采用氧化锌粉与cuso4溶液在室温下混合的简单方法合成了Ktenasite。合成ktenasite的x射线衍射图与矿物ktenasite的x射线衍射图非常相似。晶格参数为a=0.559, b=0.616, c=2.374nm, β=95.63°，与矿物克氏体的晶格参数较为一致。合成的ktenasite由长度在2 ~ 4μm之间的薄矩形颗粒组成。透射电镜观察表明，在a轴方向上形成了超晶格结构，在b轴方向上有明显的晶体生长。十二烷基硫酸钠（NaDS）与ktenasite的插层反应表明，随着基间距从1.17 nm扩大到2.70nm，插层发生。反应通过SO42−/DS−阴离子交换机制进行，中间层[Zn(H2O)6] so4盐溶解。
Ktenasite was synthesized by the simple method of mixing ZnO powder with CuSO4solution at room temperature. The X-ray diffraction pattern of synthesized ktenasite was very similar to that of mineral ktenasite. The lattice parameters were determined as a=0.559, b=0.616, c=2.374nm and β=95.63°, which agreed comparatively well with those for mineral ktenasite. The synthesized ktenasite consisted of thin rectangular particles ranging in size from 2 to 4μm in length. TEM observation suggested the formation of a super lattice structure in the a-axis direction and significant crystal growth in the b-axis direction. The intercalation reaction of sodium dodecyl sulfate (NaDS) with ktenasite showed that the intercalation took place accompanied by the expansion of basal spacing from 1.17 to 2.70nm. The reaction progressed by the SO42−/DS−anion exchange mechanism with the dissolution of interlayer [Zn(H2O)6]SO4salt.
