Description of key information
Bulk calcium carbonate is a fine white powder which tends to form clumps, at 20 ± 0.5 °C.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
The appearance of bulk calcium carbonate is based on a GLP study (Walker and White, 2010). This result is supported by data from several peer reviewed handbooks.
