Superconductors is one of purposes for Srontium carbonate powderSrCO3 CAS NO 1633-05-2
►Description
Strontium carbonate is a white, odorless,tasteless powder.Being a carbonate,
it is a weak base and therefore is reactive with acids. It is otherwise stable and safe
to work with. It is practically insoluble in water (1 part in 100,000). The solubility is
increased significantly if the water is saturated with carbon dioxide, to 1 part in
1,000. It is soluble in dilute acids.
Other than the natural occurrence as a mineral, strontium carbonate is
prepared synthetically in one of two manners. First of which is from naturally
occurring celestine also known as strontium sulfate (SrSO4) or by using soluble
strontium salts by the reaction in solution with a soluble carbonate salt (usually
sodium or ammonium carbonates).
For example if sodium carbonate was used in solution with strontium nitrate:
Sr(NO3)2 + Na2CO3 → SrCO3 + 2 NaNO3

►Types of powder
Strontium carbonate coarse powder is used in the production of glazes, frits
and for production of strontium pigments. Another application for strontium
carbonate coarse powder is the production of special glass.
Strontium carbonate fine powder is used in the production of ferrites for
permanent magnets, and in Zinc electrolysis for removal of lead. Strontium
carbonate fine powder is also used in the production of strontium chromate.
Strontium carbonate granular is used in the production of display glass and
other glass. Strontium carbonate granular is also used in the metallurgy.
Strontium carbonate standard powder is used in the production of ferrites for
permanent magnets. Strontium carbonate standard powder is also used for the
production of glazes and enamel frits.
►Application
Strontium carbonate is also used for making some superconductors such as
BSCCO and also for electroluminescent materials where it is first calcined into SrO
and then mixed with sulphur to make SrS:x where x is typically europium. This is
the famous "blue/green" phosphor which is sensitive to frequency and changes
from lime green to blue Other dopants can also be used such as gallium, or yttrium
to get a yellow/orange glow instead.

Eye Contact: Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used.
Skin Contact: After contact with skin, wash immediately with plenty of water.
Gently and thoroughly wash the contaminated skin with running water and non-
abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cover the irritated skin with an emollient. If irritation persists, seek medical
attention.
Serious Skin Contact: Not available.
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate
medical attention.
Serious Inhalation: Not available. Ingestion: Do not induce vomiting. Loosen tight
clothing such as a collar, tie, belt or waistband. If the victim is not breathing,
perform mouth-to-mouth resuscitation. Seek immediate medical attention.
