At present, the concept of high entropy oxides in complex systems consisting of 4, 5 or even more components (cations) is well known . At the same time, stabilization of the non-equilibrium rock salt phase of zinc oxide at ambient pressure can be achieved in simpler binary or ternary oxide systems in a wide range of compositions, making them potentially interesting for practical applications. Moreover, in this case the stabilization is of a kinetic nature, i.e. the reverse rs-to-w phase transformation is kinetically hindered due to a variety of reasons, including in particular the chemical pressure imposed by the multicharged cation in solid solutions of the (1-x)Li n-2 Me n+ O n-1 -xZnO type .
