In the vast universe, there is a mysterious and precious element hidden - titanium. This silver metal, with its lightness and corrosion resistance, is widely used in aerospace, medical equipment, automobile manufacturing and other fields. However, do you know where this amazing substance comes from?

1. The origin of titanium

2. Titanium content in the earth's crust
On Earth, titanium is mainly found in rocks and minerals. Among them, the most famous are rutile and ilmenite. These ores are rich in titanium, and after hundreds of millions of years of geological action, they are buried deep in the earth's crust. There are about 6 thousandths of titanium in the earth's strata, which is 61 times more than copper and ranks tenth in the earth's crust. Therefore, the reserves of titanium ore on the earth are very rich, and it is not uncommon to have more than 10 million tons of titanium ore. With the continuous exploration and development of natural resources by humans, these ores have been mined and become important raw materials for refining titanium.
