Pigment Compendium: Optical Microscopy of Historical Pigments
Crystallinity n Cubic Synthetic antimony oxide, senarmontite type can be seen in
planepolarised light to form colourless transparent particles with moderate relief
and RI greater than that of the medium. Grain size ranges from fine to very fine ...

SENARMONTITE White Generic compound Senarmontite is a cubic antimony
oxide mineral with composition -Sb2O3. It forms as soft white or grey octahedral
crystals which fracture conchoidally, although granular or encrusting forms may
be ...
Valentine Walsh, Tracey Chaplin, 2008
The usual raw material was the antimony sulfide mineral stibnite (q.v.), which was
roasted in air to form the oxide (Merck Index, 1996). Several structural
modifications exist, notably the minerals valentinite and senarmontite, along with
their ...

Handbook Of Fillers For Plastics
Manufactured antimony trioxide has two crystalline forms: senarmontite, a cubic
crystal, and valentinite, a rhombic crystal. Antimony trioxide vapor condensed
above 570°C contains mostly valentinite. Senarmontite is formed at the lower ...

Economic Geology: Principles and Practice
These include native antimony and a number of sulphides, sulphosalts, oxides,
antimonates and antimonites. Weathering of primary antimony minerals produces
grey-coloured ochres and greyish-white senarmontite. Antimony ore is often a ...

With senarmontite the saturation point is not reached in the same period.
Valentinite therefore possesses the greater rate of dissolution in acid solution.
The relationship is different in alkaline solution. Here a smaller dissolution effect
can only ...

Valentinite crystallizes in the rhombic system (2mm), and senarmontite in the
cubic system (m3m). This paper deals with the preparation of single crystals of
valentinite and senarmontite under hydrothermal conditions. These single
crystals ...
