Cobalt Oxide Co3O4 hupfu

Tsanangudzo

1.Zita: nanoCobalt oxideCo3O4 hupfu
2.Kuchena: 99.9% min
3.Appearacne: grey poda yakasviba
4.Particle size: 50nm

5.SSA: 30-80 m2/g

Properties:
Kuratidzira kumhepo, nyore kutora unyoro, asi haiburitse masanganiswa emvura. Inonyungudika mu nitric acid. Kana ichipisa kusvika pamusoro pe1200 oC, nano-cobalt oxide inoputsika kuita sub-cobalt oxide. Mumoto wehydrogen, nano-cobalt oxide inopisa kusvika 900 oC, inoshandurwa kuita simbi cobalt. Cobalt(II,III) oxide ikemikari inosanganiswa neformula Co3O4. Iyo yakasviba yakasimba, uye yakasanganiswa valence komisheni, ine zvese Co (II) uye Co (III) oxidation nyika. Inogona kugadzirwa seCoIICoIII2O4 kana CoO.Co2O3. Cobalt(II) oxide, CoO, inoshandura kuCo3O4 kana ichipisa kusvika ku600-700 °C mumhepo. Pamusoro pe900 °C, CoO yakagadzikana.

Application: 

Catalysis, superconductors, ceramics nedzimwe minda sechinhu chakakosha inorganic zvinhu; Sezvinoita uye catalyst mutakuri uye electrode inoshanda zvinhu; Kwegirazi, porcelain colorants uye pigments; Chemical industry oxidant uye catalyst ye organic synthesis; Magogi makuru uye zvimwe sefa zvinhu; Carbide; Tembiricha uye gasi sensors; Kune iyo semiconductor indasitiri, zvemagetsi ceramics, lithium ion bhatiri electrode zvinhu, magineti zvinhu; Electrochromic zvishandiso; Enamels; Kukuya mavhiri; Heterogeneous catalysts; Solar energy absorbers....
