Californium(IV) oxide, also called californium dioxide, is a binary actinide inorganic compound of californium and oxygen with the chemical formula CfO
_². ^[1]

Synthesis

Californium dioxide is produced by oxidizing californium with molecular and atomic oxygen at high pressure. ^[2]

Physical properties

Californium(IV) oxide is a Black-brown solid that has a cubic fluorite crystal structure with a lattice parameter, the distance between unit cells in the crystal, of 531.0 ± 0.2 picometers (pm) (530.8 - 531.2). ^[3]

Health Hazards

Californium Dioxide accumulates in the bone and liver and is a potent alpha emitter, and due to its radioactivity, it can cause various cancers. ^[4] While it may not be as radioactive as pure Californium-252, it is still highly radioactive as Californium, Californium makes up 33.333% of the compound (66.666% Oxygen).
