Strontium: Element Properties And Uses

Description

Strontium is an alkaline earth metal that demonstrates measurable reactivity and quantifiable physical properties. It is used in fireworks, magnets and various industrial products.

Introduction to the Element

Strontium is a soft, silvery metal that belongs to the alkaline earth metals in the periodic table. With an atomic number of 38, it occupies a significant position in group 2 alongside elements such as Calcium and Barium.

Researchers have investigated Strontium for its pronounced metallic lustre and its relatively low density when compared with heavier metals. Its physical appearance and chemical behaviour have attracted measurable academic and industrial interest. The occurrence of Strontium in the Earth’s crust is essential for geochemical and mineralogical studies, as it provides data regarding the formation of specific rock types and the distribution of alkaline earth metals.

Chemical Properties Description

Strontium exhibits several chemical properties that characterise alkaline earth metals. In its pure form, Strontium is highly reactive; however, it is typically encountered as part of stable compounds. When exposed to air, a thin oxide layer forms on its surface, thereby affording limited protection against further oxidation. In the presence of water, Strontium reacts to form strontium hydroxide, although this reaction is less vigorous than that of some heavier counterparts.

Common Applications

Strontium plays an important role in diverse industrial and commercial applications.

One established application is in the formulation of fireworks. The red colours produced by Strontium compounds, particularly strontium nitrate, are employed in pyrotechnic displays.

Apart from pyrotechnics, Strontium is used in the manufacture of ferrite magnets. Engineers use Strontium in magnetic materials to develop components for motors, sensors and audio devices.

Strontium compounds are also utilised in the glass and ceramic industries. As an additive in glass recipes, Strontium improves the optical properties and durability of the final product.

In ceramics, Strontium contributes to improved thermal stability and mechanical strength, which is critical for components operating in high-temperature environments.

Medical applications of Strontium, primarily in the form of strontium ranelate, have been investigated for their potential in treating osteoporosis. Given potential side effects, careful dosage and monitoring are required in this field.

Preparation Methods

The processing of Strontium for industrial use involves several established procedures that begin with the extraction of naturally occurring minerals. The primary sources of Strontium are celestine (strontium sulphate) and strontianite (strontium carbonate), both obtained from sedimentary deposits. Following extraction, these ores are subjected to a series of chemical treatments to separate Strontium from other elements.
