What is LANTHANUM?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is LANTHANUMwhich has developed particularly rapidly in recent years. Do you know about LANTHANUM?
The official answer: Lanthanum, is a metal rare earth element, the chemical symbol is La, the atomic number is 57, the atomic weight is 138.90547, the name of the element is derived from the Greek, the original meaning is “hidden”. Silvery gray luster, soft texture, density 6.162g / cm3, melting point 920 °C, boiling point 3464 °C (atmospheric pressure), chemical properties are active, exposed to the air lose metallic luster to form a blue oxide film, but it does not protect the metal, and then further oxidize to form a white oxide powder. It can interact with cold water, is soluble in acids, and can react with a variety of non-metals. Lanthanum metal is generally kept in mineral oil or noble gases. The content of lanthanum in the earth’s crust is 0.00183%, second only to cerium in rare earth elements. Lanthanum has two natural isotopes: lanthanum-139 and radioactive lanthanum-138.
What’s the application of LANTHANUM?
1, metal lanthanum shell is used for the production of nickel-metal hydride batteries, which is one of the most important applications of lanthanum.
2. It is used for the manufacture of special alloy precision optical glass, high refractive optical fiber board, suitable for cameras, cameras, microscope lenses and prisms of advanced optical instruments. It is also used to manufacture ceramic capacitors, piezoelectric ceramic admixtures, and X-ray luminescent material lanthanum oxide powder. Extracted from phosphorus cerium lanthanum ore or by burning lanthanum carbonate or lanthanum nitrate. It can also be prepared by heating and decomposing of lanthanum oxalate.
3. It can be used as a catalyst for a variety of reactions, such as catalyzing the oxidation of carbon monoxide when doping cadmium oxide, and catalyzing the hydrogenation of carbon monoxide to generate methane when doped with palladium. Lanthanum oxide, which is infiltrated with lithium oxide or zirconia (1%), can be used to make ferrite magnets. It is a very effective selective catalyst for the oxidative coupling of methane to generate ethane and ethylene. It is used to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectric bodies, as well on manufacture fiber optics and optical glasses.
4, lanthanum-138 is radioactive, half-life 1.1× 1011, has been tried to treat cancer.
