Solidus (chemistry)

The solidus temperature indicates the temperature of an alloy, a ceramic, a rock or mineral, at and below which the substance is entirely in the solid phase.

Besides the substances mentioned have yet to the liquidus temperature. This is the temperature that the substances fully present at and above the liquid phase.

Between solidus and liquidus, the substance is mushy, there are solid and liquid phase to each other.

The temperature range between solidus and liquidus temperature is called the melting interval.

In eutectic alloys liquidus and solidus fall together, eg ISO BSn63Pb 178 (L- Sn63PbAg ) at 178 ° C. Here the transition occurs abruptly from solid to liquid and is called the eutectic point.
