Abstract ZnAl 2 O 4 crystals were grown using few starting compositions with various ZnO:AlO 3/2 ratio using an Ir wire seed and Ir + Re crucible under ordinary pressure with Ar + 2%O 2 atmosphere by the radiofrequency heating µ-PD furnace. The ZnAl 2 O 4 spinel single crystal with 4 mm diameter could be successfully grown by the µ-PD method by optimization of starting melt composition considering with Zinc oxide evaporation. During 10 min of growth under normal pressure the formation of ZnAl 2 O 4 single phase observed even at high vapor pressure of ZnO. The transmittance spectra and X-ray locking curve were measured for evaluating of grown ZnAl 2 O 4 crystals quality.

常压下微下拉法熔融生长铝酸锌尖晶石单晶

摘要 ZnAl 2 O 4 晶体是在常压、Ar + 2%O 2 气氛下，通过射频加热μ-PD炉，使用少量具有不同ZnO:AlO 3/2 比例的起始成分，使用Ir线种子和Ir + Re坩埚，在Ar + 2%O 2 气氛下生长的。 . 通过考虑氧化锌蒸发优化起始熔体成分，可以通过 μ-PD 方法成功生长直径为 4 mm 的 ZnAl 2 O 4 尖晶石单晶。在常压下生长 10 分钟期间，即使在 ZnO 的高蒸气压下也观察到 ZnAl 2 O 4 单相的形成。测量透射光谱和X射线锁定曲线以评价生长的ZnAl 2 O 4 晶体质量。
