 · Equipment. A semi-quantitative test for the presence and identification of cesium and rubidium in rocks, clays, and mineral waters has been developed by the Bureau of Mines. The test can be used in the field, as a guide for the prospector, geologist, or mining engineer engaged in location or development work. It comprises two simple spot tests ...

 · Abstract. For almost 100 years after their discovery, rubidium and cesium were considered laboratory curiosities. Recent reductions in cost have stimulated interest in these metals. This paper describes their occurrence, extractive metallurgy, and known and possible uses. Download to read the full article text.

 · Sibunit-supported Ru-catalysts promoted with cesium or rubidium compounds have been comparatively studied with XPS. The cesium promoter interacts both with support and with active component. The absence of the promoter–support interaction in the case of rubidium provides a stronger interaction between promoter and active component …

 · 1. Introduction. Lepidolite, K(Li,Al) 3 (Si,Al) 4 O 10 (F,OH) 2, is a phyllosilicate mineral showing variable compositions because of the isomorphism substitutions such as K substituted by Rb and Cs, and is considered as a major source of lithium, rubidium and cesium [].Lepidolite ore has gained attention in recent years due to the increasing …

 · AbstractApplication of 1-butyl-3-metyhlimidazaolium hexafluorophosphate ([C4mim][PF6]), in the extraction of rubidium and cesium from brine solutions using 1,4,7,10,13,16-hexaoxacyclooctadecane (18C6) as extractant was investigated. Parameters that affect the extraction including pH of aqueous phase, equilibration time, dosage of the …

 · The mode of occurrence and chemical composition of five types of micas with Rb- or Cs-dominant populations of interlayer cations, collected from the Red Cross Lake rare-element pegmatites in north-central Manitoba, are described here.

 · Rubidium anthranilate and cesium salicylate could be crystallized as the monohydrates Rb (Anth) (H 2 O) and Cs (Sal) (H 2 O). Both have layer structures containing the cations and the polar groups of the ligands in core domains sandwiched by the aromatic rings above and below. The metal atoms have coordination numbers 7 and 8, …

The separation efficiency of cesium (Cs(I)) and rubidium (Rb(I)) from a synthetic brine solution containing potassium (K(I)) was improved via a kinetics-controlled strategy. Specifically, 4-tert-butyl-2-(α-methylbenzyl) phenol (t-BAMBP) dodecane solution was partially saponified by NaOH solution first and then was directly used in extraction …

 · Expanding knowledge of low valent aluminium chemistry, rubidium and caesium aluminyls are reported to complete the group 1 (Li–Cs) set of metal aluminyls. Both compounds crystallize as a contacted dimeric pair supported by M⋯π(arene) interactions with a pronounced twist between aluminyl units. Density functi

Historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications. Rubidium was discovered in 1861 but had extremely limited industrial use until the 1920s. Small quantities of rubidium-containing minerals were mined in the United States prior to the mid-1960s, but rubidium ...

 · At low cesium and rubidium content (the glasses 15C35B and 15R35B, R = 0.43 and K = 1.43) this band peaks near 1040 cm –1 and has a shoulder near 880 – 920 cm –1. For the same boron and alkali metal (Cs, Rb) contents in the glass (glass 25C25B and 25R25B, R = 1 and K = 2) a shoulder manifests clearly near 1100 – 1200 cm –1.
