摘要: 采用水热法生长微米级石英砂，研究在温度、温差、填充度等参数固定情况下矿化剂浓度对生长石英砂粒度的影响。结果表明，在矿化剂Na2CO3的浓度参数为1n (0.5 mol/l)生长速率较快，平均生长速率6.9 μm/d，生长后平均粒径为102.84 μm，沿(101)晶面择优生长；矿化剂浓度超过1 n范围，生长速度不再增加，且整体晶粒尺寸均匀性下降，大粒径颗粒与小粒径颗粒粒径差异变大。
Abstract: Micrometer-level quartz sand were grown by the hydrothermal method, the impact of mineralizer concentration on the grain size of the grown quartz sand, under fixed parameters such as temperature, temperature difference, and fill rate were investigated. The results show that the growth rate is faster when the concentration of the mineralizer Na2CO3 is at 1 n (0.5 mol/l), with an average growth rate of 6.9 μm/d, and the average particle size after growth is 102.84 μm, preferentially growing along the (101) crystal plane. When the concentration of the mineralizer exceeds about 1 n, the growth rate no longer increases, and the overall uniformity of crystal grain size decreases, with a larger difference in particle size between large and small grains.
