Diamond's Melting Point Under Extreme Pressure Measured

Researchers at Lawrence Livermore National Laboratory (LLNL) have experimentally determined diamond's melting temperature under extreme pressures, refining previous theoretical estimates.

The study involved blasting diamond samples with a laser to create shockwaves, causing the material to melt. X-ray diffraction data was used to track this process and determine the precise melting temperature.

This experiment revealed that earlier estimates of diamond's melting point under these conditions were inaccurate by hundreds of degrees.

Understanding diamond's behavior under extreme pressure and temperature is relevant to planetary science, where diamonds can occur naturally.

The primary motivation for LLNL's research is its application to inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF).

ICF research helps investigate the behavior of materials, such as hydrogen isotopes, under conditions similar to those in nuclear weapons.

This research is not expected to impact practical power generation from nuclear fusion, which primarily relies on magnetic confinement fusion (MCF).
