A dark gray shiny metallic element. Titanium was identified by William Gregor in 1791 and separated in 1825 by Baron Berzelius. It has an abundance of 0.63% and occurs primarily in Rutile, Anatase, Sphene, Titanite, Ilmenite, perovskite, or brookite minerals. Titanium is strong but lightweight. It is used as a metal alloy with [[copper], Iron, and Steel, to add strength while decreasing mass. Titanium alloys are used in aircraft, missiles, and space capsules. The Mercury, Gemini, and Apollo capsules were mostly made of titanium. Titanium compounds are used as abrasives and pigments. Synthetically produced zinc antimony titanate was considered the best ceramic opacifier in the early 20th c.
