,Beschreibung des Führungsansatzes, stability. A schematic representation of the sheet structure is given. Furthermore, the crystallization has been studied and characterized by means of physical and chemical methods depending on the types and the amounts of the polymeric cation and the addition of alumina.

Jens Mergenthaler,Werner G. Faixompounds calcined in a vacuum up to 1000°C keep the high surface area and show peculiar electron spin resonance (ESR) centers on adsorption of oxygen, which are attributed to the formation of silicon dangling bonds. The ESR centers disappear reversibly on desorption of oxygen.

Modellentwicklung und Hypothesen,nter cations, mainly alkali and alkali earth ions, were observed. By adjusting the pH and temperature, hollandites could be synthesized with a counter cation which has an ionic diameter between 2.3 and 4.6 Å. Otherwise, nsutite and pyrolusite would be formed.

Anionic Clays: Trends in Pillaring Chemistry, nomenclature. Anionic clay minerals are relatively rare and are often associated with serpentinites in metamorphic formations . These minerals also occur in saline deposits which shows that high temperature and pressure conditions are not absolutely necessary for their genesis.
