DRYING METHODS PRESERVING THE TEXTURAL PROPERTIES OF GELS

G. Pajonk 
Abstract : To preserve more or less the gels textural properties during their drying step three main methods can be applied which differ roughly by the temperature and pressure range in which they are conducted. In increasing temperatures and pressures ranking one may distinguish : i) the freeze drying process giving "cryogels" (low pressures and temperatures), ii) the ordinary drying method leading to xerogels (ordinary or low pressures and temperatures) and finally, iii) the supercritical drying method producing aerogels (high pressures and temperatures).
