Silica Aerogel Santocel

In recent years the increasing use of liquefied gases in industry, as rocket propellants, and as low-temperature baths, to mention only a few. and the practical results of transporting gases in liquid form, have necessitated a search for more efficient schemes for low-temperature insulation. Evacuated powders are one scheme that shows promise. Powder insulation, in either evacuated or unevacuated systems, refers to the use of materials with a low bulk solid conduction, in a finely divided state. Examples are silica aerogel (Santocel, Cab-0-Sil,Syloid), calcium silicate (Microcel), diatomaceous earths, perlite, etc. 

Santocel C is a silica aerogel produced by Monsanto Chemical Company. Its silica content is approximately 96% on the dry basis, and its impurities include small percentages of Na2S04, A1203, and FejOj.

Four silica samples, Aerogel S, Santocel C, a Davison xerogel, and Linde silica have been subjected to vacuum sintering treatments.
