Test material
- Reference substance name:
- Iron silicate, copper smelting and refining
- EC Number:
- 701-480-0
- Cas Number:
- 67711-92-6
- IUPAC Name:
- Iron silicate, copper smelting and refining
- Details on test material:
- Melting point was tested on two representative sample types :
Type I: Slag, Granules, Primary ( Sample 09TT02641)
Type III: Slag, Slow cooled, primary ( Sample 09TT05244)
Due to differences in crystalization during slag cooling ( rapid coolig /granulation or slow cooling) and silacate phases formed an effect on melting point is expected.
Sampling and sample preparation was performed according to ECI/REACH C1 Sampling Protocol. The C1 sampling protocol also provides detailed information on the identity of the samples (see IUCLID section 1.4).

Any other information on results incl. tables
During the TG/DSC tests the sample was heated in Al2O3crucible using nitrogen atmosphere and air atmosphere.
Sample Type I (09TT02641)
No endothermic peaks were found during the test in nitrogen atmosphere. The test in air atmosphereshowed endothermic peaks at the temperature ranges 1341 – 1360 °C and 1412 – 1429 °C. These peaks indicate melting.
Sample Type III (09TT05244)
No endothermic peaks were found during the test in nitrogen atmosphere. The test in air atmosphere showed endothermic peak at the temperature range 1027 – 1043 °C, which indicates melting. The mass of the sample starts to decrease at the temperature ~1150 °C, which indicate some decomposition and evaporation.
