中文摘要: 对碘化法提纯金属锆进行了热力学计算，并结合试验分析了碘化反应气氛的组成。结果表明，粗锆原料在低温区被碘化，生成的碘化物在高温区分解。反应物在低温区生成ZrI4和少量的低价碘化物，ZrI4气体向高温区进行扩散，在高温区ZrI4气体受热易解离生成Zr和碘原子气体，碘原子向原料扩散，到低温区后反应生成ZrI4。经过碘化处理后，金属锆纯度有明显提高。
Abstract:Thermodynamic calculation of zirconium purification by Iodide Process was conducted. The atmosphere composition in iodide device was analyzed. The thermodynamic analysis results show that the crude zirconium is iodated in low temperature zone, the iodide zirconium decomposes into metal zirconium and iodine atom gases in high temperature zone. ZrI4 and a small amount of low valent iodide are produced from reactants in low temperature area. Upon spreading to high temperature zoon, ZrI4 gas is easily separated into metal zirconium and iodine atom gases. Iodine atoms spread to crude zirconium to generate ZrI4 in low temperature area. The purity of zirconium product is refined after iodide reaction.
