| Summary: | 碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 107 === Three waste glasses and two in-house synthesized glasses, G11 glass and G17 glass (quaternary BaO–SiO2–B2O3–Al2O3 composition) are chosen. Those glasses combine with commercial castable refractory powder to meet the need of the thermos-insulation of intermediate-temperature SOFC. The castables perform appropriate four castable properties, shrinkage of 800-1000oC sintering, three-point bending strength of sintered test bars, thermal conductivity, and abrasion resistance. The game is set by two competitive players, and performs one-on-one strategy based on the game theory. The property performance of T2 samples finally gets improved. Three-point bending strength and erosion resistance of T2-2 and T2-3 samples were greatly improved. The linear change was less than 2.0% after heat treatment to 1000 oC, and thermal conductivity value of T2-2 containing SiC shows a higher value of 0.43±0.05 W/mK at 800 °C, and the value of GW-containing T2-3 sample is 0.28±0.02 W/mK. The reasons of the property improvements are discussed in this work.
