Impushana emhlophe noma ekhanyayo ephuzi, emnandi futhi enobuthi ene-gravity ethize engu-6.1 kanye ne-refractive index 2.25.Ayikwazi ukuncibilika emanzini, kodwa ingancibilika ku-hydrochloric acid ne-nitric acid. Iphenduka ibe mpunga futhi ibe mnyama ku-200 ℃ iphenduke iphuzi ku-450 ℃, futhi inokudonswa okuhle.Iyi-antioxidant inokusebenza okuhle kakhulu kokumelana nemisebe ye-ultraviolet nokuguga.
