Experiments using silica aerogel powders have yielded positive results. produced from a glass of water and Tetraethylorthosilicate TEOS and ambient pressure desiccating within short time are presented in this work. a glass of water the acid catalyst was HCl, which was hydrolyzed in water. To put it another way to cut down on the amount of modification and preparation During this time, a new mechanical technical procedure was developed. Crushing and filtering were added, as well as a solvent. The process of exchange/surface modification can be completed quickly. in this manner in addition, we used a water glass. instead of the base catalyst NH3H2O It does, to some extent. Contaminants from entering the aerogels were avoided shown to have a significant impact on the chemical and physical characteristics of land-based aerogels. Due to this, when the water glass relative dilution is 4, aerogels develop as a base catalyst. Possesses an advanced mesoporous structure (mean pore size of 20 nm)and a high degree of hydrophobicity (contact angle of 152°). [ABSTRACT FROM AUTHOR] |
