Monolithic diphasic gels of mullite by sol-gel process under ultrasound stimulation
(1998-12-01)
Diphasic gel in the mullite composition was prepared from a colloidal sol of boehmite mixed with a hydrolyzed tetraethoxisilane (TEOS) solution. The boehmite sol was obtained by peptization of a poorly crystallized or very ...

O processo sol-gel: uma visão físico-química
(Soc Brasileira Quimica, 1995-03-01)
The aim of this work was to revise the main concepts involved in the physical-chemistry of the sol-gel process. First, the preparation and its influence on the gel's structure are focalized; the sol-gel transition is revised ...

Pore size distribution of unsupported SnO2 membranes prepared by sol-gel process - Code: EP21
(1994-01-01)
Unsupported SnO2 membranes were prepared by sol-gel process and characterized by N2 adsorption-desorption isotherms and X-ray diffraction. Results show that the texture of dried samples does not change appreciably with the ...
