SUMMARY

The discussion centers on the formation of silica (SiO2) in anaerobic lunar environments, particularly under high temperatures resulting from planetesimal collisions with proto-Earth. It is established that covalent bonds can be broken at elevated temperatures, potentially allowing for oxygen incorporation. However, the stability of SiO2 as a thermodynamic product raises questions about the conditions necessary for its formation in such environments. The highest experimental temperature for silica formation in anaerobic conditions remains an open question.

PREREQUISITES
  • Understanding of covalent bond dynamics
  • Knowledge of thermodynamics related to silica (SiO2)
  • Familiarity with lunar geology and planetary formation processes
  • Basic principles of anaerobic chemical reactions
NEXT STEPS
  • Research the thermodynamic stability of silica (SiO2) under varying temperatures

Perhaps the recent silica found on the Moon highlands resulted from the extreme conditions of temperature and pressure of planetesimal collision with proto-earth. Can covalent bonds be broken at high temperatures, allowing oxygen incorporation in an anaerobic environment? What is the highest experimental temperature for silica formation in an anaerobic environment?

No idea what you are asking about. Can the bonds be broken - sure, it is all matter of how high the temperature is. But I have no idea how do you expect it to be related to silica creation. If there is a mixture containing silicon and oxygen, SiO2 is usually one of the most thermodynamically stable substances between likely products.
