Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]
Californium(IV) oxide (CfO 2) is a black-brown solid that has a cubic crystal structure with a lattice parameter, the distance between unit cells in the crystal, of 531.0 ± 0.2 pm. [7]

Californium polyborate is a covalent compound with formula Cf[B 6 O 8 (OH) 5]. In this compound the californium is in a +3 oxidation state. This compound is the highest atomic number borate with a visible solid phase. Heavier elements than californium decay too fast to make macroscopic amounts of solid crystals. [1]
