Similar to potassium permanganate, the two-step decomposition of rubidium permanganate leads to the formation of rubidium manganate intermediates. It breaks down into manganese dioxide, rubidium oxide and oxygen. [4] The decomposition temperature is between 200 and 300 °C. [7] Drift-away oxygen caused an 8% mass loss in the product. [7]

Rubidium hexafluorotitanate is an inorganic compound of rubidium, fluorine, and titanium with the chemical formula Rb 2 TiF 6. [1] [2] [3] Physical properties
Rubidium-87 was the first and the most popular atom for making Bose–Einstein condensates in dilute atomic gases. Even though rubidium-85 is more abundant, rubidium-87 has a positive scattering length, which means it is mutually repulsive, at low temperatures. This prevents a collapse of all but the smallest condensates.
Rubidium hydroxide is the inorganic compound with the formula RbOH. It consists of rubidium cations and an equal number of hydroxide anions. It is a colorless solid that is commercially available as aqueous solutions from a few suppliers. Like other strong bases, rubidium hydroxide is highly caustic. Rubidium hydroxide is formed when rubidium ...
Rubidium superoxide or rubidium hyperoxide is a chemical compound with the chemical formula RbO 2. In terms of oxidation states , the negatively charged superoxide and positively charged rubidium give it a structural formula of Rb + [O 2 ] − .
