Carl Auer von Welsbach used a mixture of lanthanum oxide and zirconium oxide, which he called Actinophor and patented in 1886. The original mantles gave a green-tinted light and were not very successful, and his first company, which established a factory in Atzgersdorf in 1887, failed in 1889. [53] Modern uses of lanthanum include: LaB 6 hot ...
Lanthanum(III) oxide, also known as lanthana, chemical formula La 2 O 3, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is used in some ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts, among other uses.
Lanthanum carbonate is used in medicine as a phosphate binder. [1] As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. Due to its large size (1000 mg tablet is 2.2 cm in diameter), it may be possible to choke on the tablet if it is not chewed.
In order to improve its hydrogen storage performance, metals such as lead or manganese are often used to partially replace nickel. Currently, LaNi 5 is commonly used in storage and transportation of hydrogen, hydrogen vehicle power, fuel cells, separation and purification of hydrogen, propylene hydrogenation catalysts, etc.
Lanthanum stearate is a metal-organic compound, a salt of lanthanum and stearic acid with the chemical formula La(C 18 H 35 O 2) 3. [ 1 ] [ 2 ] The compound is classified as a metallic soap , i.e. a metal derivative of a fatty acid .
Lanthanum(III) sulfide can be prepared from the effect of sulfur vapor on metallic lanthanum: 2 La + 3 S → La 2 S 3. It can also be prepared from the effect of hydrogen sulfide on lanthanum: 2 La + 3H 2 S → La 2 S 3 + 3 H 2. The effect of hydrogen sulfide on lanthanum oxide in the presence of reducing agents also produces lanthanum(III ...
Despite the importance Medicaid places on providing access to health care, many states have inconsistent policies toward paying for medications used to treat opiate addiction. The American Society of Addiction Medicine surveyed each state’s Medicaid program to determine which medications are covered and if any limitations exist.
In Fluid Catalytic Cracking (FCC), lanthanum chloride enhances catalysts to convert heavy crude into valuable fuels like gasoline and diesel. [9] Also used in the field of geology as a very dilute solution, which when combined with the proper acids can help identify small >1% Strontium content in powdered rock samples.
