ʻO ka pigment hao ʻokikene kahi ʻano pigment me ka maikaʻi o ka hoʻolaha ʻana, ke kūpaʻa maikaʻi loa i ka mālamalama, a me ke kūpaʻa i ka wā. ʻO nā pigment hao ʻokikene e pili nui ana i ʻehā ʻano o nā pigment kala, ʻo ia hoʻi ka hao ʻokikene ʻulaʻula, ka hao melemele, ka hao ʻeleʻele, a me ka hao ʻeleʻele, ma muli o nā ʻokikene hao. I waena o lākou, ʻo ka hao ʻokikene ʻulaʻula ka pigment nui (e helu ana ma kahi o 50% o nā pigment hao ʻokikene), a ʻo ka mika hao ʻokikene i hoʻohana ʻia ma ke ʻano he pigment anti-rust a me ka magnetic hao ʻokikene i hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa magnetic e pili ana hoʻi i ka māhele o nā pigment hao ʻokikene. ʻO ka hao ʻokikene ka lua o ka pigment inorganic nui loa ma hope o ka titanium dioxide a ʻo ia hoʻi ka pigment inorganic kala nui loa. ʻOi aku ma mua o 70% o nā pigment hao ʻokikene i hoʻopau ʻia i hoʻomākaukau ʻia e nā ʻano hana synthesis kemika, i ʻike ʻia ʻo synthetic iron oxide. Hoʻohana nui ʻia ka synthetic iron oxide i nā mea kūkulu hale, nā uhi, nā plastics, nā mea uila, ka paka, ka lāʻau lapaʻau, ka rubber, nā keramika, ka ʻīnika paʻi, nā mea magnetic, ka hana pepa a me nā ʻoihana ʻē aʻe ma muli o kona maʻemaʻe synthetic kiʻekiʻe, ka nui o nā ʻāpana like, ka chromatography ākea, nā kala he nui, ke kumu kūʻai haʻahaʻa, ʻaʻohe ʻawaʻawa, nā waiwai kala a me nā noi maikaʻi loa, a me nā waiwai absorption ultraviolet. Hoʻohana nui ʻia nā pigment hao oxide i nā uhi, nā pena, a me nā ʻīnika ma muli o ko lākou ʻawaʻawa ʻole, ʻaʻole kahe koko, haʻahaʻa ke kumukūʻai, a me ka hiki ke hana i nā ʻano aka like ʻole. Hana ʻia nā uhi me nā mea hana kiʻiʻoniʻoni, nā pigment, nā mea hoʻopiha, nā mea hoʻoheheʻe, a me nā mea hoʻohui. Ua ulu aʻe ia mai nā uhi ʻaila a i nā uhi resin synthetic, a ʻaʻole hiki i nā uhi like ʻole ke hana me ka ʻole o ka hoʻopili ʻana o nā pigment, ʻoiai nā pigment hao oxide, i lilo i ʻano pigment pono ʻole i ka ʻoihana uhi.

ʻO nā pigment hao oxide i hoʻohana ʻia i nā uhi ʻana, ʻo ia ka melemele hao, ka ʻulaʻula hao, ka ʻeleʻele hao, ka ʻeleʻele hao, ka ʻokepa hao mika, ka melemele hao moakaka, ka ʻulaʻula hao moakaka, a me nā huahana translucent, ʻo ka ʻulaʻula hao ka mea nui loa i ka nui a me ka laulā.

He kūpaʻa wela maikaʻi loa ka hao ʻulaʻula, ʻaʻole ia e loli ke kala ma 500 ℃, a ʻaʻole hoʻi e loli kona ʻano kemika ma 1200 ℃, e lilo ia i mea paʻa loa. Hiki iā ia ke omo i ka spectrum ultraviolet i ka lā, no laila he hopena pale kona ma ka uhi ʻana. He kūpaʻa ia i nā waikawa dilute, alkalis, wai, a me nā mea hoʻoheheʻe, e lilo ia i kūpaʻa maikaʻi i ka wā.
