Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: ISO R528
Principles of method if other than guideline:
The specified method is used for determining the pyrometric cone equivalent (refractoriness) of siliceous, low alumina fireclay and fireclay
refractory materials and products. Its usefull range of application depends on the availability of suitable pyromeric reference cones. It may also be
used for roughly determining the refractoriness of other refractory materials. The pyrometric cone equivalent of the test material is expressed by the number or numbers of the pyrometric reference cone or cones.

Details on test material:
- Name of test material (as cited in study report): Ciment Fondu®
- Substance type: mineral
- Physical state: dark grey fine powder
- Composition of test material, percentage of components: Ciment Fondu® is a mixture of more than 99.5% milled clinker of Ciment Fondu® which is the same substance as the registered substance here, and a grinding agent

Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 1 250 °C
Remarks on result:
other: 1250 °C represents the refractoriness of this substance.

Any other information on results incl. tables

the refractoriness of this substance was measured as 1250 °C.

Applicant's summary and conclusion

Conclusions:
The refractoriness of this substance was measured as 1250 °C. Therefore the melting point is above this value.
