Chemistry of Chromium - Chemistry LibreTexts

The magnetic properties of chromium make it perfect for magnetic tapes. Chromium dioxide is used in recording tapes. Potassium dichromate has been used in the tanning of leather. Small trace quantities of chromium have been found in semiprecious stones including: rubies, sapphires, emeralds, serpentine and jade. Chromium is also used to line ovens and molds because of its high melting point ...

Mysterious Anomaly Under Africa Is Weakening .

Earth's magnetic field doesn't just give us our north and south poles; it's also what protects us from solar winds and cosmic radiation – but this invisible force field is rapidly weakening, to the point scientists think it could actually flip, with our magnetic poles reversing.. As crazy as that sounds, this actually does happen over vast stretches of time.
