ʻO ka Cobalt Tetroxide (Co 73%) a me ka Cobalt Oxide (Co 72%).

Cobalt (II) Oxideʻike ʻia me he ʻoliva ʻōmaʻomaʻo a ʻulaʻula paha, a i ʻole ka pauka hina a ʻeleʻele paha.Cobalt (II) Oxidehoʻohana nui ʻia i ka ʻoihana seramika ma ke ʻano he mea hoʻohui e hana i nā aniani polū a me nā enamels a me ka ʻoihana kemika no ka hana ʻana i nā paʻakai cobalt(II).
ʻO ka Cobalt(II) Hydroxide a i ʻole Cobaltous Hydroxide 99.9% (metala kumu)

Kobalt(II) Hydroxide or ʻO ka kobaltous hydroxidehe kumu wai hoʻoheheʻe ʻole ʻia ʻo Cobalt.He mea hoʻohuihui ʻole ia me ke ʻanoKo(OH)2, i loko o nā ʻāpana kobalt divalent Co2+ a me nā anions hydroxide HO−.Hōʻike ʻia ʻo Cobaltous hydroxide e like me ka pauka rose-ulaʻula, hiki ke hoʻoheheʻe ʻia i loko o nā waikawa a me nā paʻakai ammonium solution, hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me nā alkalies.
Cobaltous Chloride (CoCl2∙6H2O ma ke ano kalepa) Co assay 24%

ʻO ke Kloride Cobaltous(CoCl2∙6H2O ma ke ʻano kalepa), he paʻa ʻulaʻula e loli ana i ka polū i ka wā e maloʻo ai, hoʻohana ʻia i ka hoʻomākaukau ʻana i ka catalyst a ma ke ʻano he hōʻailona o ka haʻahaʻa.
Hexaamminecobalt(III) chloride [Co(NH3)6]Cl3 assay 99%

ʻO ka Hexaamminecobalt(III) Chloride he hui hoʻohui cobalt i loaʻa i kahi cation hexaamminecobalt(III) i hui pū me ʻekolu anion chloride ma ke ʻano he counterions.
