摘要

Next to aluminum, iron and magnesium, titanium (Ti) ranks the forth most abundant structural metal in the Earth’s crust, the content of which is about 0.6%. In 1791, the British mineralogist–William Gregor, was the first to discover titanium. Countries around the world have continued to study and improve titanium extraction methods for more than a century since then.
