Magnesium oxide (MgO), lossis magnesia, yog cov xim dawb hygroscopic cov ntxhia uas tshwm sim ib yam li periclase thiab yog qhov chaw ntawm magnesium (saib kuj oxide). Nws muaj cov qauv ua piv txwv ntawm MgO thiab suav nrog lub lattice ntawm Mg2 {{2}} ions thiab O2− ions tuav ua ke los ntawm kev sib txuas ionic. Magnesium hydroxide cov ntawv nyob hauv dej (MgO + H2O → Mg (OH) 2), tab sis nws tuaj yeem thim rov qab los ntawm cua sov kom cais cov dej noo.

Magnesium oxide tau keeb kwm hu ua magnesia alba (txhais tau tias, cov ntxhia dawb los ntawm magnesia - lwm qhov chaw muab magnesia alba li MgCO3), txhawm rau sib txawv nws los ntawm magnesia negra, cov ntxhia dub uas muaj tam sim no hu ua manganese.

Thaum" magnesium oxide" ib txwm hais txog MgO, magnesium peroxide MgO2 tseem paub tias yog cov khoom sib xyaw. Raws li kev hloov pauv ntawm cov txheej txheem ua ntej kwv yees kwv yees, MgO2 yog cov khoom siv thermodynamically ruaj khov ntawm kev ntsuas siab dua 116 GPa (gigapascals), thiab tag nrho cov semiconducting suboxide Mg3O2 tshiab yog thermodynamically ruaj khov saum 500 GPa. Vim tias nws muaj kev ruaj ntseg, MgO tau siv los ua qauv txheej txheem rau kev tshuaj xyuas cov khoom muaj zog ntawm cov muaju.
