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 ...
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
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.
The lanthanum contained within Phoslock reacts with phosphate to form an inert mineral known as rhabdophane (). Phoslock is used in lake restoration projects to remove excess phosphorus from aquatic systems, thereby improving water quality and inducing biological recovery in impaired freshwater systems.

The lanthanum ion is used to affect the levels of let-7a and microRNAs miR-34a in a cell throughout the cell cycle. When the lanthanum ion was introduced to the cell in vivo or in vitro, it inhibited the rapid growth and induced apoptosis of the cancer cells (specifically cervical cancer cells).
"Often those who are drinking almond milk daily are avoiding or drastically limiting dairy in their diet," says Kacie Barnes, M.C.N., RDN, a registered dietitian and owner of Mama Knows Nutrition ...
