Strontium nitrate, Sr(N03)2 is made by dissolving strontium carbonate in nitric acid. It is mixed with carbon and sulfur to make red fire for use in fireworks, signal shells, and railroad flares. Strontium chlorate, Sr(ClD3)2, is used for the same purpose. 

When our family gets to the park, they find themselves a place on the lawn, which was fertilized with a mixture of ionic compounds, including iron(II) sulfate. They eat their dinner and play in the park until it s time for the fireworks. The safety matches used to light the rockets contain barium chromate, and ionic compounds in the fireworks provide the colors red from strontium chlorate, white from magnesium nitrate, and blue from copper(II) chloride. 

BARIUM SULFIDE (21109-95-5) BaS Flammable solid. Oxidizes in dry air. Contact with acid, acid fumes, moisture, steam, or moist air causes decomposition with the formation of toxic and flammable hydrogen sulfide gas. Evolved gas can form explosive mixtures with air and may cause spontaneous ignition or explosion. Violent reaction with strong oxidizers, calcium chlorate calcium nitrate chlorine dioxide phosphorus(V) oxide strontium chlorate strontium nitrate. Incompatible with lead dioxide, potassium chlorate, potassium nitrite may explode at elevated temperatures. On small fires, use smothering quantities of dry chemical powder, dry clay, dry groimd limestone (CaCOj), dry soda ash,dry sand or approved Class D extinguishers, do not use water, foam, or hydrous agents. 

To give the paper its colour eflect, after drying, take the sheets and steep them for five minutes in a warm saturated solution of strontium chlorate, or, better still, a lithium salt (for crimson) copper chlorate (for blue) barium chlorate (for green) i potassium nitrate (for violet) and afterwards hang themfip to dry. 

The alkaline earth metals can be detected in burning compounds by the colors that they give to flames. Calcium burns orange-red, strontium crimson, and barium yellow-green. Fireworks are often made from their salts (typically nitrates and chlorates, because the anions then provide an additional supply of oxygen) together with magnesium powder. 

Barium sulfide explodes weakly on heating with lead dioxide or potassium chlorate, and strongly with potassium nitrate. Calcium and strontium sulfides are similar. 

Mixtures with calcium hydride or strontium hydride may explode readily, and interaction of the molten chlorate is, of course, violent. A mixture of syrupy sodium phosphinate ( hypophosphite ) and the powdered chlorate on heating eventually explodes as powerfully as glyceryl nitrate. Calcium phosphinate mixed with the chlorate and quartz detonates (the latter producing friction to initiate the mixture). Dried mixtures of barium phosphinate and the chlorate are very sensitive and highly explosive under the lightest confinement (screwed up in paper).

Although Meyer s formulas are somewhat incoherent, they represent a definite advance. Equally significant with the use of chlorate is his use of the nitrates of strontium and barium. 

The second German edition of Ruggieri s book (we have not seen the first) contains a Nachtrag or supplement which lists nine compositions,10 of which four contain Kali oxym. or potassium chlorate. These are (1) for red fire, strontium nitrate 24 parts, sulfur 3, fine charcoal 1, and potassium chlorate 5 (2) for green fire, barium carbonate 20 parts, sulfur 5, and potassium chlorate 8 parts (3) for green stars, barium carbonate 20 parts, sulfur 5, and potassium chlorate 9 parts and (4) for red lances, strontium carbonate 24 parts, sulfur 4, charcoal 1, and potassium chlorate 4 parts. Ruggieri says ... 

Chemical ingredients of fireworks are chosen to produce specific colors. Barium compounds produce green colors when heated, copper salts produce green and blue flames, sodium salts are yellow in flame, lithium compounds produce red colors, magnesium metal produces brilliant white fight when burned, and strontium compounds produce brilliant red colors. Salts used contain both metallic cations and nonmetallic anions. Anions such as chlorates, perchlorates, and nitrates also contribute oxidizing power to the chemical mixture.

Uses In place of potassium chlorate in percussion primer compositions, with the object of prodneing noncorrosive primers, P4. Also in pyrotechnic compositions, in blasting explosives, and in some componnd propellants. See Double-Base Powders, E. C. Powder, Poudre B. N., Tonite, Strontium Nitrate, F8.

A solution of chlorate of strontium makes tho flash a bright crimson. Chlorate of barium, green. Nitrate of potassium, violet. Chlorate of copper, bluo. Any ono of tho foregoing chlorates may bo prepared by mixing a warm solution of tho corresponding chloride with an equivalent quantity of a warm solution of chlorate of potossa the precipitate formed will be chlorido of potassium, and tho clear liquid, poured off, will be the desired chlorate, to be used for saturating the gun-paper. 

Bed Fire. I, Forty parts of nitrate of strontium, 15 of sulphur, 5 of chlorate of potassium, and 2 of charcoal. 

II. Fifty parts of chlorate of potassium, 50 of nitrate of strontium 5 of charcoal and a sufficient quantity of linseed oil to knead the mass together. 

Bed Fire according to Bratmschtveig-er. Nine parts of nitrate of strontium, 3 of shellac. 1.5 of chlorate of potassium. The snellae need only be coarsely powdered. The above 3 mixtures for red fire possess the advantage of not emitting injurious vapors, and can therefore be used in rooms, etc.
