Physicists Identify New Clathrate in 1945 Trinity Debris, 80 Years After 21-Kiloton Blast
2 articles · Updated · Gizmodo · May 11
A previously unknown clathrate crystal has been identified in red trinitite from the July 16, 1945 Trinity test, marking the first crystallographically confirmed clathrate found among solid products of a nuclear explosion.
Temperatures above 1,500C and pressures near 1 million psi during the 21-kiloton blast fused vaporized tower metals with desert sand, creating a silicon-calcium-iron-copper lattice unlike conventionally synthesized materials.
Luca Bindi and collaborators at Princeton, Carnegie Mellon and the Slovak Academy of Sciences used single-crystal X-ray diffraction to map the crystal’s 3D cage structure, including 12-faced and 14-faced silicon cages.
The team could not link the new clathrate to an unusual Trinity quasicrystal reported in 2021, but said metallic droplets in red trinitite still contain other unexplained phases.
Researchers said the find could improve models of how complex crystals form under extreme conditions and aid work on clathrates used in batteries, solar cells, quantum devices and other advanced materials.

Discovery of a Unique Quasicrystal Clathrate from the Trinity Nuclear Test: Scientific Breakthroughs, Formation Mechanisms, and Implications for Nuclear Forensics
Overview
The Trinity nuclear test in 1945 created not only a massive explosion but also led to the formation of new and unexpected materials. When the plutonium device called 'Gadget' detonated, it produced a fireball that melted desert sand into radioactive glass and left a large crater. Among the debris, scientists recently discovered a unique quasicrystal with a complex atomic structure, formed under the extreme heat and pressure of the blast. This rare material, found in red trinitite, offers new insights into how matter transforms in violent events and has important implications for nuclear forensics and material science.
