| 内容記述 | TO DEVELOP A CERAMIC LINER,A SELECTION TEST OF MATERIALS,AN IMPROVEMENT TEST OFSELECTED MATERIAL,AND A FEASIBILITY TEST OF THE LINER HAVE BEEN CONDUCTED.IN THE SELECTION TEST,FIFTY COMMERCIALLY AVAILABLE HIGH TEMPERATURE CEMENT ANDCERAMICS WERE SUBJECTED TO THERMAL SHOCK TEST(TST),SODIUM EXPOSURE TEST(SET),ANDSODIUM FLAME EXPOSURE TEST(SFET). FROM TEST RESULTS,ALUMINA/SILICON-CARBIDE(AL2O3-SIC)MIXTURE BASE CASTABLE REFRACTORY WAS SELECTED IN CONSIDERATION OF MATERIAL COST,AND MATERIAL AVAILABILITY FOR A SIMPLER LINER CONSTRUCTION IN THE BUILDINGS.THE SELECTED MATERIAL WAS SUBJECTED TO THE IMPROVEMENT TEST. FROM THE TEST,PROPERWEIGHT FRACTIONS OF ADDITIVES SUCH AS ALUMINA CEMENT AND SILICA WERE DETERMINED.DRYING CONDITIONS WERE ALSO DETERMINED.FINALLY,A SODIUM BURNING PAN MADE OF CONCRETE WHOSE INNER SURFACES WERECOVERED WITH THE IMPROVED AL2O3-SIC BASE CASTABLE REFRACTORY WAS FABRICATED AND WASUSED FOR A SODIUM BURNING TEST.
