Production method of this chemical: Firstly, take the reaction of rubidium and inadequate oxygen in the high-silica glass containers and take out the excess rubidium later. Secondly, metal rubidium reacts with excessive mercuric oxide. Keep this reaction for 12 hours at 200 °C, with the condition of tempering. Finally, steam to remove generate mercury in high vacuum, temperature 200 °C. You will get ORb₂.
