CERAMIC CRYOGENIC ENERGY-STORING MATERIAL OF RARE EARTH OXYSULFIDE, METHOD FOR PRODUCING THE SAME, AND CRYOGENETIC ENERGY-STORING TOOL FOR VERY LOW TEMPERATURE BY USING THE CRYOGENIC ENERGY-STORING MATERIAL |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a ceramic cryogenic energy-storing material hardly causing fine powder or the like even after a long-time continuous operation by incorporating the material into a refrigerator, easily heat-exchangeable with a working medium, and having a large specific heat. <P>SOLUTION: Granules of Gd<SB>2</SB>O<SB>2</SB>S is packed in a pipe of the Gd<SB>2</SB>O<SB>2</SB>S, and sintered. The granules are bound to each other, and the granules and the pipe are integrated by the shrinking power of the pipe at sintering. The pipe is formed into the porous one by molding the Gd<SB>2</SB>O<SB>2</SB>S with an organic material mixed therewith. <P>COPYRIGHT: (C)2004,JPO |
