Is lanthanum a good material?

In particular, lanthanum (La) and La-based materials have garnered attention in recent years due to their versatile properties and wide range of potential applications. This critical review provides a comprehensive overview of the advancements in the utilization of La and its compounds across various fields.

Why is lanthanum used in rechargeable batteries?

Along with supercapacitors, lanthanum is extensively used in rechargeable batteries, especially as electrode materials of Li-ion batteries like Li 1-x La x FePO 4 and Li 0.5 La 0.5 TiO 3 . The La-rich material reduces Li-ion conduction due to the small concentration of Li-ions and charge-carrying vacancies.

How is lanthanum used in medical imaging?

Medical imaging involves extensive use of radioactive lanthanum isotopes. As a positron emitter, the application of La-177 has been found in both the detection and treatment of cancer. It is injected into a vein and transported to the tumour location, where it accumulates and releases positrons.

Can lanthanum titanate be used as a ceramic electrolyte?

Jung and co-workers doped La 2 NiO 4 with Sr 2+ and Ca 2+ and demonstrated its usefulness for rechargeable Li-air and Zn-air batteries. Doping Ag in lanthanum titanate as a ceramic electrolyte in Li-ion batteries improved the conductivity, although over-doping of Ag reduced the conductivity of Li 0.5 La 0.5 TiO 3.

What is lanthanum in the periodic table?

Figure 1 shows the periodic table, including REEs . Specifically, the element lanthanum (La) is the first of the lanthanide series, with an atomic number of 57, a stable oxidation state of + 3, and a radial reaction with air to form an oxide layer .

When was lanthanum discovered?

Lanthanum's history is intertwined with the broader history of REEs. The first such heavy mineral was found in 1751 in a Swedish mine. Some 52 years later, in 1803, scientist Wilhelm Hassinger studied that mineral and isolated a new oxide of that mineral that he called cerium oxide.
