History of Strontium• Discovered in 1790 by Adair Crawford in Strontian, Scotland.• The element was later isolated by Sir Humphry Davy.
Properties• Strontium is a solid at room temperature.• When it is freshly cut it is a silvery colored, however, when it reacts it can turn many different colors.• Melting point: 777 degrees Celsius• Boiling point: 1382 degrees Celsius.• Density of the solid is 2.630 kg/mL
• Because of the different colors formed in a reaction with Strontium, it is often used in fireworks.
Here is a video that shows how Strontium can change the color of a flame, making it useful in pyrotechnics.• http://www.youtube.com/watch?v=vltFchuGi 0Y
Uses• Strontium does not exist by itself, but it can be found in Strontium salts and other compounds.• Strontium salts (strontium sulphate) is used in pyrotechnics.• Strontium titanate has an extremely high refractive index so it is known to be used as a gemstone.• Radioactive Strontium ( Strontium 90) granules are found in nuclear bombs.
Availability• Even though Strontium does not exist by itself, things like Strontium Chloride can be bought in small amounts from many pyrotechnic suppliers.• This usually costs about $100 for 100 grams..
