中文摘要：

采用水热法,在380℃、填充度为70%的条件下,以1.5和2.0 mol/L Na2CO3作为矿化剂,反应时间72 h,合成了硅铍钠石晶体.晶体以等轴粒状的八面体晶形为主,有少量四方柱状晶形.应用双目立体显微镜、SEM和XRD进行测试分析,发现在碱性较弱的环境中合成的晶体,除了硅铍钠石晶体外,还有一定量的六方柱状钙霞石晶体存在.提高晶体生长溶液的碱度,则硅铍钠石晶体的量明显增多.

英文摘要：

Chkalovite crystal can be synthesized by hydrothermal method with 1.5 and 2. 0 mol/L Na2h CO3 as mineralizers in the condition of filling 70%, reaction temperature 380 ℃ and reaction time 72 h. The crystal is isogranular texture, and octahedron is the major crystal form, some crystal is tetragonal prism. When the crystal is tested by microscope, scanning electron microscope and X-ray diffraction, there are some hexagonal prism cancrinite crystals when the mineralizer solution is alkalinity weak. The percentage of chkalovite crystal will increase when the mineralizer solution alkalinity increases.
