 Pure Titanium is a lustrous white metal with low density and high strength.  Titanium is as strong as steel, but it is 45% lighter.  Titanium is 60% heavier than aluminum, but it is twice as strong.  Titanium is the only element that burns in nitrogen.

 Titanium is important for alloying with aluminum, molybdenum, iron, manganese, etc.  Construction materials or chemical reactors.  Titanium Dioxide is the pigment used in (most) paint.  There is an idea of using Titanium Dioxide for purification of water, due to the reaction of the compound when it comes in contact with light.  Bombardment with deuterons can render titanium very radioactive, it will emit positions and hard gamma rays.  A typical lipstick contains 10% titanium.

 Titanium is difficult to find and create.  Titanium is found in the sun and in meteorites.  Rocks from the Apollo 17 mission to the moon contained up to 12.1% TiO 2 – Titanium Dioxide.  Titanium is present in the ash of coal, in plants, and in the human body.  Titanium could be produced commercially by reducing titanium tetrachloride with magnesium.

 The name ‘Titanium’ is based on the name of ‘Titans’ which in Greek beliefs meant first sons of the Earth.  The price of titanium metal powder (99.95%) is about $100/lb.  Titanium has low toxicity.
