Lattice constants of sodium chlorate and sodium bromate and their mixed crystals were determined over the temperature range from room temperature to 320 °C. The observed lattice constants for the various compositions show strong deviations from those expected from Vegard's rule. The lattice constants at various temperatures were fitted to polynomials of type a = a 0 + a 1 t + a 2 t 2 . The linear coefficients of expansion for the Na(ClO 3 ) x · (BrO 3 ) 1− x series varies non‐linearly with composition showing negative deviations from linearity.
