Melting of potassium peroxide
The influence of pressure on the melting point of KO2 was studied within the interval 1–750 mm.
The process of melting precedes the dissociation of KO2, which begins at the temperature at which the external pressure becomes less than the equilibrium pressure.
At a pressure of ∼ 9 atm and a temperature of 565°, KO2 (with an admixture of 6.6% KOH) melts without decomposition.
It was hypothesized that there is a eutectic of KO2 with its dissociation product.
