Curium (III) hydroxide is a chemical compound of radioactive curium from the group of hydroxides .

Extraction and presentation

Curium (III) hydroxide can be obtained by reacting ammonia with curium ³⁺ salt solutions. It was portrayed as the first curium compound from a fallout in 1947.

properties

Curium (III) hydroxide is a colorless to yellowish solid that is very sparingly soluble in water. It has a hexagonal crystal structure of the uranium (III) chloride type with the space group P 6 ₃ / m (space group no. 176) . Due to the radioactivity of curium, the compound decomposes within a day. Template: room group / 176
