Ikaite is the mineral name for the hexahydrate of calcium carbonate, CaCO3·6H2O. Ikaite tends to form very steep or spiky pyramidal crystals, often radially arranged, of varied sizes from …

Dec 17, 2022 · Calcium carbonate hexahydrate (ikaite) is a rare mineral that forms as metastable species in the organic-carbon-rich sediments of the King George Basin, Bransfield Strait, …

May 18, 2020 · We found that ikaite precipitated at temperatures of at least 35 °C at pH 9.3 −10.3 from a mixture of natural seawater and sodium carbonate rich solution. At pH 9.3, we …

Ikaite – the icy version of calcium carbonate from Antarctica Link Natural Ikaite Link. Calcium carbonate can crystallize in a hydrated form as ikaite at low temperatures. The hydration water …

Dec 19, 2012 · Ikaite (CaCO 3 · 6H 2 O) is a monoclinic carbonate that is metastable at temperatures approximately above 4°C (for stability conditions at high pressure, see Marland, …

Ikaite is the mineral name for the hexahydrate of calcium carbonate, CaCO3·6H2O. Ikaite is colorless when pure. It is usually considered a rare mineral, but this is likely due to difficulty in …

Oct 1, 2022 · Ikaite is a rare, metastable form of hydrated calcium carbonate (CaCO 3 ·6H 2 O) that may be synthesised under certain physical and chemical conditions, and is found naturally …

Apr 1, 2022 · Ikaite was first discovered as a synthetic laboratory mineral by the French chemist Pelouze (1865), who correctly identified it as a phase of calcium carbonate.

Ikaite is a rare mineral that is chemically identical to calcite, but has a different crystal form which contains water in its structure. It is found naturally growing in places that are characterized by …

Glendonites are pseudomorphs after the mineral ikaite, a monoclinic mineral with composition CaCO 3 ·6H 2 O. Ikaite forms in near-freezing waters. It requires pressures exceeding those …
