Good day, dear colleagues.

My colleague from glass community need a help.

The main goal is the Copper ion exchange searching. For this goal mixture of copper and potassium chloride according to eutectic composition was prepared. DTA shown us the transfering and melting temperature points. But some distrust melting temperature results are exist, because ion exchange can happen in molten salts.

Please, could you check these results and give us a measure evaluation.
