What is the difference between

The crystal shape is different. The chemical formula is MgO. The chemical properties are basically the same, at least not as large as between the two kinds of Al2O3 crystals.

Magnesium oxide light is also called industrial magnesium oxide. Light magnesium oxide is a white amorphous powder, non-toxic, odorless, tasteless, with a relative true density of about 3.58 (25 ℃), melting point of 2850 ℃, boiling point of 3600 ℃, insoluble in water, insoluble in alcohol, soluble in acid and ammonium salt solution. Light magnesium oxide can be transformed into crystal by high temperature burning above 1000 ℃. When the temperature rises above 1500 ℃, it will become dead burned magnesia or sintered magnesia. Absorb carbon dioxide from the air to produce light magnesium carbonate.

Light oxygen ZD magnesium can not be directly converted into heavy magnesium oxide.


----


The difference between heavy magnesium oxide and light magnesium oxide is as follows:


Production process: light magnesium oxide is generally from magnesium chloride, magnesium sulfate, or magnesium bicarbonate, into water-soluble products through chemical process into water-insoluble products, and then calcined into magnesium oxide. The bulk density of products produced is generally 0.2 (g / ml),


2. However, the heavy magnesium oxide is usually calcined directly from magnesite and brucite, and the bulk density is generally (g / ml) 0.5.
