What is the real melting range of a solid mixture with a eutectic point of 65°C and a complete melting temperature of 92°C?

The melting range of a solid mixture with a eutectic point is determined by the temperatures at which the components start to melt and the temperatures at which they completely melt. In this scenario, the eutectic point is established at 65°C, which represents the lowest melting point of the mixture where the components melt completely at that specific ratio. When the mixture is heated to the eutectic temperature, the two components are in equilibrium, allowing them to melt and solidify at this point.

The complete melting temperature of the mixture is cited as 92°C. This indicates the temperature where all solid components have fully transitioned to the liquid state without remaining any solid residuals. The real melting range of this solid mixture would then start from the eutectic point (65°C) up to the complete melting temperature (92°C). Hence, the melting range encompasses both the eutectic point and the complete melting temperature, which results in the final range being from the eutectic point of 65°C to the complete melting temperature of 92°C. Therefore, this results in a melting range of 65-92°C.
