Conclusions
The fineness of the mineral constituent of the batch is especially important in the production of foamed insulating refractories, determining the stability of the foam mass, and the strength of the refractory, which are improved with an increase in the ehamotte's content of finely dispersed fractions, and a reduction in the maximum grain size.
