Measured values for Calcium carbonate, and where each one comes from
18 measured values for 7 properties, read from 4 public databases. On 1 property the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
2 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- 1517-2442 °F (Decomposes)
- NIOSH Pocket Guide
- 1517-2442 °F (decomposes)
- OSHA Occupational Chemical Database
Vapour pressure
2 records agree
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 0 mmHg (approx)
- NIOSH Pocket Guide
- 0 mmHg (approx)
- OSHA Occupational Chemical Database
Density
4 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- Bulk density: 40-100 lb/cubic ft; screen analysis: usually 200 to 325 mesh
- Hazardous Substances Data Bank (HSDB)
- 2.7-2.95
- NIOSH Pocket Guide
Solubility
7 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Solubility Product constant: 3.36X10-9 at 25 °C

pH
1 record
Drives the skin and eye corrosion classification for solutions, alongside the corrosivity data.
- pH = 8 to 9
- Hazardous Substances Data Bank (HSDB)
Odour
1 record
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
Decomposition temperature
1 record
The temperature at which the substance breaks down, often into products more hazardous than itself.
- At about 825 °C it decomposes into calcium oxide and carbon dioxide
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Calcium carbonate, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
