Description of key information

Zirconium dinitrate oxide is a white solid, under ambient conditions (Younis, 2015a, key study, Klimisch 1).

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

A GLP-compliant experimental study of reliability 1 according to Klimisch, dealing with relative density but reporting description of the registered substance, was selected as a key study (Younis, 2015a). The test item is described as a white solid.

Although the reference substance is a solid, the substance is also available and used as aqueous solution. Therefore, a supporting study was added (SDS MEL Chemicals, Klimisch 2) reporting on the appearance of a representative aqueous solution of the reference substance. The aqueous solution was yellow, and had a slight odour, at ambient temperature.
