| 多孔陶瓷材料基本内容 Basic contents of porous ceramic materials (1)气孔率高。多孔陶瓷的重要特征是具有中较多的均匀可控的气孔。气孔有开口气孔和闭口气孔之分，开口气孔具有过滤、吸收、吸附、消除回声等作用，而闭口气孔则有利于阻隔热量、声音以及液体与固体微粒传递。(2)强度高。多孔陶瓷材料一般由金属氧化物、二氧化硅、碳化硅等经过高温煅烧而成，这些材料本身具有较高的强度。 (1) The porosity is high. The important characteristic of porous ceramics is that there are more uniform and controllable pores in porous ceramics. The open pores have the functions of filtration, absorption, absorption and elimination of echo, while the closed pores are beneficial to block the heat, sound and the transfer of liquid and solid particles. (2) High strength. Porous ceramic materials are usually made of metal oxides, silicon dioxide, silicon carbide and so on, which have high strength. |
