Cobalt ndi chitsulo chonyezimira chachitsulo chotuwa, cholimba komanso chosasunthika, ferromagnetic, komanso chofanana ndi chitsulo ndi faifi tambala mu kuuma, kulimba kwamphamvu, makina amakina, katundu wa thermodynamic, ndi machitidwe a electrochemical.Maginito amatha kutenthedwa mpaka 1150 ℃.Ufa wabwino wachitsulo wa cobalt wopangidwa ndi njira yochepetsera haidrojeni ukhoza kuyatsa modzidzimutsa mu cobalt oxide mumlengalenga.Oxidation imachitika pa kutentha kwakukulu.Akatenthedwa, cobalt imachita mwamphamvu ndi mpweya, sulfure, klorini, bromine, ndi zina zotero, kupanga mankhwala ofanana.Cobalt amasungunuka mu ma asidi osungunuka ndipo amalowetsedwa mu fuming nitric acid popanga filimu ya oxide.Cobalt imakhazikika pang'onopang'ono ndi hydrofluoric acid, ammonia ndi sodium hydroxide.Cobalt ndi chinthu chofunikira kwambiri popanga ma alloys osagwira kutentha, ma alloys olimba, anti-corrosion alloys, maginito aloyi ndi mchere wosiyanasiyana wa cobalt.Cobalt ndi chitsulo cha amphoteric.

Zomwe zimapangidwira komanso zamankhwala za cobalt zimatsimikizira kuti ndizofunikira kwambiri popanga ma alloys osagwira kutentha, simenti ya carbide, anti-corrosion alloys, maginito aloyi ndi mchere wosiyanasiyana wa cobalt.Cobalt-based alloy kapena cobalt-containing alloy steel imagwiritsidwa ntchito ngati masamba, zotulutsa, ma conduits, injini za jet, injini za rocket, zida za missile ndi zida zosiyanasiyana zolimbana ndi kutentha kwambiri pazida zamankhwala ndi zida zofunika zachitsulo mumakampani opanga mphamvu za atomiki.Cobalt ngati chomangira mu zitsulo zamafuta amatha kuwonetsetsa kuti carbide yopangidwa ndi simenti imakhala yolimba.Magnetic alloys ndi zinthu zofunika kwambiri m'mafakitale amakono amagetsi ndi ma electromechanical, omwe amagwiritsidwa ntchito popanga zida zosiyanasiyana za ma acoustic, optical, magetsi ndi maginito.Cobalt ndi gawo lofunikira la maginito okhazikika a maginito.M'makampani opanga mankhwala, cobalt amagwiritsidwa ntchito kuwonjezera pa ma superalloys ndi anti-corrosion alloys, komanso magalasi achikuda, pigments, enamel ndi catalysts, desiccant ndi zina zotero.Kuphatikiza apo, kugwiritsa ntchito cobalt kumakhala ndi chiwopsezo chachikulu kwambiri pagawo la batri.

Cobalt yachitsulo imagwiritsidwa ntchito makamaka popanga ma alloys.Cobalt base alloy ndi mawu wamba aloyi imodzi kapena zingapo zopangidwa ndi cobalt ndi chromium, tungsten, chitsulo ndi faifi tambala.Chitsulo chachitsulo chokhala ndi kuchuluka kwa cobalt chitha kupititsa patsogolo kukana komanso kudula kwachitsulo.Starlite carbide yomwe ili ndi cobalt yoposa 50% sidzataya kuuma kwake koyambirira ngakhale itatenthedwa mpaka 1000 ° C, ndipo tsopano carbide iyi yakhala chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito pakati pa zida zodulira golide ndi aluminiyamu.Munkhaniyi, cobalt imaphatikiza mbewu zina zachitsulo za carbide mu kapangidwe ka aloyi, kuti aloyiyo ikhale yolimba kwambiri komanso imachepetsa kukhudzidwa.Aloyi iyi imasakanikirana ndikuwotchedwa pamwamba pazigawo, zomwe zimatha kuwonjezera moyo wa ziwalozo ndi 3 mpaka 7.Ma alloys omwe amagwiritsidwa ntchito kwambiri muukadaulo wazamlengalenga ndi aloyi opangidwa ndi nickel, ndipo ma alloys opangidwa ndi cobalt angagwiritsidwenso ntchito, koma "makina amphamvu" a aloyi awiriwa ndi osiyana.Mphamvu ya ma aloyi a faifi tambala okhala ndi titaniyamu ndi aluminiyamu ndi yayikulu chifukwa cha mapangidwe a gawo lowumitsa lomwe limapangidwa ndi NiAl (Ti), pomwe kutentha kwa ntchito kuli kwakukulu, tinthu tating'onoting'ono timasamutsidwa ku yankho lolimba, ndiye aloyi mwamsanga amataya mphamvu.Kukana kutentha kwa cobalt-based alloys ndi chifukwa cha mapangidwe a carbides okana, omwe sali ophweka kuti asanduke njira zolimba, ndipo ntchito yofalitsa ndi yochepa.Kutentha kukakhala pamwamba pa 1038 ° C, ubwino wa ma aloyi opangidwa ndi cobalt amawonetsedwa bwino.Chifukwa chapamwamba kwambiri, injini zotentha kwambiri, ma alloys opangidwa ndi cobalt ndi olondola.
