Strontium was discovered in 1790 in Scotland and later isolated. It is a solid metal with a silvery color that can change colors during reactions. Strontium is commonly used in fireworks due to its ability to change flame colors and is also found in nuclear bombs and gemstones. While strontium does not exist alone naturally, its salts and compounds have various commercial and industrial uses.

1. Strontium

2. History of Strontium
• Discovered in 1790 by Adair Crawford in
Strontian, Scotland.
• The element was later isolated by Sir Humphry
Davy.

3. 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

4. • Because of the different colors
formed in a reaction with
Strontium, it is often used in
fireworks.

5. Here is a video that shows how
Strontium can change the color of a
flame, making it useful in
pyrotechnics.

6. 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.

7. 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..
