The Physical Properties Of Palladium

- May 28, 2018-

Palladium is a silver-white transition metal that is soft, has good ductility and plasticity, and can be forged, calendered and drawn. The bulk metallic palladium can absorb a large amount of hydrogen, causing the volume to swell significantly, become brittle and even break into pieces.

At room temperature, 1 volume of sponge palladium can absorb 900 volumes of hydrogen and 1 volume of colloidal palladium can absorb 1200 volumes of hydrogen. When heated to 40-50°C, most of the absorbed hydrogen is released and widely used as a gas reaction, especially a hydrogenation or dehydrogenation catalyst, and an alloy for a resistance wire, a watch, and the like can also be produced.
