taenite (plural taenites)
(mineralogy) A mineral, found in certain meteorites, that is a magnetic alloy of iron and nickel
As the meteorite cools and taenite and kamacite are sorting out of each other some of the trace elements will prefer to be located in taenite or kamacite. Source: Internet
For kamacite, the alloy is usually in the proportion of 90:10 to 95:5, although impurities (such as cobalt or carbon ) may be present, while for taenite the nickel content is between 20% and 65%. Source: Internet
Likewise if the meteorite is dominated by the face centered taenite it is called an octahedrite as kamacite will exsolve from the octahedral crystal boundaries of taenite making the meteorite appear octahedral. Source: Internet
Kamacite and taenite are naturally occurring alloys of iron and nickel. Source: Internet
Kamacite forms taenite as it forms and expels nickle to the sourounding area, this area forms taenite. Source: Internet
The increase in nickel content causes taenite to have a face-centered unit cell, whereas kamacite’s higher iron content causes its unit cell to be body centered. Source: Internet
