POROUS CERAMIC AND METHOD FOR PRODUCING SAME

The porous ceramic comprises a loose layer and a compact layer, the surface of the loose layer is a seepage surface, the surface of the compact layer is an atomization surface, a plurality of finger-shaped holes extending in the vertical direction are formed in the loose layer, the hole diameter of the finger-shaped holes is decreased on the side close to the seepage surface, and the finger-shaped holes do not penetrate through the compact layer downwards. A plurality of capillary holes are further formed in the loose layer and the compact layer, the hole diameter of the capillary holes is smaller than that of the finger-shaped holes, the capillary holes are communicated with one another and are communicated with the finger-shaped holes, the thickness of the loose layer is larger than that of the compact layer, and atomized liquid permeates into the porous ceramic from the seepage surface. The invention further discloses a manufacturing method of the porous ceramic. 一种多孔陶瓷，包括疏松层与致密层，所述疏松层表面为渗液面，所述致密层表面为雾化面，所述
