Executive summary:

Information on the appearance of palladium monoxide is from a Klimisch 1 GLP compliant guideline experimental study. The statement on appearance is taken from a study on physico-chemical properties of this material, and is adequate for the assessment as the key study for this endpoint. Palladium monoxide is a drak grey powder.

Description of key information

Palladium monoxide (anhydrous) is a dark grey powder. 

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

The statement on appearance and physical state is taken from a Klimisch 1, GLP compliant, guideline experimental study for palladium monoxide (anhydrous). The statement on appearance is taken from a study on physico-chemical properties of the material, and is adequate for assessment as the key study for this endpoint (Tremain and Atwal 2011). Palladium monoxide (anhydrous) is a dark grey powder.

Supporting data are taken from Lide (2008), a reliable peer reviewed handbook. At 20°C and 1013.25 hPa palladium monoxide forms tetragonal green-black inorganic crystals. WHO (2002) is a reliable peer reviewed handbook and states that palladium monoxide is a black-green or amber solid.
