摘要
用目视变温法和DTA法测定三元体系NaOAc-HCOONa-NaNO_3的相图,实验表明:该体系是一低共熔体系,低共熔点为176℃,组成为NaNO_3 47%;HCOONa 41%(重量百分数)
In this paper, the phase diagram of ternary system NaOAc-HCOONa NaNO_3 was studied by visual-polythermal and DTA methods. This system is eutectic type, the eutectic occurs at 176℃, 47%NaNO_3, 41%HCOONa.
