RUBIDIUM Metal 99.95%/99.995%
Rubidium compounds are sometimes used in fireworks to give them a purple color. Rubidium has also been considered for use in a thermoelectric generator using the magneto hydrodynamic principle, whereby hot rubidium ions are passed through a magnetic field.
These conduct electricity and act like an armature of a generator, thereby generating an electric current.
Rubidium, particularly vaporized 87Rb, is one of the most commonly used atomic species employed for laser cooling and Bose–Einstein condensation. Its desirable features for this application include the ready availability of inexpensive diode laser light at the relevant wavelength and the moderate temperatures required to obtain substantial vapor pressures.
For cold-atom applications requiring tunable interactions, 85Rb is preferred for its rich Feshbach spectrum. The resonant element in atomic clocks utilizes the hyperfine structure of rubidium's energy levels, and rubidium is useful for high-precision timing. It is used as the main component of secondary frequency references (rubidium oscillators) in cell site transmitters and other electronic transmitting, networking, and test equipment.
These rubidium standards are often used with GNSS to produce a "primary frequency standard" that has greater accuracy and is less expensive than cesium standards. Such rubidium standards are often mass-produced for the telecommunications industry.
Other potential or current uses of rubidium include a working fluid in vapor turbines, as a getter in vacuum tubes, and as a photocell component. Rubidium is also used as an ingredient in special types of glass, in the production of superoxide by burning in oxygen, in the study of potassium ion channels in biology, and as the vapor in atomic magnetometers. In particular, 87Rb issued with other alkali metals in the development of spin-exchange relaxation-free magnetometers.
SODIUM Metal 99.50% - 99.99%
Sodium is a soft, silvery color metal which, like other members of the alkali group of metals, is extremely reactive. As for the other members of the group, it can be prepared by electrolysis of the fused halide or hydroxide. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust. primarily as the carbonate, chloride or nitrate. Molten sodium is used as a heat exchanger in certain types of nuclear reactors and as a reagent in the chemicals industry. Some of the sodium salts e.g. NaCl and NaCO₃) are more important than the metal itself due to the variety of applications for which they can be used.

Sodium forms alloys with many metals, such as potassium, calcium, lead, and the group 11 and 12 elements. Sodium and potassium form KNa2 and NaK. NaK is 40–90% potassium and it is liquid at ambient temperature. It is an excellent thermal and electrical conductor. Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl2 and ternary mixture NaCl-CaCl2-BaCl2. Calcium is only partially miscible with sodium, and the 1-2% of it dissolved in the sodium obtained from said mixtures can be precipitated by cooling to 120 °C and filtering.
In a liquid state, sodium is completely miscible with lead. There are several methods to make sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. NaPb3, NaPb, Na9Pb4, Na5Pb2, and Na15Pb4 are some of the known sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. NaPb3, NaPb, Na9Pb4, Na5Pb2, and Na15Pb4 are some of the known sodium-lead alloys. Sodium also forms alloys with gold (NaAu2) and silver (NaAg2). Group 12 metals (zinc, cadmium and mercury) are known to make alloys with sodium. NaZn13 and NaCd2 are alloys of zinc and cadmium. Sodium and mercury form NaHg, NaHg4, NaHg2, Na3Hg2, and Na3Hg.
Metallic sodium is used mainly for the production of sodium borohydride, sodium azide, indigo, and triphenylphosphine. A once-common use was the making of tetraethyllead and titanium metal; because of the move away from TEL and new titanium production methods, the production of sodium declined after 1970.Sodium is also used as an alloying metal, an anti-scaling agent, [64] and as a reducing agent for metals when other materials are ineffective. Note the free element is not used as a scaling agent, ions in the water are exchanged for sodium ions. Sodium plasma ("vapor") lamps are often used for street lighting in cities, shedding light that ranges from yellow-orange to peach as the pressure increases. By itself or with potassium, sodium is a desiccant; it gives an intense blue coloration with benzophenone when the desiccate is dry
Metallic sodium is generally less reactive than potassium and more reactive than lithium. Sodium metal is highly reducing, with the standard reduction potential for the Na+/Na couple being −2.71 volts, though potassium and lithium have even more negative potentials. Liquid sodium is a popular coolant for the fast breeder reactor.
CESIUM Metal 99.95%/99.99%
Petroleum exploration: The largest present-day use of nonradioactive caesium is in caesium format drilling fluids for the extractive oil industry.
Atomic clocks: A room with a black box in the foreground and six control cabinets with space for five to six racks each.
Electric power and electronics: Caesium vapor thermionic generators are low-power devices that convert heat energy to electrical energy.
Caesium is also important for its photoemissive properties: converting light to electron flow. It is used in photoelectric cells because caesium-based cathodes, such as the intermetallic compound K
CsSb, have a low threshold voltage for emission of electrons. The range of photo emissive devices using caesium include optical character recognition devices, photomultiplier tubes, and video camera tubes.
Caesium iodide (CsI), bromide (CsBr) and fluoride (CsF) crystals: are employed for scintillators in scintillation counters widely used in mineral exploration and particle physics research to detect gamma and X-ray radiation. Being a heavy element, caesium provides good stopping power with better detection. Caesium compounds may provide a faster response (CsF) and be less hygroscopic (CsI).
Caesium vapour is used in many common magnetometers.
The element is used as an internal standard in spectrophotometry. Like other alkali metals, caesium has a great affinity for oxygen and is used as a "getter" in vacuum tubes. Other uses of the metal include high-energy lasers, vapor glow lamps, and vapor rectifiers.
Centrifugation fluids
The high density of the caesium ion makes solutions of caesium chloride, caesium sulfate, and caesium trifluoroacetate. useful in molecular biology for density gradient ultracentrifugation. This technology is used primarily in the isolation of viral particles, subcellular organelles and fractions, and nucleic acids from biological samples.
Chemical and medical use : Caesium fluoride enjoys a niche use in organic chemistry as a base and as an anhydrous source of fluoride ion
Nuclear and isotope applications: Caesium-137 is a radioisotope commonly used as a gamma-emitter in industrial applications. Its advantages include a half-life of roughly 30 years, its availability from the nuclear fuel cycle, and having 137Ba as a stable end product.
