Cesium Niobate is a highly water insoluble crystalline Cesium source for uses compatible with higher (basic) pH environments. Cesium Niobate is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered.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.
Cesium is a Block S, Group 1, Period 6 element. The number of electrons in each of Cesium's shells is 2, 8, 18, 18, 8, 1 and its electronic configuration is [Xe] 6s1. In its elemental form cesium's CAS number is 7440-46-2. The cesium atom has a radius of 265.5.pm and it's Van der Waals radius is 200.pm. Cesium compounds are slightly toxic. Cesium is a member of the alkali group of metals. It is one of three metals that occur as a liquid at room temperature - the others are mercury and gallium. Cesium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Cesium is used as an oxygen "getter" in vacuum and electronic tubes and as a component of photoelectric cells. Cesium compounds are considered to be slightly toxic. Atomic clocks use the microwave spectral line emitted by Cesium Isotope 133 for reference. Cesium chloride is an unproven treatment for cancer. Radioactive Cesium 137 is an artificial isotope produced that is an approved radiation source for cancer radiotherapy. Under pressure, Cesium hydride is stiffer than diamond. Laboratories use various cerium compounds for their ability to hydrogenate organic compounds. Cesium was first discovered by Fustov Kirchhoff in 1860. Caesium is named for the vibrant blue lines in its spectrum. The word Caesium originates from the Latin word 'caesisus' meaning "sky blue". See Cesium research below.
Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium's CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and it's Van der Waals radius is 200.pm. Some niobium compounds are considered very toxic. Niobium is the basis for various barium titanate compositions used as dielectric coatings in telecommunications and small advanced electronics, such as cell phones, pagers and laptop computers. Niobium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium was first discovered by Charles Hatchett in 1801. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus. See Niobium research below.
