About Kamacite Hide. From the Greek "kamask" meaning "shaft" or "lath". A variety of Iron A nickel-rich variety of iron;
α - (Fe,Ni). The principle constituent of a typical octahedrite meteorite with about 92% iron and 7% nickel. Compare also taenite,γ - (Ni,Fe).Kamacite | Iron-Nickel Alloy, Octahedrite, Meteorite | Britannica
Kamacite, mineral consisting of iron alloyed with 5–7 percent nickel by weight and found in almost all meteorites which contain nickel-iron metal. It has a body-centred cubic structure and is sometimes referred to as
α iron, after one of the three temperature-dependent forms (allotropes) of …Kamacite Mineral Data
Empirical Formula: Fe 0+0.9 Ni 0.1. Environment: Major constituent of iron meteorites. Kamasite (1861) fails the 50% rule so it is a Ni-rich iron. IMA Status: Discredited IMA 2006 - Valid Species (Pre-IMA) 1861. Locality: Disko Island, Uivfaq, Blaafjeld, …

α –(Fe, Ni) Crystal Data: Cubic. Point Group: 4/m 3 2/m. As plates and lamellar masses and in regular intergrowth with taenite. May occur in crystals, to 30 cm; in extended plates and ribbons in Widmanst ̈atten bands.Kamacite and Taenite - Steve Dutch
Kamacite and Taenite are the principal iron-nickel alloy minerals in iron meteorites. Taenite is the nickel-rich phase (mnemonic: Taenite contains "ni") with 30 to 70 per cent nickel. Kamacite is the iron rich phase with generally 5-10 per cent nickel.
Kamacite
Kamacite is a metallic alloy of iron and nickel found only in meteorites. It has a metallic luster, a density of about 8 g/cm³, and a hardness of 4 on the Mohs scale. Kamacite is considered a nickel-rich variety of native iron and is a major constituent of iron meteorites.
Kamacite
SEM image of typical Nickeloan Iron (var. Kamacite) drops sprayed over surface of Lunar regolith particle, composed by an impact glass. These nickeloan iron drops were formed during meteorite impact, when metal of the initial meteorite was evaporated and then condensed within a flow of spreading gases during an explosion.
Kamacite - an overview | ScienceDirect Topics
Kamacite is a metallic phase found in iron meteorites, characterized by its formation of lamellae with a nickel content of less than 6%. It is part of the Widmanstätten pattern, which gives the iron meteorite its octahedral structure.
