Alumina Aerogel. Alumina aerogels possess the characters of low density hightemperature stability high porosity and highsurface area and exhibit better performance in catalysis [1 2] and thermal insulation [] at the high temperature of 1000 °C and beyond than any other monomeric aerogelsThe sol–gel method using hydrated alumina salts (primarily AlCl 3 6H 2 O and Al(NO.

Preparation and characterization of monolithic alumina
The incorporation of alumina phase in the aerogels was performed through aluminium chloride (AlCl3) or aluminium trisecbutoxide (ATSB) precursors replacing a small part of Si (up to 15 mol%) by Al For system optimisation several parameters that could influence the key properties (bulk density thermal conductivity and thermal stability) of the aerogel were.
Nanoengineering Super HeatResistant, Strong Alumina Aerogels
Alumina aerogels are cool because they don’t sinter until about 950°C where silica aerogels sinter around 600°C You can actually increase their crystallinity by heat treating them in an oven at a temperature around 270°C for about 4 hrs and even at 1050°C they will only shrink about 2% Useful Information Aluminum tri sec butoxide.

The inexpensive boehmite sol was used as alumina source to prepare Al 2 O 3 SiO 2 aerogel • The partial sintering of aerogel during its preparation process endows the aerogel with high elastic modulus of 78 MPa • The carbon in silicon oxycarbide can act as a pore former by oxidizing with O 2 during preparation process •.
