Titanium Iron Alloy Feti Lump 10~50mm

In order to obtain low-cost, low-oxygen high ferrotitanium, some researchers have used composite reducing agents to prepare high ferrotitanium. Composite reducing agents mainly include AI-Mg, AI-Ca, AI-Mg-Ca, etc. The use of composite reducing agents has the following advantages: Mg and Ca are both strong reducing agents, and their products MgO and Ca0 are both strong alkaline oxides, which are easier to combine with alumina, reducing the activity of alumina and ensuring that TiO2 is fully reduced.

According to the free enthalpy diagram, only metal reducing agents whose generated oxides are more stable than titanium oxides can produce titanium and its alloys. The metal thermal reduction method can be carried out under normal pressure or under vacuum. This method has the advantages of wide raw materials and low production cost. A large number of studies have been conducted on this method at home and abroad. It can be seen from thermodynamic calculations that metal aluminum magnesium, calcium, barium, sodium, and lithium are all ideal reducing agents for titanium dioxide. Considering the cost of reducing agents, aluminum is mainly used as a reducing agent.
