Curium is named after Madame Curie and her husband Pierre Curie
Crystal Structure
Simple Hexagonal
Tarix
Curium was discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso in 1944 at the University of California, Berkeley.
It was produced by bombarding plutonium with alpha particles during the Manhattan Project.
Curium metal was produced only in 1951 by reduction of curium fluoride with barium.

Applications
Curium is mainly used for scientific research purposes.
Curium is a common starting material for the production of higher transuranic elements and transactinides.
The most practical application of 244Cm is as α-particle source in the alpha particle X-ray spectrometers (APXS).
