Chidule cha cobalt tetroxide

Cobalt trioxide (Co3O4) ndi gulu lomwe lili ndi zinthu zabwino kwambiri zakuthupi komanso zamankhwala.Ndiwolimba wakuda, wosasungunuka m'madzi komanso wosasunthika ku mpweya ndi chinyezi.Chifukwa cha maginito ake okwera kwambiri, zochita zambiri zamakina komanso magwiridwe antchito apamwamba a electrochemical, cobalt tetroxide yakhala ikugwiritsidwa ntchito kwambiri mu mphamvu, zamagetsi, zopangira ndi zina.

Thupi ndi mankhwala katundu wa cobalt trioxide

Cobalt tetroxide ili ndi zinthu zabwino kwambiri zakuthupi.Ndiwolimba wakuda, wosasungunuka m'madzi komanso wosasunthika ku mpweya ndi chinyezi kutentha kutentha.Kachulukidwe ake ndi 5.12g/cm3, ndipo makhiristo ndi tetragonal oxides.Magnetism ndi khalidwe lofunika la cobalt tetroxide, yomwe imakhala ndi maginito apamwamba ndipo ingagwiritsidwe ntchito muzinthu zamagetsi ndi zina.

Pankhani ya mankhwala, cobalt tetroxide imakhala ndi zochita zambiri zama mankhwala.Ikhoza kuchepetsedwa kukhala cobalt zitsulo kapena oxidized kukhala cobalt dioxide.Kuphatikiza apo, cobalt tetroxide idzawola pansi pa kutentha kwambiri komanso kuwala.

Kupanga ndi kaphatikizidwe njira ya cobalt trioxide

Pali njira zambiri zopangira cobalt tetroxide, njira zazikuluzikulu zikuphatikizapo kaphatikizidwe kagawo, kaphatikizidwe kamadzimadzi ndi kaphatikizidwe kagasi.Pakati pawo, njira yolimba yaphatikizidwe ndiyo njira yomwe imagwiritsidwa ntchito kwambiri.Amapangidwa ndi zitsulo za cobalt kapena cobalt hydroxide ngati zopangira, ndipo amawotchedwa ndi mpweya wotentha kwambiri kuti apeze cobalt tetroxide.

Malo ogwiritsira ntchito kwambiri a cobalt tetroxide

Chifukwa cha mphamvu zake zapadera komanso mankhwala, cobalt tetroxide yakhala ikugwiritsidwa ntchito kwambiri m'madera ambiri.Mwa iwo, gawo lofunikira kwambiri logwiritsira ntchito ndilo gawo lothandizira.Cobalt tetroxide ingagwiritsidwe ntchito ngati chothandizira pazochitika zosiyanasiyana, monga cyclopropanation reaction, oxidation reaction, alkylation reaction, etc. Kuphatikiza apo, cobalt tetroxide ingagwiritsidwenso ntchito mu zipangizo za batri, maginito, zipangizo zamagetsi ndi zina.
