressed ceramics at 800-900deg.C to remove crystalline graphite; sintering ceramic preforms at 1450-1650deg.C. The resultant anisotropic porous ceramics are used as heat insulating materials and make conventional refractories light and small in weight and size.
