TL;DR: Kamacite is a main entry in the 外星矿物知识引擎 database.
Kamacite is the low-nickel phase of the iron-nickel alloy system found in metallic asteroids. Unlike oxide ores, kamacite is already metallic and can be directly processed into structural materials. It is the primary economic target for asteroid mining of M-type bodies.
Formula
Fe₀.₉Ni₀.₁ (approximate)
Crystal System
Cubic (body-centered)
Occurrence
Major phase in iron meteorites and M-type asteroids; found in lunar regolith as meteoritic contamination
Significance
Direct source of metallic iron and nickel; no smelting required; primary target of asteroid mining
Source
Iron meteorite analysis, Psyche mission spectroscopy
