Magnesium oxide bụ ahụkarị alkaline earth metal oxide, chemical usoro MgO.White ntụ ntụ, agbaze 2852 ℃, esi esi 3600 ℃, ikwu njupụta nke 3.58 (25 ℃).Ọ bụ soluble na acid na ammonium nnu ngwọta.Iji mmiri eme ihe ngwa ngwa nwere ike imepụta magnesium hydroxide.Enwere ike ịgbaze ya na ngwọta mmiri carbon dioxide iji mepụta magnesium bicarbonate.N'ikuku, ọ nwere ike jiri nwayọọ nwayọọ na-amịkọrọ mmiri na carbon dioxide.Igwe ọkụ na-ahapụ uzu ọkụ na-akpasu iwe.Magnesite (MgCO3), dolomite (MgCO3 • CaCO3) na mmiri mmiri bụ isi akụrụngwa maka mmepụta nke magnesium oxide.
Magnesium oxide na-ekewa n'ime ụdị abụọ nke ìhè magnesium oxide na nnukwu magnesium oxide.Ìhè magnesium oxide bụ lax na olu, ọcha amorphous ntụ ntụ.Enweghị isi, enweghị ụtọ na adịghị egbu egbu.Njupụta 3.58g/cm3.insoluble na mmiri dị ọcha na organic mgbaze.Olu magnesium oxide dị arọ bụ kọmpat, ọcha ma ọ bụ ntụ ntụ beige.The mepụtara mma magnesium oxide bụ tumadi eji maka elu ọkwa mmanu, elu ọkwa tanning akpụkpọ anụ ebuli alkali ọkwa, nri ọkwa, ọgwụ, silicon ígwè ọkwa, elu ọkwa electromagnetic ọkwa, elu ịdị ọcha magnesium oxide na fọrọ nke nta iri iche nke mejupụtara.
