以石英为原料制备白炭黑的实验研究
Experimental Study of White Carbon Black Prepared from Quartz
摘要
Abstract
In order to study the industrial preparing process of white carbon black, high-purity quartz powder which mass fraction was more than 99% was prepared by calcination-quenching-dip in sulfuric acid process and white carbon black was prepared by calcination-deposition using quartz ore, concentrated sulfuric acid, sodium carbonate and sodium hydroxide as raw materials. Through X-ray fluorescence spectrometry (XRF) and X-ray diffraction (XRD), the effects of the ratio of sodium source (Na2CO3) and quartz ratio, the sodium source (if replaced by NaOH) on the preparation of white carbon black were studied. The results showed that the amorphous white carbon black prepared by heat-treating the mixture of Na2CO3 and quartz powders, dissolving the heat-treated powder and insufflating CO2 gas into the solution. In addition, the best conditions of preparing white carbon black were obtained:n (Na2CO3): n (SiO2)=1:1, the mixture of Na2CO3 and quartz was heat-treated at 1250 ℃ for 2.5 h.关键词
