川威高钛矿渣性能分析

Analy sis of Chuanwei High Titanium Slags

通过XRF光谱半定量分析、单一元素定量分析和XRD鉴定了川威高钛矿渣的化学组成和矿物成分;用SEM观察了其水冲渣和膨化渣的孔隙形貌;测试了水冲渣、膨化渣的孔隙率和水化活性。结果显示:川威高钛矿渣化学组成(28.36%CaO-26.04%SiO2-16.68%TiO2-13.80%Al2O3-7.54%MgO)均匀,钛以钙钛矿CaTiO3形式单独存在,其水冲渣和膨化渣都已充分水化,孔隙率均大于40%。可考虑提钛或以微晶玻璃形式将钛进行资源化利用,水冲渣和膨化渣的多孔特性也可用来烧制轻质保温砖和透水砖。

The chemical composition and mineral component of chuanwei high titanium slag were identified by XRF spectrum semi-quantitative analysis, single element quantitative analysis and XRD. The pore morphology of water slag and expanded slag was observed by SEM. The porosity and hydration activity of water slag and expanded slag were tested. The results showed that the chemical composition of Chuanwei high titanium slags (28.36%CaO-26.04%SiO2 -16.68%TiO2 -13.80%Al2O3 -7.54%MgO) was homogeneous, and titanium exists in the form of CaTiO3 , water slag and expanded slag have beenfully hydrated and their porosity is all greater than 40%.Based on the results, Titanium extraction or glass ceramics production can be considered for the utilization of titanium from the slag, the porous characteristics of water slag and expanded slag can also be used to fire lightweight insulation bricks and permeable bricks.
