宽肩和快速横向生长的特点LaLuO3结晶到铱棒在直拉的配置。在仔细的温度控制下，颈缩和进一步的低速提拉提供了单晶生长，但是生长中的晶体与熔体的自发分离是生产大晶锭的强烈限制因素。Ce和Pr掺杂的单晶体的最高可达0.5立方厘米，并用于测量的X射线数据，密度，熔点和光学性能，并在退火研究。
Wide shoulder and fast lateral growth are characteristics of LaLuO3during crystallization onto an iridium rod in Czochralski's configuration. Under careful temperature control, necking in and further low-speed pulling provided for single-crystal growth, but spontaneous separation of the growing crystal from the melt is a strongly limiting factor for production of large boules. Ce- and Pr-doped single crystals of up to 0.5 cm3were obtained and used in measurements of the X-ray data, density, melting point and optical properties and in annealing studies.
