4 FAQs about Strontium in new energy storage

How long does strontium last?

The biological half-life of strontium in humans has variously been reported as from 14 to 600 days, 1,000 days, 18 years, 30 years and, at an upper limit, 49 years. The wide-ranging published biological half-life figures are explained by strontium's complex metabolism within the body.

What is strontium used for?

Consuming 75% of production, the primary use for strontium was in glass for colour television cathode-ray tubes, where it prevented X-ray emission. This application for strontium has been declining because CRTs are being replaced by other display methods.

Is strontium radioactive?

While natural strontium (which is mostly the isotope strontium-88) is stable, the synthetic strontium-90 is radioactive and is one of the most dangerous components of nuclear fallout, as strontium is absorbed by the body in a similar manner to calcium. Natural stable strontium is not hazardous to health at low levels.

Is strontium an alkaline earth metal?

An alkaline earth metal, it is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium.
