POROUS BODY MADE OF A VITREOUS AND/OR GLASS-CERAMIC SINTERED MATERIAL AND ITS PROCESS OF MANUFACTURE

摘要

the porous sintered body mould comprises at least 90% of the pores are open pores, they communicate with each other and with the atmosphere.these pores are equal and the distribution of pore diametres is the same in all directions.the material is a sintered glassy and crystalline and / or ceramics and presented a coefficient of thermal expansion.for the manufacture of such body is sinterable material (mixing finely divided with an organic material, through a mold.the organic material is sintered and oil material.
