Preparation of SiO_2 Aerogel by Rice Husk
Source abstract
Abstract
A SiO_2 aerogel was prepared with rice husk, being cooked in boiling solution of diluent hydrochloric acid, then dried, and then pyrolyzed. The results show that the SiO2 mass content in aerogel is 99.99%, the average particle size is 20.77μm, and the specific surface area is 251m2/g determined by ICP-AES, particle size analyzer and surface area pore size analyzer respectively. The structure transformation of rice husk during the aerogel preparation was investigated by XRD, IR and SEM.
