| Summary: | 碩士 === 國立成功大學 === 資源工程學系 === 88 === Studies tried to improve the pore configuration of dolomitic ceramics by adding NaCl particles were made. NaCl particles were used as the solid pore forming agents. After treated with different sintering times and temperatures for the ceramics, the best condition and if it had the possibility for the ceramics to be the substrate of alumina membrane were determined.
It is found that ：
1. Samples sintered at 1150 and 1100 ℃ for 3 and 2 hours, respectively with NaCl particles additions would have the values of specific flow rate of gas improve 7~8 times, compared with the original ceramics.
2. SEM examinations revealed that bonding between the alumina membrane and the substrate was well - developed. But it still had the problem of CaAl4O7 formation which tends to hydrate if contacted with water.
