The rubidium content in minerals is often calculated and quoted in terms of Rb 2 O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate. A major source of rubidium is lepidolite, KLi 2 Al(Al,Si) 3 O 10 (F,OH) 2, wherein Rb sometimes replaces K. Rb 2 O is a yellow colored solid.

Each oxygen atom in its peroxide ion may have a full octet of 4 pairs of electrons. [6] Superoxides are a class of compounds that are very similar to peroxides, but with just one unpaired electron for each pair of oxygen atoms (O − 2). [6] These compounds form by oxidation of alkali metals with larger ionic radii (K, Rb, Cs).
It reacts with carbon dioxide to form lithium carbonate and oxygen. Sodium peroxide (Na 2 O 2) is a pale yellow solid that melts at 460 °C and decomposes at 657 °C. Potassium peroxide (K 2 O 2) is a yellow solid that melts at 490 °C. Rubidium peroxide (Rb 2 O 2) is produced when rubidium stands in air.

When the Bayer liquor is cooled, Al(OH) 3 precipitates, leaving the silicates in solution. NaAl(OH) 4 → NaOH + Al(OH) 3. The solid Al(OH) 3 Gibbsite is then calcined (heated to over 1100 °C) to give aluminium oxide: [7] 2 Al(OH) 3 → Al 2 O 3 + 3 H 2 O. The product aluminium oxide tends to be multi-phase, i.e., consisting of several phases ...
Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O).. Aluminium(I) oxide (Al 2 O); Aluminium(II) oxide (AlO) (aluminium monoxide)
Rubidium sesquioxide is a chemical compound with the formula Rb 2 O 3 or more accurately Rb 4 O 6. In terms of oxidation states , Rubidium in this compound has a nominal charge of +1, and the oxygen is a mixed peroxide ( O 2− 2 ) and superoxide ( O − 2 ) for a structural formula of (Rb + ) 4 (O − 2 ) 2 (O 2− 2 ) .
