Sulfate IonRubidium Sulfate Solutions are moderate to highly concentrated liquid solutions of Rubidium Sulfate. They are an excellent source of Rubidium Sulfate for applications requiring solubilized Compound Solutions Packaging, Bulk Quantity materials. American Elements can prepare dissolved homogenous solutions at customer specified concentrations or to the maximum stoichiometric concentration. Packaging is available in 55 gallon drums, smaller units and larger liquid totes. American Elements maintains solution production facilities in the United States, Northern Europe (Liverpool, UK), Southern Europe (Milan, Italy), Australia and China to allow for lower freight costs and quicker delivery to our customers. American Elements metal and rare earth compound solutions have numerous applications, but are commonly used in petrochemical cracking and automotive catalysts, water treatment, plating, textiles, research and in optic, laser, crystal and glass applications. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Rubidium Sulfate Powder.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar cells and fuel cells. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Related Products & Element Information

See more Rubidium products. Rubidium (atomic symbol: Rb, atomic number: 37) is a Block S, Group 1, Period 5 element with an atomic weight of 5.4678. The number of electrons in each of Rubidium's shells is [2, 8, 18, 8, 1] and its electron configuration is [Kr] 5s1. The rubidium atom has a radius of 248 pm and a Van der Waals radius of 303 pm. Rubidium Bohr ModelRubidium is highly reactive, with properties similar to other Group 1 akali metals, e.g., rapid oxidation in air. In its elemental form, rubidium has a gray white appearance. Rubidium is found in the minerals lepidolite, leucite, pollucite, carnallite, and zinnwaldite as well as some potassium minerals. Rubidium was discovered by Robert Bunsen and Gustav Kirchhoff in 1861 and was first isolated by George de Hevesy. The name Rubidium, originates from the Latin word rubidus, meaning "dark or deepest red."

See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
