Author Response Letter to the Comments on “Thermodynamic Consideration of the Direct Removal of Oxygen from Titanium by Utilizing Metallothermic Reduction of Rare Earth Metal Halides” by Dr. Alok Awasthi

This article explores a groundbreaking method for removing oxygen from titanium, leveraging the unique properties of rare earth metals and their halides. The process involves using inexpensive reactive metals like lithium, sodium, and magnesium to reduce rare earth halides, generating valuable rare earth metals in situ. This approach not only enhances the deoxidation capabilities but also addresses the challenge of high costs associated with traditional methods. The thermodynamic analysis highlights the potential to produce titanium with oxygen concentrations below 100 mass ppm, using metals like scandium and yttrium. The article also discusses the environmental benefits, including reduced CO2 emissions and energy consumption, making it a pivotal technology for sustainable titanium recycling. Additionally, the authors respond to constructive feedback from Dr. Alok Awasthi, clarifying key points and acknowledging the importance of further experimental verification and process engineering considerations. The ongoing work and recent submissions further underscore the practical applications and future potential of this innovative deoxidation technique.
