Magnesia vs. Magnesium: Know the Difference
By Shumaila Saeed || Published on January 28, 2024
"Magnesia" refers to magnesium oxide or hydroxide, used medicinally or industrially, while "Magnesium" is a lightweight, reactive chemical element (Mg).
Key Differences
Magnesia, often in the form of magnesium oxide or hydroxide, is used in medicine for its antacid properties. Magnesium, on the other hand, is a silver-white metallic element used in alloys.

Magnesium
A light, silvery-white, moderately hard metallic element that in ribbon or powder form burns with a brilliant white flame. Obtained chiefly from magnesite, dolomite, and bodies of salt water, it is used in structural alloys, pyrotechnics, flash photography, and incendiary bombs. Atomic number 12; atomic weight 24.305; melting point 650°C; boiling point 1,090°C; specific gravity 1.738 (at 20°C); valence 2. See Periodic Table.

Magnesium
A light silver-white metallic element of atomic number 12, malleable and ductile, quite permanent in dry air but tarnishing in moist air. It burns, forming (the oxide) magnesia, with the production of a blinding light (the so-called magnesium light) which is used in signaling, in pyrotechny, or in photography where a strong actinic illuminant is required. Its compounds occur abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg. Atomic weight, 24.305. Specific gravity, 1.75.
