Description of key information
According to handbook data, strontium hydroxide (anhydrous) appears as colourless orthorhobic crystals at approx. 25°C. Strontium hydroxide (anhydrous) is hygroscopic.
According to handbook data strontium hydroxide octahydrate appears as a colourless, deliquesce crystals or white powder. According to the expert judgement of the contract laboratory strontium hydroxide octahyte is a solid, white powder.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, the description of strontium hydroxide could be regarded as valid.
The expert judgment from Smeykal (2010) is considered reliable without restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
