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
