【摘要】 本文研究了十多种添加剂对α-AlPO₄晶体质量的影响。发现用 ZnCl₂作添加剂,晶体的生长速度加快,缺陷减少,适明度明显改善。X 射线能量色散谱分析证实,Zn²⁺未进入晶格,并有效地阻止其它杂质的侵入。所以 ZnCl₂是水热法生长α-AlPO₄量体较好添加剂。更多还原

【Abstract】 Influences of more than ten kinds of additives on the qualityof α-AlPO₄ crystals have been studied.Experimental results show that the use of ZnCl₂ additive results in increa-sed crystal growth rate,reduced defects,and improved transparency.X-rayenergy spectrum analysis indicates that Zn²⁺ ions have not entered into thecrystal lattice,presumably,merely being absorbed on the growth interface,and thus the intrusion of other impurities is effectively stopped.It isbelieved that ZnCl₂ is a good additive for the hydrothermal growth of α-AlPO₄crystals.更多还原
