Iron-Carbon Phase Diagram Explained [with Graphs] - …

For the iron-carbon alloy diagram, the eutectic point is where the lines A1, A3 and ACM meet. The formation of these points is coincidental. At these points, eutectic reactions take place where a liquid phase freezes into a mixture of two solid phases.

Melting Point, Freezing Point, Boiling Point

The melting point of solid oxygen, for example, is -218.4 o C. Liquids have a characteristic temperature at which they turn into solids, known as their freezing point . In theory, the melting point of a solid should be the same as the freezing point of the liquid.

Which Material Has the Highest Melting Point? (with …

17/7/2020· Carbon, found in coal deposits, is the chemical with the highest melting point. When very high melting points are desired in a piece of hardware, sometimes ceramics are used. One example is during Project Pluto in the 1950s, when American scientists attempted to create a nuclear-powered ballistic missile with an unshielded, gigawatt-level reactor.

Carbon nanotubes make water freeze solid at boiling …

But researchers at MIT have found that, when contained inside the tiny cavities of carbon nanotubes, water can actually freeze solid at temperatures well above its usual boiling point.
