Production of silica gel from residual rice husk ash
(Sociedade Brasileira de Química, 2011)
This paper presents a study on the production of silica gel in hydrothermal process using residual rice husk ash. Measurements of the chemical composition, X-ray diffraction, infrared spectroscopy, particle size distribution, ...
A kinetic study of drying of TEOS-derived gels under nearly isothermal conditions
(ABM, ABC, ABPol, 1999-01)
The drying of wet Tetraethoxysilane-derived gels was studied by means of thermogravimetric analysis as a function of the time, from the instant when the samples were placed into a pre-heated oven, kept at 70, 83 and 100 ...
