摘要:

以氧化铁红为原料, 采用硫酸一步煅烧法制备出色泽品质更高的铁红. 结果表明, 氧化铁红与60%(质量分数)的硫酸在750 ℃条件下混合煅烧效果最佳, 产物色泽有明显的改善. 通过X射线衍射(XRD)、 扫描电子显微镜(SEM)、 高分辨率透射电子显微镜(HRTEM)、 紫外-可见光谱(UV-Vis)及元素分析(EDX)等手段表征, 发现煅烧前后氧化铁红的晶型不变, 但煅烧后形貌更加规则, 粒径更加均一, 颜色更加鲜艳.

关键词: 氧化铁红, 色泽改善, 可见光, 晶体

Abstract:

Taking iron oxide red as raw material, iron oxide red with better quality was prepared by a one-step calcination method with sulfuric acid as oxidant. The results show that when iron oxide red and 60%(mass fraction) sulfuric acid were mixed and calcined at 750 ℃, the color of the product was the best. The results of XRD, SEM, HRTEM, UV-Vis and elemental analysis EDX show that the crystal form of iron oxide red was unchanged before and after calcination, but the morphology was more regular, the particle size was more uniform, and the color was more vivid after calcination.

Key words: Iron oxide red, Colour improvement, Visible light, Crystalline
