Introduction
Lanthanum oxide (La2O3), also known as oxyortholanadate, is an oxide of a rare-earth element that is most commonly found in the form of crystalline powders and is used in many industries and applications. As a white powder, lanthanum oxide exhibits excellent physical, chemical, and electrical properties, making it a key component of many emerging technologies.
History
Lanthanum oxide was first discovered in 1889 by German chemist Carl Auer von Welsbach, who also discovered the element lanthanum. But it wasn’t until 1964 when lanthanum oxide was commercially used in a glassblowing process. Today, lanthanum oxide is a widely used material in many industries and scientific and research applications.
Properties
Lanthanum oxide is an insoluble compound that is highly reactive and often used as an additive to various materials. The compound is also characterized by its low thermal conductivity and relative inertness. These qualities make lanthanum oxide an ideal choice for many applications dependent on its electrical and thermal insulation. and protection from the elements.
