High Purity Lanthanum Sputtering Target (La)

Lanthanum metal can be used to produce nickel hydrogen batteries, which is one of the most important applications of lanthanum.

Manufacturing special alloy precision optical glass, high refractive optical fiber board, cameras, cameras, microscope lenses, and advanced optical instrument prisms. We also used the manufacturing of ceramic capacitors, piezoelectric ceramic dopants, and X-ray luminescent materials such as lanthanum bromide powder.

Used as a catalyst for various reactions to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, as well as to manufacture fiber optic devices and optical glasses.

Lanthanum sputtering targets are highly valued for their ability to deliver high-purity, stable thin film deposition in advanced manufacturing. Typically produced at purity levels of 99.9%–99.99% or higher, these targets ensure low impurity incorporation and consistent sputtering behavior, resulting in uniform, high-quality coatings. This is especially critical for semiconductor and optical applications where film composition and precision directly affect device performance.

Another key advantage is their strong chemical reactivity and functional film-forming capability. Lanthanum readily reacts with oxygen or nitrogen during reactive sputtering, enabling the formation of high-performance oxide and nitride films, such as high-k dielectric layers used in advanced CMOS devices and optical coatings with high refractive index.  These functional materials are essential for improving electrical efficiency, reducing leakage current, and enhancing optical performance in modern electronics and photonics.

In addition, lanthanum sputtering targets exhibit unique electronic properties and vacuum gettering ability, making them particularly useful in specialized applications. Thin films derived from lanthanum can provide low work function for efficient electron emission and can also act as getters, absorbing residual gases to maintain high vacuum conditions.  This combination of electronic functionality and environmental stability makes lanthanum targets widely used in vacuum electronics, energy devices, and advanced thin-film systems.
