The reason is that with the increases of preplacing mass of Cr powder,the eutectic matrix of α (Fe,Cr) rich in Fe+Cr 7C 3 in alloying layer is replaced by the eutectic of α (Fe,Cr) rich in Fe+Cr 23 C 6,then replaced by α (Fe,Cr) ferrite rich in Cr.
Under slow cooling condition, the melt of the Al2O3-ZrO2 system with 75% in mass Al2O3 forms normal microstructure consisting of well developed granular primary corundum and Al2O3-ZrO2 eutectic with a slight fluctuation in the eutectic composition.
Aturbidity method has been developed to determine the solubility and meta-stable zones of ino-sioe-water and inosine-othanol-water (ethanol : water=2: 98wt%) systems. Utilizing the ther-modynamic relations of simple eutectic systems, combined with Wilson eqn. , the solid-liquid equilibrium data were correlated and predicted for inosine-water system.
The mixture of pseudo—binary system CH_3COONa·3H_2O—CH_3CONH_2 was subjected to differential scanning calorimetry in this paper. Eutectic mixture melts congruently at 28℃, the heat of fusion of the eutectic mixture of this pseudo—binary system is found to be 231J/g.
The mixture of pseudo—binary system CH_3COONa·3H_2O—C_H_O_ was investigated to differential scanningcalorimetry in this paper. Eutectic mixture melts congruently at 50℃,the heat of fusion of the eutectic mixture of thispseudo-binary system is found to be 209.3J/g.
Adopting the method of ionothermal synthesis, this paper synthetizes the (NH4)ZnPO4-HEX molecular sieve in the deep eutectic mixture system of choline chloride/urea, reviews systemically the influences of reactant composition and the crystallization time on the structural performance of (NH4)ZnPO4-HEX molecular sieve, characterizes the structure and performance of the typical sample through by using the analysis methods of XRD, SEM and FT-IR.
