Superconductors is one of purposes for Srontium carbonate powderSrCO3 CAS NO 1633-05-2
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.
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.
