Product Description
Product: Magnesium oxide
traits:
White fine powder. Without odour. Preparation methods for
different, there is light and heavy cent. In the visible and nearly
ultraviolet light within the area of strong refraction. Dew buy air
is easy to absorb water and carbon dioxide and gradually become
alkali type magnesium carbonate, light a heavy faster, and water
with magnesium hydroxide formation, a slightly alkaline reaction,
saturated solution pH *0.3. Soluble in dilute acid, hardly soluble
in water, because of the existence of the carbon dioxide and
increase its solubility. Not soluble in alcohol. The relative
density (d**4) 3.*8. Melting point ***2 ℃. Boiling point ***0
