Rapid determination of the concentration of alumina and silica in aluminosilicate refractories using neutron-2 equipment

Refractories Aims and scope

Conclusions

The activation analysis of aluminosilicate materials for their Al2O3 and SiO2 concentrations and a selective analysis for the concentration of Al2O3 can be used with confidence for production control in the refractory industry. Ampoules of neutron sources with an activity of ∼1·107–3·107 neutrons/sec were used. These sources require the minimum amount of safety precautions to ensure biological protection.

The rapidity of the activation analysis and the fact that the samples are more representative than those in the quantitative chemical methods makes it possible to recommend this method primarily for monitoring the quality of the raw material in the mines.
