稀土在烧结过程中的行为研究

A Study of the Acting of Rare Earth in the Sintering Process

采用烧结中断法及烧结矿的矿相组成、显微结构检测法,从宏观及微观两方面,研究了稀土在烧结过程中的成矿行为,稀土在烧结矿中主要形成铈钙硅石,当烧结矿中的稀土含量增加时,形成另一种新的稀土矿物。有部分稀土进入到铁酸钙中,少量稀土进入到赤铁矿、玻璃质中,微量稀土进入到磁铁矿中。

Sinting acting of rare earth in sintering process was investiqated by deviding sintering process,phase composition and microstructural analysis.Rare earth exists mainly in the form of calcium cerite in the sinter.When content of rare earth in the sinter increased,a new rare earth mainly entered in calciurn ferrite,hematite and vitreous and trace of rare earth entered in magnetite.
