Gallium melting plateau at standard pressure
This is the temperature at which pure gallium changes from solid to liquid under normal atmospheric pressure.
Also known as: gallium melting point
How big is it?
29.76 °C
Also 85.58 °F
Equilibrium melting temperature near 101 kPa · specified
Typical recorded range: 29.75 °C to 29.77 °C.
A little perspective
Gallium melting plateau at standard pressure is 29.75 K warmer than Water triple point.
Water triple point: The water triple point is the unique temperature and pressure at which water can exist simultaneously as solid, liquid, and vapour in equilibrium.
Measurements, assumptions & sources +
Gallium melting plateau at standard pressure
Gallium melts at about 302.9146 K (29.7646 °C) near standard pressure. Purity and pressure affect a realised plateau.
The marked equilibrium melting temperature near 101 kpa is calibrated. Unmeasured illustration details are representative.
Water triple point
The triple point of water is 273.16 K for a specified isotopic composition at its equilibrium pressure. It is distinct from ordinary freezing water at atmospheric pressure.
IAPWS — Fundamental physical constants of water
The marked triple-point temperature is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 29.76 °C
For comparison, this page uses equilibrium melting temperature near 101 kpa. The record labels this value specified, so the stated convention rather than an inferred average controls the comparison. The recorded range is 29.75 °C to 29.77 °C.
Gallium melts at about 302.9146 K (29.7646 °C) near standard pressure. Purity and pressure affect a realised plateau.
