Phase relations in the pseudoternary system CaO-CoO-Si02 have been established at 1323 K.Three quaternary oxides werefound to be stable: CaCoSi206 withclinopyroxene (Cpx), Ca2CoSi207 with melilite (Me...
Authigenic Chrysotile Formation in the Matrix of Quaternary Debris Flows, Northern Southland, New Zealand
Authigenesis Chrysotile Debris flow Pseudoboehmite Serpentine
2011/11/25
Abstract: Quaternary debris flows derived from ophiolite melange in northern Southland, New Zealand, are locally cemented and veined by cross-fiber and fine-grained chrysotile. Chrysotile was identifi...
Preparation and Electrical Properties of Quaternary Ammonium Montmorillonite-Polystyrene Complexes
Electrical properties Intercalation Montmorillonite Polystyrene Quaternary ammonium complexes

A Study on the Cation Exchange of [Co(NH3)6]3+ from H-Co (NH3)6-Vermiculite by Inorganic and Quaternary Ammonium Ions
[Co(NH3)6]3+ H-Co (NH3)6-Vermiculite Inorganic Quaternary Ammonium Ions
2012/2/15
The exchange of [Co(NH3)6] 3+ from its vermiculite complex has been carried out with a number of inorganic and alkyl quaternary ammonium ions of varying ionic sizes. The distribution and selectivity c...
