Ni^(2+):BeAl_2O_4晶体的提拉法生长

Growth of Ni^(2+):BeAl_2O_4 Crystals by CZ Technique

在中频感应炉内,用〔001〕取向籽晶提拉生长出了较优质掺镍金绿宝石单晶,毛胚尺寸约为φ20×90mm。对晶体生长工艺和温场进行了研究。

A nearly perfect single crystal of Ni^(2+):BeAl_2O_4,90mm longand 20mm in diameter,has been grown by induction heating CZ techniquewith the seed of〔001〕direction.Growth technology and temperature fieldwere investigated.
