Clays and clay minerals (National Conference on Clays and Clay Minerals), 1954
Hydrothermal techniques have been used to study the stability and transformations in vermiculite. Partial dehydration occurs first at 550° C and completely nonexpanding structures are obtained first at 650° C at 1,000 atmospheres water pressure. Above 350° C (and rapidly near 400° C) a transformation of the vermiculite to a “chlorite-like” phase takes ...

Clay minerals have been proposed as very useful materials for modulating drug delivery. These are the commonly used materials in pharmaceutical production both as inorganic carriers or active agents. We focused on the development of suitable long-acting material for local treatment of oral infection where clay minerals act as inorganic drug carriers ...

The Geology of Vermiculite Occurrences
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1961AbstractVermiculite occurrences can be divided into two major categories, those having macro-scopic and those having microscopic or clay vermiculite. This paper is concerned with the former. The macroscopic type of vermiculite deposits can be subdivided into four categories based on the host rock: (1) ultramafic and mafic; (2) gneiss and schist; (3 ...

MONTMORILLONITE is known to be capable of forming organic complexes of two kinds, one due to a cation-exchange reaction1 and the other to the interlamellar adsorption of complete molecules2,3. Halloysite has also been reported as giving complexes of the latter type2, and recently also vermiculite4,5. Using a typical vermiculite, complexes of both types
