摘要：
The NaNO3-Na2CO3-Na2WO4 ternary system and its boundary binary systems NaNO3-Na2CO3, NaNO3-Na2WO4, and Na2CO3-Na2WO4 are studied by methods of a combined thermal analysis. The occurrence of simple eutetics in the binary systems in confirmed, and their liquidus curves are improved. The liquidus surface of the NaNO3-Na2CO3-Na2WO4 system is established based on the phase diagrams of the boundary systems and the series of radial sections. The surface is comprised of two large (Na2CO3 and Na2WO4) and one small (NaNO3) crystallization fields. The ternary eutectic temperature is 265 degrees C; the eutectic composition is 6 wt % Na2CO3, 6 wt % Na2WO4, and 88 wt % NaNO3.
