Study of the dehydroxylation-rehydroxylation of pyrophyllite
(American Ceramic Society, 2010)
Pyrophyllite is a raw material of significant interest due to its large number of applications. Most of these applications require a thermal transformation of pyrophyllite; this thermal transformation implies the release ...
