Oxidation na Molybdenum Electrode

Molybdenum electrode yana da halayen juriya mai zafi, amma yana amsawa tare da oxygen a yanayin zafi. Lokacin da zafin jiki ya kai 400 ℃, damolybdenumzai fara samar da molybdenum oxidation (MoO) da molybdenum disulfide (MoO2), wanda zai iya manne da saman molybdenum electrode kuma ya samar da wani Layer na oxide, kuma ya tsara ƙarin oxidation na molybdenum electrode. Lokacin da zafin jiki ya kai 500 ℃ ~ 700 ℃, molybdenum zai fara oxidizing zuwa molybdenum trioxide (MoO3). Gas ne mai canzawa, wanda ke lalata shingen kariya na asali na oxide don sabon saman da aka fallasa ta molybdenum electrode ya ci gaba da yin oxidize don samar da MoO3. Irin wannan maimaitawar iskar shaka da juzu'i na sa molybdenum electrode ya ci gaba da lalacewa har sai ya lalace gaba daya.

 

Halin Molybdenum Electrode zuwa Bangaren Gilashin

Molybdenum electrode yana amsawa tare da wasu abubuwa ko ƙazanta a cikin ɓangaren gilashin a yanayin zafi mai zafi, yana haifar da mummunan yazawar lantarki. Alal misali, maganin gilashin tare da As2O3, Sb2O3, da Na2SO4 a matsayin mai bayyanawa yana da matukar tsanani ga lalatawar lantarki na molybdenum, wanda za a yi oxidized zuwa MoO da MoS2.

Sakamakon electrochemical yana faruwa a cikin gilashin lantarki, wanda yake a wurin haɗin sadarwa tsakanin molybdenum electrode da narkakken gilashin. A cikin ingantacciyar zagayowar rabin wutar lantarki ta AC, ana tura ions na iskar oxygen mara kyau zuwa na'urar lantarki mai kyau don sakin electrons, wanda ke sakin oxygen don haifar da iskar oxygen ta molybdenum. A cikin wutar lantarki na AC mara kyau na rabin zagaye, wasu daga cikin gilashin narke cations (kamar boron) za su matsa zuwa madaidaicin electrode da kuma samar da mahadi na molybdenum electrode mahadi, wadanda ke kwance a cikin farfajiyar lantarki don lalata wutar lantarki.

 

Zazzabi da yawa na yanzu

Yawan lalacewa na molybdenum electrode yana ƙaruwa tare da karuwar zafin jiki. Lokacin da abun da ke ciki na gilashin da zafin jiki na tsari ya tsaya tsayin daka, ƙimar yanzu ta zama abin da ke sarrafa ƙimar lalata na lantarki. Ko da yake matsakaicin adadin ƙuri'a na yanzu na molybdenum na lantarki zai iya kaiwa 2 ~ 3A/cm2, za a ƙara lalata wutar lantarki idan babban halin yanzu yana gudana.
