Californium(IV) oxide is a binary inorganic compound of californium and oxygen with the 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 pm. Crystals of californium(III) oxide normally have a body-centered cubic symmetry. They convert to a monoclinic form upon heating to about 1400 °C and melt at 1750 °C.[3]
