| 摘 要： | 采用注浆成型的方法制备硅藻土多孔陶瓷，对不同温度烧结样品的耐酸、碱腐蚀性进行了研究。材料的耐酸蚀性优于耐碱蚀性。硅藻土多孔陶瓷经过酸或碱处理后，微观结构和宏观性能会发生相应变化，也可利用这一特性通过酸或碱处理来控制瓷的微结构和过滤性能，碱处理样品、酸处理样和原始样品的氮气通量分别为1189、802和677m^3m^-2h^-1bar^-1。 |
| 关 键 词： | 硅藻土 多孔陶瓷 耐腐蚀性 通量 |

| Abstract: | Porous ceramics was fabricated from diatomite by means of slip casting, and the stain resistance for different sintering temperature was investigated. The resistance to acid is better than that to alkaline, microstructure and macro-performance of the ceramic varies correspondingly after acid or alkali treatment. The nitrogen flux for alkali treatment, acid treatment and original sample is 1 189, 802 and 677 m^3m^-2h^-1bar^-1 respectively. |
| Keywords: | diatomite porous ceramics stain resistance flux |
