POROUS CERAMIC MOLDED GOODS

摘要

PROBLEM TO BE SOLVED: To provide porous ceramic molded goods whose transpiration performance is optionally adjusted for matching the kind of a transpiration device and the property of a liquid chemical, for example, and which are used suitably for a liquid sucking core of a suction type thermal transpiration device. SOLUTION: The porous ceramic molded goods are constituted of powder of a silica-based ceramic raw material as a principal component and have 5-30 volume % pipe-shaped pores having 3 or larger aspect ratio and 10-30 volume % almost square pores.
