Besides dispersity and morphology, structural characteristics are of importance for the estimation of amorphous synthetic silicic acids with regard to their application. The present publication shows that it is possible to identify the different silicic acid types on the basis of thermoanalytical studies. The TG and DTA results provide information on the type and quantity of adsorbed or chemically bound water, and on the oxidative decomposition of the organic coating agent.
