產品描述

Strontium carbonate is a kind of nonpoisonous and tasteless white powdery crystal. Its molecular formula is SrCO3 and its molecular weight, density and melting point is 147.23, 3.7 and 1479 o respectively. The main products of our company include: powdery strontium carbonate, dry granular strontium carbonate and wet granular strontium carbonate. The strontium carbonate is not only the basic raw materials for producing other kinds of Strontium Salts, but the important raw materials for producing optical glass, color display tube, magnetic material, fireworks, pottery, dyestuff, painting, etc.

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.
