Rubidium carbonate Uses
Rubidium carbonate shines in the production of specialty glass, particularly lithium silicate glass ceramics for dental use. According to patent data (Lithium silicate glass ceramic and glass with rubidium oxide content), Rb₂O content in these glasses ranges from 3.0 to 9.0 wt.%. Here’s a closer look:
- Example 1: At 7.7 wt.% Rb₂O, you’d use about 9.51 grams of Rb₂CO₃ per 100 grams of glass.
- Example 2: For 3.7 to 7.4 wt.% Rb₂O, the range is roughly 4.5 to 9.1 grams per 100 grams of glass.
How do we figure this out? Rb₂O has a molecular weight of about 186.94 g/mol, while Rb₂CO₃ is around 230.94 g/mol. So, 1 gram of Rb₂O needs about 1.235 grams of Rb₂CO₃. For 7.7 grams of Rb₂O, that’s approximately 9.51 grams of rubidium carbonate—pretty straightforward!
Rubidium carbonate is a handy promoter in catalysts, especially for synthesizing higher alcohols. Studies show that in rubidium-promoted iron catalysts, the Rb/Fe atomic ratio ranges from 1.44/100 to 5/100 (Fischer–Tropsch Synthesis: Characterization Rb Promoted Iron Catalyst). Let’s break it down:
- With Rb at 85.47 g/mol and Fe at 55.85 g/mol, an Rb/Fe ratio of 1.44/100 gives about 2.16 wt.% rubidium, or roughly 2.92 grams of Rb₂CO₃ per 100 grams of catalyst (since rubidium is 74% of Rb₂CO₃’s weight).
- At 5/100, it’s about 7.1 wt.% rubidium, or around 9.6 grams of Rb₂CO₃ per 100 grams.
Other research, like “Influence of Cobalt on Rubidium-Promoted Alumina-Supported Molybdenum Carbide Catalysts for Higher Alcohol Synthesis from Syngas” (link), mentions similar uses but doesn’t specify amounts, so we estimate a similar range.
