摘　　要：应用水热生长法,采用双温区高压反应釜、贵金属内衬,矿化剂使用KOH、NaOH和Na2CO3,生长出了毫米级六方结构的透明ZnO单晶。分析了ZnO晶体的结构和形貌,对水热条件下温度、温差、填充度、矿化剂种类和浓度等因素对于ZnO晶体的结晶速度和结晶形貌的影响进行了深入研究,并对结果进行了分析和讨论。Bulk single crystals of Zinc Oxide （ZnO） were grown by the hydrothermal method using a pressure-resistant autoclave and a Au inner container in it for preventing impurity incorporation from the surface. KOH,NaOH and Na2CO3 was used as mineralizer Structure and morphological characteristics of ZnO single crystals has been studied. And the influence factors on hydrothermal growth such as growth temperature, temperature difference, fill ing factor , mineralizer varieties and their consentration have been discussed.
