Is magnesium oxide toxic?

Toxic. If taken by mistake, it will lead to diarrhea and dehydration.






1. Magnesium oxide stimulates the mucous membrane to cause conjunctivitis and rhinitis. The concentration of magnesium oxide fume inhaled by human is 4-6mg / m3. For one to two minutes, metal fume fever can occur. The patient has fever, cough, chest compression, and leukocyte increase significantly.


2. Eating by mistake is harmful and may cause allergy. Avoid inhalation of gas or dust. Use in a well ventilated place. Avoid contact with eyes, skin or clothing. Please clean thoroughly after use and make sure the container is closed.

5. Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in nature as periclase and is the raw material of magnesium smelting.






6. Magnesium oxide has high fire resistance and insulation performance. It can be transformed into crystal by high temperature burning above 1000 ℃. When it rises to 1500-2000 ℃, it will become dead burned or sintered magnesia.
