摘要：
Near-net-shaped sapphire domes were successfully grown directly from the melt by novel noncapillary shaping method (NCS method). NCS combines EFG capillary feeding and bulk growth sequentially. The obtained blanks up to 80 mm diameter demonstrated a high crystalline and optical quality. Several near-net-shaped sapphire domes were grown in the course of one growth process.
