Product Code : EM-La2O3-5N-Cu
Lanthanum oxide (La2O3) is an excellent evaporation material commonly used in vacuum deposition and thin film coating processes. It can be used to deposit a variety of thin-film materials, including conductive, dielectric and optical coatings. Lanthanum oxide is an ideal choice for applications requiring a high-temperature and chemically durable thin-film coating, such as in the fields of optical telecommunications, flat panel displays, aerospace, and optoelectronic devices.
When evaporating lanthanum oxide, a tungsten or carbon boat is typically required when using thermal evaporation. This is due to its high melting point of 2700⁰C and its viscosity at vaporization temperatures. The high vapor pressure of lanthanum oxide also means it is more suitable for electron beam evaporation, where it can be volatile-free for best performance.
