| 中文摘要 | A chromium oxide green pigment was prepared by thermal decomposition of chromium hydroxide via hydrothermal reduction of a high concentration mixture of Na2CrO4 (300 g/L) using NaHCO3 as a mineralizer. The mineralizer effects on the hydrothermal process, conversion of chromate, properties of amorphous Cr(OH)(3), and color performance of Cr2O3 were investigated. Compared with sodium carbonate and urea, sodium bicarbonate significantly reduces the Na2CrO4 concentration and, consequently, improves the conversion of Na2CrO4 during the hydrothermal process. Additionally, homogeneous particles were obtained by adding NaHCO3. The changes in the amount of trapped water, oxygen chemisorption, and negative charge on the surfaces of chromium hydroxide particles caused by adding a mineralizer were analyzed using Fourier-transform infrared spectroscopy and zeta potential analysis. The Cr2O3 pigments were characterized using X-ray diffraction, scanning electron microscopy, and an automatic differential colorimeter. A good color performance by the Cr2O3 pigment, comparable to that of a commercial pigment, was obtained. (C) 2014 Elsevier Ltd. All rights reserved. |
