采用浸没籽晶法以CaO-Li2O-B2O3为助熔剂生长出La2CaB10O19单晶。籽晶的方向对晶体质量有较大的影响。晶体结构导致生长出的晶体均呈现板状外形,并且容易沿(001)面解理;捆绑晶体的铂丝嵌入晶体加剧了晶体的解理。然而解理和铂丝嵌入对不同方向籽晶生长出晶体的质量影响各不相同,对于晶体生长过程溶质输运的影响也不相同,实验发现,[101]方向为本实验条件下最佳的晶体生长方向。
La2CaB10O19 single crystals were grown from CaO-Li2O-B2O3 flux by seed-submerged technique. The crystal exhibit plate-like growth habit and it is likely to cleave along (001) faces clue to the structure of crystal. The, direction of seed crystals has great influence on crystal growth. It is found that the [ 101 ] direction benefit to crystal growth than other directions.
