【摘要】 采用沉淀转化法制备 CuO 的前驱体 Cu（OH）₂, 对纳米 CuO 微晶的不同热分解条件下的样品进行了 X 射线衍射（XRD）实验研究．结合所获得的晶粒度和 XRD 微结构参数,发现纳米晶 CuO 的晶粒组元中存在着晶格畸变；随着温度的升高,纳米 CuO 晶粒长大且其微结构呈现出明显的变化,其晶格畸变与晶粒度有着比较密切的关系。更多还原

【Abstract】 Cu（OH）₂,the former body for the preparation of CuO,is obtained by the precipitate conversion method and thermally decomposed under different temperatures conditions.The resulted in is analyzed by XRD.Combining the particle size and XRD parameters,it is found that there is the distortion of crystal lattice in the CuO crystal particles, which is more serious at lower temperature than the higher;its relation is summarized in the results table.更多还原
