ETIMOLOGIA CUVÂNTULUI POLLUCITE
From Latin polluc-, stem of Pollux + -ite1; originally called pollux, alluding to Castor and Pollux, since it was associated with another mineral called castor or castorite.

Run products of pollucite contain compositional domains (as seen in back-
scatter electron micrographs), that diverge to about 15 mol%. Because of the
short run times of the experiments, London et al (1998) do not equate these
trends with ...

Detailed mineralogical characterization studies revealed that (i) pollucite is
mostly. either interlocked with or present as fine inclusions in the associated
gangue minerals and (ii) lithium is contributed mostly by spodumene and partly
by mica.

Radiation Source Use and Replacement: Abbreviated Version
Pollucite is known to be substantially less soluble in water than cesium chloride;
the naturally occurring mineral is the primary ore for cesium and requires a series
of acid-base reactions to extract the cesium. Further studies have shown that ...

Glass Ceramic Technology
It must be noted, however, that the mineral pollucite, CsAlSi2O6, demonstrates a
very high melting point above 1900°C. As a result, it exhibits better refractory
qualities than any other silicate. Furthermore, pollucite is isostructurally related to
...

Handbook of Lithium and Natural Calcium Chloride
The pollucite zone of the deposit was massive and had little apparent crystal
faces or other indication of grain size, although some cleavage planes indicated
crystals 15 cm or so in width. The pollucite was randomly honeycombed by veins
of ...
