Crystal growth of La2Zr2O7 by micro-pulling-down method using Mo and W crucibles

研究成果: Article査読

抄録

La2Zr2O7 crystals with a melting point of 2283 °C are grown via the micro-pulling-down (μ-PD) method using Mo and W crucibles to expand the possibility of material research of functional single crystals with high melting points by the μ-PD method. La2Zr2O7 crystals grown using Mo and W crucibles under an Ar + 3% H2 atmosphere are composed of a La2Zr2O7 main phase, which includes Mo and W. However, a La2Zr2O7 crystal without W can be grown under an Ar atmosphere using the μ-PD method using a W crucible and deoxygenated ZrO2 insulators. After post-annealing in air at 1000 °C, the La2Zr2O7 crystal without W becomes colorless and transparent, indicating a transmittance exceeding 70% in wavelengths ranging from 450 to 800 nm.
