STRONTIUM

What Is Strontium And Where Do I Use It?

Strontium (element symbol Sr – number 38 on the periodic table) is a soft silver-white yellowish metal that is highly chemically reactive.
Strontium occurs naturally and is the 15th most abundant metal on earth.
The metal is primarily mined from the minerals celestine and strontianite.
Strontium aluminate is often used in ‘glow-in-the-dark’ paints, as it absorbs light during the day and releases it slowly for hours afterwards.
Natural strontium is stable but the synthetic strontium-90 is radioactive and is one of the most dangerous components of nuclear fallout. Natural strontium is not hazardous to health.
Strontium-90 is one of the best high-energy-beta-emitters known and can be used to generate electricity for space vehicles or remote water stations.
The metal can also be used to remove static charges from machinery handling paper of plastic.

According to data from 2019, strontium is estimated to cost approximately $6.60 per kg.

Strontium burns in air. It forms a dark oxide layer when exposed to air.
In its reactivity with water, strontium produces strontium hydroxide and hydrogen gas.
