| Abstract: | The study is on synthesis of mullite whiskers by sol-gel method,using industrial alumina sol and silica sol as raw materials.The effects of different acids on gelatification and formation of mullite whiskers were studied.When using citric acid to adjust pH value of the system,the time of gelatification could be reduced,as well as the mullite whiskers with good appearance and high aspect ratio were obtained. |
