¡¡¡¡(2) Strontium nitrate is a kind of colorless or white shafting crystal with a relative density of 2.986 and a melting point of 570o. It is easy to dissolve in water and liquid ammonia, and can slightly dissolve in absolute ethyl alcohol and acetone. When heated, it will decompose and give off oxygen. When further heated, the strontium nitrite produced will give off nitric oxide and nitrogen dioxide and at last turn into strontia. When touching, rubbing and colliding with organic substances or meeting the fire, it will burn, explode and emit crimson flames. And it is poisonous. It is mainly used for producing the red luminophor and optic glass of the TV image tube. Besides, it can be used for making red fireworks and signal lamps of channels, railways, airports, etc. It has already been used by the national defense industry for making the signal flare, flame tracer and flame tube. In medical industry, it can be used for producing fluorophor

¡¡¡¡£¨3£©Strontium chloride hexahydrate is a kind of colorless rod-like crystal with a relative density of1.93. It is easy to dissolve in water, slightly dissolves in absolute ethyl alcohol and acetone, and does not dissolve in liquid ammonia. When the temperature reaches 61.4o, it will lose 4 pieces of crystal water and turn into SrCl2?2H20. When the temperature reaches 100o, it will lose 5 pieces of crystal water and turn into SrCl2?H20. When the temperature reaches 200o, it will lose 6 pieces of crystal water and turn into absolute strontium nitrate which is the raw materials used for producing Strontium Salts and dyestuff. It can be used for making fireworks, the fluxing agent of electrolytic metal natrium as well as the catalyser of organic chemical compounding.

¡¡¡¡£¨4£©The metal strontium is a kind of active metal which can replace the hydrogen in water. It exists in the chemical compound of Strontium Salts in the nature. Enjoying an active chemical property and a strong reducibility, it is able to compound with nitrogen and so on. Besides, it is inflammable. In the metallurgy trade, metal strontium is often used as a kind of alterant to produce strontium aluminum alloy, etc. Now, it has already been widely used in electron trade, aviation trade, automobile trade, etc.
