Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. 

2 HNO3 + SrCO3 → Sr(NO3)2 + H2O + CO2

As a divalent ion with an ionic radius similar to that of Ca2+ (1.13 Å and 0.99 Å respectively), Sr2+ ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. 
Strontium nitrate is thus used in electrophysiology experiments.

Strontium (atomic symbol: Sr, atomic number: 38) is a Block S, Group 2, Period 5 element with an atomic weight of 87.62 . 
Strontium Bohr ModelThe number of electrons in each of Strontium's shells is [2, 8, 18, 8, 2] and its electron configuration is [Kr] 5s2. 
The strontium atom has a radius of 215 pm and a Van der Waals radius of 249 pm. 
Strontium was discovered by William Cruickshank in 1787 and first isolated by Humphry Davy in 1808. 
In its elemental form, strontium is a soft, silvery white metallic solid that quickly turns yellow when exposed to air. 
Elemental StrontiumCathode ray tubes in televisions are made of strontium, which are becoming increasingly displaced by other display technologies pyrotechnics and fireworks employ strontium salts to achieve a bright red color.
Radioactive isotopes of strontium have been used in radioisotope thermoelectric generators (RTGs) and for certain cancer treatments. 
In nature, most strontium is found in celestite (as strontium sulfate) and strontianite (as strontium carbonate). 
Strontium was named after the Scottish town where it was discovered.

Strontium Nitrate is a white crystalline solid composed of the elements strontium, nitrogen and oxygen.  
Strontium nitrate possesses oxidising properties and produces a vibrant, red flame when used in fireworks, signal flares and pyrotechnics.

Strontium nitrate has the molecular formula of Sr(NO3)2 and the molecular weight of 211.6327 g/mol. 
Strontium nitrate is prepared by treating strontium carbonate with nitric acid. 
The solution is evaporated and crystallized:
SrCO3 +HNO3 ? Sr(NO3)2 + CO2 +H2O
Crystallization yields the tetrahydrate, Sr(NO3)2· 4H2O, which, on heating, melts at 31.3 °C in its own waters of hydration and then decomposes >100 °C to form the anhydrous nitrate. 
The anhydrate melts at 570 °C (It begins to decompose as low as 545 °C), is soluble in water (70.3 gm/100 ml at 20 °C) and is very slightly soluble in ethanol. 
These colorless crystals, or white powder, have a density of 2.986 g/cm3 and its CAS number is 10042-76-9. It is very soluble in water, as shown in Table 4.11 on the following page. 
Strontium nitrate apparently forms only the tetrahydrate when a solution is evaporated below 80°C. 
Otherwise it decomposes at higher solution temperatures to Sr(OH)2 and nitrogen oxides. 
The nitric acid concentration makes little difference in the hydrate produced, in contrast to other alkaline earths like Ca and Mg.

Strontium Nitrate is used as an oxidizer in some types of pyrotechnic compositions to give a brilliant red color. A well-known example is flares.

Actually making it is very simple.

The oxidizing properties of this salt are advantageous in such applications. 

Strontium nitrate can aid in eliminating and lessening skin irritations. 
When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation significantly better than using glycolic acid alone.

Strontium nitrate [Sr(NO3)2], because of the bright red flame it produces when burned, is used in fireworks, matches, marine signals, and so forth.

Industrial uses of strontium nitrate are rather limited and have rather limited commercial value because the corresponding calcium and barium compounds serve the same purpose yet are cheaper. 
A few, however, have found application in industry and elsewhere. 
Strontium nitrate, Sr(NO3)2, and strontium chlorate,Sr(ClO3)2, are extremely volatile and impart a brilliant crimson color to flames; they are thus used in fireworks and similar displays.
Recent clinical studies demonstrate that when strontium nitrate is applied to the facial skin, it significantly reduces skincare-induced burning, stinging and facial redness. 
These findings are very important to Rosacea sufferers, who report facial burning and flushing to topical skincare products and environmental insults such as wind, sun, heat and cold. 
This is the first compound that selectively blocks the irritationproducing nerve endings (type C nociceptors) that become activated when itching, burning and stinging occur from any cause. 
Glycolic acid removes the upper layer of old and dead skin cells, while encouraging the growth of younger, smoother and evenly pigmented looking skin. 
Strontium nitrate is a substance capable of inhibiting tingling sensations and irritations associated with peels containing glycolic acid. 
Strontium nitrate reduces irritations, inflammations, and redness caused by glycolic acid peels.

Strontium Nitrate is mainly used in the manufacture of glass substrates for display glass (LCD) and special optical glass software.

Strontium Nitrate is widely used in pyrotechnics, providing a bright red color in different pyrotechnic products such as emergency flares, tracer ammunition and fireworks.

Main applications are in the automotive and marine industries, where it is used as a pioneer in the manufacture of red flares and other emergency signaling devices, and in airbags.

Strontium nitrate is also used in the production of Strontium Chromate, which is used as a corrosion inhibitor in coating paints.

Strontium nitrate is used as a raw material for the production of Strontium Chloride for the production of special chemicals in the chemical industry.

An oxidizer commonly used as a red coloring agent often with chlorine donors and metal fuels in stars, flares, fountains, sparklers and other fireworks.

Although they are not interchangeable with Strontium Nitrate, other red coloring agents are strontium sulfate, strontium carbonate, and the salt strontium chloride.

Strontium Nitrate is used as an oxidizer in some types of pyrotechnic compositions to give a brilliant red color.
A well-known example is flares.
