摘要:
盐酸法钛白废液富含氯化亚铁,可对其进行回收利用,从而实现盐酸法钛白废液的资源化处理。本研究通过除杂-氧化-煅烧工艺路线,以盐酸法钛白废液为原料制备氧化铁红,进而合成Fe-Cr系黑色陶瓷色料并应用于黑色陶瓷。考察了反应物摩尔比、Fe2+初始浓度、曝气速率及氧化温度对氧化铁黄制备的影响,并探究了煅烧温度对氧化铁红、Fe-Cr系黑色陶瓷色料的形成及黑色陶瓷发色的影响。结果表明:盐酸法钛白废液提纯后得到氯化亚铁净化液,在反应物摩尔比为2.4∶1、Fe2+初始浓度为0.5 mol/L、曝气速率为1.5 L/min、氧化温度为40 ℃的条件下制得氧化铁黄,经750 ℃煅烧可得到纯度为98.384%、中位粒径为3.575 μm、L*、a*、b*值为38、24.8、21.5的氧化铁红。以此为原料,在1 250 ℃下合成的Fe-Cr系黑色陶瓷色料应用于黑色陶瓷时,发色效果最优,L*=36.54、a*=1.05、b*=0.86,各项指标与标准样品高度吻合。本研究实现了盐酸法钛白废液的高值转化,提高了经济和环境效益。
