Sodium chloride and water form a eutectoid when the mixture is 23.3% salt by mass with a eutectic point at -21.2 degrees Celsius. The system is used to make ice cream and to melt ice and snow.; The eutectic point of the mixture of ethanol and water is nearly pure ethanol.

The eutectic NaNO 3-KNO 3 mixture has the chemical composition Na 0.5 K 0.5 NO 3. Due to the lower mass of Na, this corresponds to a 45.67% NaNO 3 –54.33% KNO 3 weight percentage composition. The "solar salt" mixture has a higher content of Na, with a chemical composition of Na 0.641 K 0.359 NO 3 and a weight percentage of 60% NaNO 3 ...

Specifically, by using a novel flexible U-shaped quartz-capillary, filled with a eutectic mixture of gallium, indium and tin, commercially known as Galinstan, we proceed to measure the thermal conductivity of molten eutectic $$hbox {KNO}_3$$ – $$hbox {NaNO}_3$$ – $$hbox {NaNO}_2$$ .

eutectic, the one mixture of a set of substances able to dissolve in one another as liquids that, of all such mixtures, liquefies at the lowest temperature.If an arbitrarily chosen liquid mixture of such substances is cooled, a temperature will be reached at which one component will begin to separate in its solid form and will continue to do so as the temperature is further decreased.

Herein, the NaNO 3 –KNO 3 eutectic plays important roles in the formation of better-dispersed ZnO nanocrystallites. The method of adding precursor to NaNO 3 –KNO 3 eutectic with the required ratio is often close to an eutectic stoichiometry, which will afterwards accelerate the kinetics of synthesis of the desired products. In the process, the eutectic serves as a solvent with no direct ...

To prepare the ternary mixtures, pure NaNO 3 (CAS ), KNO 3 (CAS ), and NaNO 2 (CAS ) (Sigma Aldrich), all analytical grade, were heated in a flask up to ~ 320 °C, i.e., above the melting temperature of each component. After adequate stirring, the salts were poured out on an alumina sheet and cooled down. Afterwards, they were powdered inside a mortar.

LiNO 3-NaNO 3-KNO 3 (38:15:47 by molar ratio) was chosen since this eutectic has the highest specific heat among other ternary eutectics (1.63 kJ/kg°C) and a low melting point (below 100°C) []. A simple two-step synthesis method was used to prepare pure ternary salt eutectic samples and their mixtures with nanoparticles.

Co-amorphous drug–drug systems have been developed with the overall aim of improving the physical stability of two or more amorphous drugs. Co-amorphous systems often show good physical stability, and higher solubility and dissolution rates compared to their crystalline counterparts. The aim of this study is to determine if eutectic mixtures of two drugs can form stable co-amorphous systems.
