摘要
The study of controlling the pore size distribution of silica aerogel powder was discussed for the first time.The pore repairing method endows the silica aerogel powder with uniform pore structure.The pore structure in the gel particles were uniform within just 2 h of aging.The thermal conductivities experiences were decreased from 0.0301 W/m·k to 0.0243 W/m·k, which is attributed to the macropore reduced.
