Study on fabrication of metallic Titanium from secondary Titanium slag of Binh Dinh titanium minerals using magnesiothermic reduction method

Abstract

Titanium and its alloys are used in aviation, marine, medical, chemical and other fields because of their superior properties, such as low density, good corrosion resistance, high strength and biocompatibility. This paper presented a study on the possibility of producing metal titanium from secondary titanium slag by magnesiothermic reduction. The prepared products were characterized using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), and electron microscopy (SEM). The research results show that the magnesiothermic reduction method is capable of producing Ti metal directly from the secondary titanium slag with high recovery efficient. The resulting product is high-purity porous titanium, with a titanium content of up to 94,68% (without unfavourable impurities). The properties of Ti meet the requirements for the production of high-quality titanium alloys.
