摘要
为了提高电石渣的附加值,在未使用晶型诱导剂的情况下,研究反应温度对电石渣合成纳米碳酸钙形貌的影响。结果表明:反应温度为3、8℃时,分别生成板片状和类球状方解石型碳酸钙;温度为10、80℃时,分别生成球状球霰石型碳酸钙和针状文石型碳酸钙,且球状、类球状和针状碳酸钙纳米颗粒的平均颗粒粒径分别为90、70、80 nm。
To improve the added values of carbide slags, the effect of reaction temperature on the morphology of calcium carbonate nano-particles prepared from carbide slags without crystal controlling agents was investigated. The results show that the calcite nano-particles with flake and spherical morphologies can be prepared when the reaction temperatures are 3 and 8 ℃. The vaterite and aragonite nano-particles can be prepared at the reaction temperature of 10 and 80 ℃. The average sizes of the calcium carbonate nano-particles with spherical, quasi-spherical and needle morphologies are respectively 90, 70 and 80 nm.
