>40d:Cobaltite
Cobaltite is a brilliant blue stone (notably, the only stone of its color) found as veins in numerous environments. Despite its appearance (showing up as £ unmined and * mined), it is not a usable ore.. Cobaltite is particularly dense, making it potentially useful for stone-fall traps and as catapult ammunition (all heavier stones have notable economic uses).

>Gemstone, Properties, Occurrence, Uses
Cobaltocalcite is a captivating and visually distinctive mineral that belongs to the calcite group of minerals. It is renowned for its remarkable pink to peach coloration, which sets it apart from the more common white or colorless calcite crystals. This unique hue is a result of the presence of cobalt within its chemical composition.
>Topotactic synthesis of highly-textured thermoelectric cobaltites
For high-temperature thermoelectric power generators, single-crystal-like polycrystals of misfit-layered cobaltites were fabricated using an in situ topotactic conversion of aligned "reactive seed" platelet particles and the highly textured ceramics exhibited strong anisotropy with improved electrical conductivity.

>X-Ray Spectroscopy of Cobaltites
A classic example of cobaltites with a low-spin configuration of cobalt ions is lithium cobaltite LiCoO 2 that is a well-known material for power source cathodes. The nature of holes in defective cobaltites of the Li x CoO 2 (x < 1) type is considered. It is shown that holes arising from defects in the lithium sublattice are of an oxygen nature.

Tailoring Oxygen Content on PrBaCo2O5+δ Layered Cobaltites
The LnBaCo2O5+δ cobaltites with ordered A-site cations exhibit a very rich phase diagram as a function of the oxygen content, which determines the doping of CoO2 planes. By means of thermogravimetry analysis (TGA), we study the appropriate way to tailor oxygen contents in PrBaCo2O5+δ compounds. Starting from an air-synthesized sample, we study the …
