LaAl12O19
ceramic· LaAl12O19
LaAl12O19 (lanthanum aluminate) is a ceramic compound combining rare-earth lanthanum with aluminum oxide, belonging to the family of lanthanide aluminates used in high-temperature and optical applications. It is primarily employed in phosphor host materials for lighting and display technologies, as well as in refractory and thermal barrier coating systems where its stability at elevated temperatures is valued. The material is notable for its ability to host rare-earth dopants (such as Ce³⁺ or Eu³⁺) that enable efficient luminescence, making it a competitive alternative to yttrium-based aluminates in specialized lighting and scintillation detector applications.
