vaskkarbonaathüdroksiidi

Vaskkarbonaathi-hydroksiidi, also known as iron(II) hydroxycarbonate, is a chemical compound with the formula FeCO3(OH). It is a rare mineral species, first described in 1960 from a meteorite.

The mineral has a nepheline-like structure, with iron and carbon present in a ratio of 1:1. The hydroxyl (OH) group is present as part of a bicarbonate (HCO3) unit, making it distinct from similar carboironates.

Vaskkarbonaathi-hydroksiidi is typically found in association with other iron and calcium minerals in meteorites. Its appearance is often described as pale blue or blue-green due to its optical properties. It exhibits anisotropic behavior, meaning its optical properties differ depending on the angle of observation.

Chemically, the compound is relatively stable, with a resistance to thermal changes up to 100 degrees Celsius. It can be synthesized through the reaction of iron(II) oxide and a solution of sodium bicarbonate.

Some notable properties of vaskkarbonaathi-hydroksiidi include its relatively small size and crystalline structure, which displays a combination of bipyramidal and orthorhombic morphology. While it has some scientific interest, due to its rarity and parallels with other minerals and compounds.
