The blue mineral pigment aerinite studied at high temperature with laboratory powder diffraction datas (466 words)
The structure of aerinite, a blue fibrous silicate mineral associated with the alteration of ophitic rocks in the southern Pyrenees has been recently determined by applying the direct methods modulus sum function to synchrotron powder diffraction data [1].
The crystal structure of aerinite can be best understood by introducing cylindrical basic building units consisting on three pyroxene chains pointing inwards to accomodate tri- and divalent cations at the centre of the resulting face-sharing octahedra.
One peculiar property of aerinite that has been confirmed by infrared spectroscopy and TG measurements, is the loss of the CO groups when heated at 300ºC. When cooled down, however, aerinite slowly absorbs CO from the atmorsphere and, at the end, the resulting structure is identical to the initial one.
Trinity Mineral Co - The Sainte-Marie-aux-Mines Show (164 words)
The blue is caused by inclusions of aerinite - a bluish colored mineral with the chemical formula:
9 x 5.5 cm specimen with crystals of quartz heavily included with aerinite.
7.5 x 3 cm specimen with crystals of quartz heavily included with aerinite.
