Small crystal zeolites ZSM-5 with sizes of 150-300 nm were synthesized using the colloidal silicate precursors as the silica source created by the acid-catalyzed hydrolysis of tetraethylorthosilicate with tetrapropyla...
Colloidal silica sol is formed by a novel hydrolyzing procedure of tetraethyl orthosilicate(TEOS) catalyzing with NH 3 ·H 2 O in aqueous mediums. Glycerol, combining with the hydrolyzed intermediates of TEOS...
The deposition of silicon dioxide by plasma enhanced chemical vapor deposition from tetraethylorthosilicate (TEOS) and H_2O has been studied.Silicon oxide with refractive index of 1453 has been obtained.Tests on the 5...
