kroomIIIoksiid
KroomIIIoksiid, also known as chromium(III) oxide and with the chemical formula Cr2O3, is a green, chemically stable oxide of chromium. It occurs naturally as the mineral eskolaite and is a common oxide of chromium in both natural and industrial contexts. Cr2O3 crystallizes in the corundum structure and has a very high melting point, making it resistant to heat and chemical attack. It is practically insoluble in water and largely inert to acids and bases under ordinary conditions.
Industrial production of Cr2O3 typically involves calcination of chromium(III) hydroxide or hydrated chromium oxide to form
Applications of chromium(III) oxide are driven by its vivid green color, chemical stability, and hardness. It
Cr2O3 is valued for its color stability and inertness, though handling considerations for powder forms include
