Conclusions
Studies have been carried out to refine the grain composition of the original samples and the conditions under which the chemical phase analysis on synthetic electrosmelted mullite is made.
It is established that the mullite samples should be ground to a fraction finer than 88 μ in a mortar made from tungsten carbide or from an alloy which has a better microhardness. The dissolution of the sample should be determined in 10% HF at 18–23°C for 1 h.
