摘要

提出了一种氧化铬绿颜料的全新制备工艺。通过研究在低温氢还原过程和烧结过程中影响氧化铬颜料性能的关键因素及其作用机理，制备出性能优异的氧化铬绿颜料。结果表明，低的氢还原温度和相应Al添加剂有利于得到高质量的氧化铬绿颜料；氧化铬的烧结机制为蒸发-凝聚；此外，副产物以NaOH形式回收。该工艺基于中国科学院过程工程研究所自主研发的铬盐清洁工艺与集成技术，实现了氧化铬绿颜料的短流程清洁生产。

Abstract

A new method to prepare chromic oxide green pigment was proposed. According to the investigation of key factors and related mechanism of the hydrogen reduction and sintering step

chromic oxide green pigment with excellent performance was prepared

and NaOH as byproduct was obtained for recycling use. The results showed that lower hydrogen reduction temperature and suitable addition of Al

were beneficial to obtaining the high quality chromic oxide green pigment. Additionally

sintering mechanism of the chromic oxide green pigment was evaporation-condensation. Based on the chromate clean process and integrated technology of chromium compounds which was developed by the Institute of Process Engineering

Chinese Academy of Sciences

the new method efficiently enables the short and clean production route from chromite ore to chromic oxide green pigment

expanding application of chromate clean production.
