About PalladiumHide

Formula:
(Pd,Pt)
Colour:
Whitish steel-gray
Lustre:
Metallic
Hardness:
4½ - 5
Specific Gravity:
11.9
Crystal System:
Isometric
Name:
William Hyde Wollaston named the element in 1802 after the asteroid Pallas 2 (which had been discovered two months earlier), which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas.
Platinum Group. Gold-Palladium Series, Palladium-Silver Series and Palladium-Platinum Series.

Natural Palladium always contains some Platinum.

(Pd,Cu) alloys, some with the approximate composition PdCu4, are reported by Kapsiotis et al. (2010).
