摘要：

Two techniques are described by which single crystals of sapphire may be grown. One is a development of the vertical-pulling technique for the production of scatter-free, low-dislocation-density material, whilst the other is an extension of a floating-zone, recrystallisation technique previously used for calcium tungstate. The origin and control of defects in crystals grown by these techniques are discussed.
