# What are liquidus line and solidus line?

## What are liquidus line and solidus line?

In particular, the solidus line defines the temperature below which the phases in the diagram are solid, while the liquidus line defines the temperature above which the phases are completely liquid.

What is the solidus line?

The Solidus Line is the line (or lines) on a phase diagram below which only solid is present. Technically it is “the locus of temperatures below which only solid is stable”. Associated terms: Liquidus, Phase Diagram.

### What is a solidus projection?

The solidus projection and the isothermal section show one or more three-phase regions, bounded by lines joining pairs of phases co-existing in equilibrium.

What is solidus phase diagram?

In chemistry, materials science, and physics, the solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized).

## What is liquidus projection?

Liquidus projection usually refers to a two-dimensional projection of ternary liquidus univariant lines at constant pressure. The algorithms used in Pandat for the calculation of liquidus projection with isothermal lines and invariant reaction equations in a ternary system are presented.

What are liquidus and solidus lines phase diagram?

Definition of terms: Liquidus – The line separating the field of all liquid from that of liquid plus crystals. Solidus – The line separating the field of all solid from that of liquid plus crystals. Eutectic point – the point on a phase diagram where the maximum number of allowable phases are in equilibrium.

### Is a liquidus projection A phase diagram?

Liquidus projection is one of the important types of phase diagrams. Ternary liquidus projection at constant pressure onto a compositional plane is the most commonly used type. It shows the phase rela- tionships between the liquid phase and the other phases.

What are liquidus lines?

The Liquidus Line is the line (or lines) on a phase diagram above which only liquid is present. Technically it is “the locus of temperatures above which only liquid is stable”. Associated terms: Solidus, Phase Diagram.
