Strontium Salts的详细介绍
(1) Strontium carbonate is a kind of nonpoisonous and tastelesswhite powdery crystal. Its molecular formula is SrCO3 and itsmolecular weight, density and melting point is 147.23, 3.7 and 1479o respectively. The main products of our company include: powderystrontium carbonate, dry granular strontium carbonate and wetgranular strontium carbonate. The strontium carbonate is not onlythe basic raw materials for producing other kinds of StrontiumSalts, but the important raw materials for producing optical glass,color display tube, magnetic material, fireworks, pottery,dyestuff, painting, etc.The qualitystandard and packaging of the industrial product of strontiumcarbonate

Packaging: Wet method granularstrontium carbonate and dry method granular strontium carbonateshall be packed in the plastic woven bags of 1000kg net weighteach, with plastic lining bags, or packed according to user'srequest. Powdery strontium carbonate shall be packed in the plasticwoven bags of 25kg or 600kg net weight each, with plastic liningbags, or packed according to user's request. |
| (2) Strontium nitrate is a kind of colorless or whiteshafting crystal with a relative density of 2.986 and a meltingpoint 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 furtherheated, the strontium nitrite produced will give off nitric oxideand 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 glassof the TV image tube. Besides, it can be used for making redfireworks and signal lamps of channels, railways, airports, etc. Ithas already been used by the national defense industry for makingthe 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 colorlessrod-like crystal with a relative density of1.93. It is easy todissolve in water, slightly dissolves in absolute ethyl alcohol andacetone, and does not dissolve in liquid ammonia. When thetemperature reaches 61.4o, it will lose 4 pieces of crystal waterand turn into SrCl2?2H20. When the temperature reaches 100o, itwill lose 5 pieces of crystal water and turn into SrCl2?H20. Whenthe temperature reaches 200o, it will lose 6 pieces of crystalwater and turn into absolute strontium nitrate which is the rawmaterials used for producing Strontium Salts and dyestuff. It canbe used for making fireworks, the fluxing agent of electrolyticmetal natrium as well as the catalyser of organic chemicalcompounding. |

| （4）The metal strontium is a kind of active metal which canreplace the hydrogen in water. It exists in the chemical compoundof Strontium Salts in the nature. Enjoying an active chemicalproperty and a strong reducibility, it is able to compound withnitrogen and so on. Besides, it is inflammable. In the metallurgytrade, metal strontium is often used as a kind of alterant toproduce strontium aluminum alloy, etc. Now, it has already beenwidely used in electron trade, aviation trade, automobile trade,etc. |
