In this article, several high-pressure researches on carbon nanotubes are reviewed after the brief introduction of nanotubes in carbon family. Direct transformation to nanocrystalline diamond from multiwalled carbon nanotubes makes it possible to synthesize a transparent sintered compact without any sintering additive. Result of room temperature compression of multiwalled nanotubes up to 50 GPa suggests strong durability of tubular structure and exhibits no interlayer interaction such as hexagonal diamond formation. Attempts to store high-pressure fluid into nanotubes are also described.
