| Abstract: |
| Ti-Al-xFe-ySi alloy was synthesized from electro-titanium slag in Panzhihua by electro-aluminothermic reduction. Effect of CaO addition on slag-gold separation, alloy yield, and titanium yield was investigated. With CaO/Al of 1.1, low melting point phases such as Al2O3?CaO and 7Al2O3?12CaO are mainly produced from reduction slag, and yield of alloy and Ti is 62% and 92% respectively with oxygen content in alloy of 1.32%. Main phase of alloy is composed of TiAl3 and TiAl, Fe in slag replaces Ti in TiAl3 to form Al3Ti0.75Fe0.25, and Si is mainly combined with Ti in alloy to form Ti5Si3. Small amount of C in alloy combines with TiAl and TiSi to form new phase of Ti3SiC2 and Ti2AlC. |
