Lunar Geology: Minerals on the Moon - PERMANENT
Calcium oxides and calcium silies are not only useful for ceramics, but pure calcium metal is an excellent electrical conductor. Calcium metal is not used as a conductor on Earth simply because calcium burns spontaneously when it comes in contact with oxygen (much like the pure magnesium metal in camera flashbulbs).
