Prediction of radon-silica systems in the Earth's mantle
Key Points
This research aims to understand how radon interacts with silica under mantle conditions.
Conducted first-principles calculations
Analyzed stable Fd 3̄ m and P 4 1 phases
Examined conditions replicating the Earth's mantle
Radon and silica form stable Fd 3̄ m phase under mantle conditions
Silica is suggested to act as a radon reservoir
Identified stable P 4 1 phase for radon-silica interactions
Abstract
First-principles calculations show that radon and silica form stable Fd 3̄ m and P 4 1 phases under mantle conditions, indicating silica can act as a radon reservoir.
