One of the YScO3 phase modification, similar to Y2O3 and Sc2O3, possesses a bixbyite-type crystal structure . In our works , YScO3 (Y:Sc ratio is about 1:1) crystals were grown in the form of fibers using the laser-heated pedestal growth (LHPG) technique. This involved heating and melting the powder preform under CO2 laser irradiation, followed by rapid cooling .
