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 ...

Structural features of phosphate and sulfate modified zirconia prepared by sol-gel route
(Springer, 2004-10-01)
This paper describes the effect of sulfate, phosphate and nitrate complexing ligands on the structural features of amorphous xerogels and on the crystallization of metastable zirconia phases during the xerogel-ceramic ...

Structure-mechanical properties of heat-induced whey protein/cassava starch gels
(WILEY-BLACKWELL, 1997)
Structure-mechanical properties of heat-induced whey protein isolate/cassava starch (WPI/CS) gels were studied by hot-stage video microscopy (HSVM) and axial compression testing (ACT). Elastic moduli (or compression stress) ...
Morphological characterization of aqueous tin oxyhydroxide gel
(1994-05-01)
Light scattering, electron microscopy and X-ray diffraction are used to determine the morphology and size of particles in diluted aqueous gel of tin (IV) oxyhydroxide. Data show that the gel is composed of spherical 2-3 ...
