Titanium, when pure, is a lustrous, white metal. It has a low density, good strength, is easily fabricated, and has excellent corrosion resistance. The metal burns in air and is the only element that burns in nitrogen. It is marvellous in fireworks. Titanium is resistant to dilute sulphuric and hydrochloric acid, most organic acids, damp chlorine gas, and chloride solutions.
Titanium metal is considered to be physiologically inert.
Both values are quoted on the Pauling scale. The following CrystalMaker image represents the solid state structure. For most elements, the most stable allotrope is illustrated. This section gives some data for naturally occurring isotopes. Copyright 1997 Mark Winter Department of Chemistry at the University of Sheffield , Sheffield S3 7HF, England.
