rubidium separated material

Potassium, Rubidium, Strontium, Barium, and RareEarth

Concentrations of potassium, rubidium, strontium, barium, and rareearth elements have been determined by mass spectrometric isotope dilution for eight Apollo 11 lunar samples and for some separated phases. Potassium and rubidium are at chondritic levels, strontium at 15 times, and barium and rare earths at 30 to 100 times chondritic levels.

Rubidium 82 Article about rubidium 82 by The Free Dictionary

Rubidium was discovered in 1861 by R. Bunsen and G. Kirchhoff through a spectral analysis of salts that had separated from mineral waters. The element was named for the color of its characteristic red spectral lines (Latin rubidus, red, deep red). Metallic rubidium was first obtained in

Extraction of rubidium from respirable sintering dust

In this study, 0.3% rubidium was first found in the respirable sintering dust, which existed in the form of chloride, making this waste an excellent new rubidium extraction material. (2) 95.24% of Rb can be easily recovered by water leaching under moderate conditions.

20191011&ensp·&enspA pyrophoric substance (from Greek πυροφόρος, pyrophoros, "firebearing") is a substance that ignites spontaneously in air at or below 54 °C (129 °F) (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). Examples are iron sulfide and many reactive metals including plutonium and uranium, when powdered or thinly sliced.

Hydrogen Element information, properties and uses

Hydrogen is an essential for life, the universe and just about everything. Life, in fact, is multiply dependent on it. Without hydrogen we wouldn't have the Sun to give us heat and light. There would be no useful organic compounds to form the building blocks of life. And that most essential substance for life's existence, water, would not exist.

AllOptical Switching in Rubidium Vapor Science

2005429&ensp·&enspWe report on an alloptical switch that operates at low light levels. It consists of laser beams counterpropagating through a warm rubidium vapor that induce an offaxis optical pattern. A switching laser beam causes this pattern to rotate even when the power in the switching beam is much lower than the power in the pattern. The observed switching energy density is very low, suggesting that
