氧化铝气凝胶的合成与性能
Synthesis and Property of Alumina Aerogel
摘要
Abstract
Alumina aerogel has wide application prospect in high temperature thermal insulation and catalytic fields due to its high specific surface area, high porosity, and better thermal stability than silica aerogel. However, the complicated synthetic process and the low strength of alumina aerogel restrict their application. In this review, the synthetic process of alumina aerogel is firstly introduced. Some problems existed in the Sol-Gel process, the characteristics of various drying methods, and the latest drying methods developed by researchers are pointed out. Then, some representation achievements in the performance improvements on specific surface area, thermal stabil-ity, thermal conductivity and compressive strength of alumina aerogel in recent years are summarized. Finally, the development and application of alumina aerogel in high temperature catalytic and thermal insulation fields are in-troduced, their development tendency is prospected, and some issues on the study of alumina aerogel are high-lighted.关键词
