Rubidium has several uses and has a minimal impact on the environment. Some uses of rubidium include atomic clock, a dating method, fireworks display, among others.
Uses of Rubidium
- Industrially, rubidium is mostly used in making products such as photocells (converting light energy to electric energy), vapor reference cells, and lasers.
- It makes a special kind of glass that removes gases from vacuum tubes. Rubidium bonds with various gases. This property is critical in eliminating other gases that may have been produced during the manufacturing stage.
- It is used as an electrolytic additive in sodium ion batteries, used as a dietary supplement for illnesses such as depression. It is also ideal in promoting cardiovascular wellness. Although cesium would have been the preferred option, rubidium was used in ion engines.
- Rubidium-strontium dating is a method utilized by scientists in determining the age of rocks and meteorites. This is done by determining the amount of Rb 87 and strontium isotopes that is still in the material.
- Rubidium is one of the components of an atomic clock. This type of device would measure time accurately and frequently.
- Rubidium is excellent as part of a fireworks display where the explosion's color is a purplish-red.
