X光衍射发现,钠化提钒球团比白球（未加Na_2SO_4）有多余的衍射线存在。经水浮选富集后,判定这些多余的衍射线是NaAlSiO_4（霞石）相。通过分析证实,该相的存在量与Na、Al、Si的含量有关,它们主要分布在结晶相颗粒之间。假定浸钒后钠化球团中的SiO_2完全生成NaAlSiO_4相,对于含SiO_2为2.02%的球团,经计算霞石含量约为4.8%,则霞石中的钠约占浸钒后钠化球团中钠的残留总量的76%。稀盐酸浸泡前后纳的变化为75%。由Fe_2O_3的点阵常数测定和影响固溶体形成的主要因素分析,认为钠离子进入Fe_2O_3晶格是很困难的。
X-ray diffraction found that sodium diffusive vanadium pellets than the white ball (without Na_2SO_4) there is excess diffraction lines exist. After the enrichment by water flotation, it is determined that these extra diffraction lines are NaAlSiO 4 (nepheline) phases. It is confirmed by analysis that the amount of this phase is related to the content of Na, Al and Si, and they are mainly distributed between the crystal phase grains. Assuming that the Na 2 SiO 2 in the sodium-containing pellets is completely NaAlSiO 4 after vanadium dipping, and the content of nepheline is about 4.8% for pellets containing 2.02% SiO 2, the sodium in nepheline accounts for about 500% 76% of the total residual sodium in the pellet. Dilute hydrochloric acid before and after immersion change of 75%. According to the determination of the lattice constant of Fe 2 O 3 and the main factors influencing the formation of solid solution, it is considered that it is very difficult to enter the Fe 2 O 3 crystal lattice.
