Hello Researchers and friends,
I have a conduct research to make a super insulation blocks. I have an admixture of Silica aerogel powder need to be added to the cement in order to manufacture blocks. My question is how do I get to mix experimentally the admixture of Hydrophobic Silica Aerogel Powder with cement ?
Kind Regards,
Layth
Silica-Alumina mixed oxide aerogels through non-supercritical drying using boehmite
as a precursor for alumina is to be synthesised. During the preparation of mixed oxide
aerogels involving silica, if the hydrolysis of the metal alkoxide is faster than that of
silicon alkoxide, a non uniform sol results because sedimentation takes place before
gelation. So we have to choose boehmite (Condea, Germany) sol as one of the precursors for the preparation of silica alumina aerogels and hybrid sol-gel route ensures nanometric scale mixing in heterogeneous systems. The percentage of alumina in the silica matrix is to be varied and the gels are to be calcined at various temperatures to study the thermal pore stability...
