Diffusion of Ag⁺ and K⁺ ions from AgNO₃ and KNO₃ melts into SIMAX glass was studied at 335 °C (AgNO₃) and 400-500 °C (KNO₃) using a 6-hour exposure. The concentration profile of silver was determined by the method of gradual etching of layers, and the silver concentration was measured by an ionically selective electrode. The diffusions profiles of potassium were deter­mined by the JXA-5 electron microanalyzer. The diffusion profiles of silver and potassium were used for calculating the interdiffusion coefficients, and the temperature dependence of D̅_Na+/K+ was established.
