Californium (III) oxifluoride (CfOF) was prepared by hydrolysis of californium (III) fluoride (CfF ₃ ) at high temperatures. Like californium (IV) oxide (CfO ₂ ), it crystallizes in the cubic crystal system in the fluorite structure , with the oxygen and fluorine atoms being found in a random distribution on the anion positions. The lattice parameter is 556.1 ± 0.4 pm.

safety instructions

Classifications according to the CLP regulation are not available because they only include chemical hazard and play a completely subordinate role compared to the hazards based on radioactivity . The latter also only applies if the amount of substance involved is relevant.

Individual evidence

↑ The hazards emanating from radioactivity do not belong to the properties to be classified according to the GHS labeling. With regard to other hazards, this substance has either not yet been classified or a reliable and citable source has not yet been found.
