摘　　要：空心玻璃微球作为一种新型高性能粉末材料,特殊的球形空心结构使其在低温绝热领域有很好的应用前景。文章综述了空心玻璃微球与珠光砂、气凝胶等粉末绝热材料和真空多层材料以及单纯高真空的低温绝热性能对比研究,并进一步综述了空心玻璃微球本身性能变化和金属包覆对其低温绝热性能的影响研究。另外,还介绍了微球绝热系统在1 000 L、22 700 L和218 000 L储罐中的实际应用情况。As a high performance powder material,hollow glass microspheres have a very good application prospect in cryogenic insulation for its special hollow spherical structure. The research on cryogenic thermal performance compari-son between hollow glass microspheres and aerogel beads,perlite powder,vacuum multi-layer insulation material and vac-uum only was summarized in this paper. Research on cryogenic thermal performance of coated microspheres and the per-formance of the bubbles itself was also summarized in this paper. What’ s more,the application of microsphere insulation system on cryogenic tanks of 1 000 L,22 700 L and 218 000 L was briefly introduced.
