摘要
对熔渣的理化性质及有效硅研究结果表明 :溶渣化学成分主要以SiO2 、CaO、Al2 O3 为主 ,其中以SiO2 含量最高 ;另外含有某些微量元素及其他一些重金属元素 ;大部分熔渣呈碱性 .溶渣中可溶性硅含量在 8.9～ 1 34 .3g/kg,且以铁渣 ,铬渣含量较高 ,可以供施给缺硅或高氮的土壤 .并对可溶性硅及水溶性硅的含量与全铁 ,全铝 ,全硅 ,全钙 。
Research into Physico-chemical property of Scoria and its effective silicon contained shows that apart from some minor elements and heavy metal elements,Its chemical compositions mainly consist of SiO 2, CaO, Al 2O 3,of which the SiO 2 is relatively more contained .The soluble Si in the scoria especially the dross and Cr-contained scoria amounts from 8.9～134.3 g/kg,which can be applied to the Si-lacked soil or high-nitrogened soil.and this paper respectively analyses the relationship between soluble Si and water miscible Si and whole Fe ,Al,Si,Ca,Mg contained?
