Yttrium Aluminate Single Crystal (YAlO3, Perovskite – YAP)

Yttrium Aluminate-Perovskite (YAP) crystals is an important crystal substrate material with excellent optical performance, physical and chemical properties.  YAP crystal has a similar structure to YAG crystals.

Rare-earth and transition-metal ions doped with YAP are widely used for laser applications, scintillators, holographic record and optical data storage, dosimeters for ionizing irradiation and substrates for HTSC Film growth.
