Izinto ezichaphazela uBomi beNkonzo yeMolybdenum Electrodes

 Ishishini leglasi lishishini lemveli elinokusetyenziswa kwamandla aphezulu. Ngexabiso eliphezulu lamandla efosili kunye nokuphuculwa kweemfuno zokhuseleko lokusingqongileyo, itekhnoloji yokunyibilika itshintshile ukusuka kwitekhnoloji yemveli yokufudumeza idangatye ukuya kubuchwephesha bokunyibilika kombane. I-electrode yinto edibana ngokuthe ngqo nolwelo lweglasi kwaye igqithise amandla ombane kulwelo lweglasi, eyona sixhobo sibalulekileyo kwi-electrofusion yeglasi.

 

I-Molybdenum electrode yimathiriyeli ye-electrode eyimfuneko kwiglasi ye-electrofusion ngenxa yamandla ayo obushushu obuphezulu, ukumelana nokubola, kunye nobunzima bokwenza umbala weglasi. Kuthenjwa ukuba ubomi benkonzo ye-electrode buya kuba bude bubude be-kiln okanye nangaphezulu kuneminyaka yobudala, kodwa i-electrode iya kuhlala yonakaliswa ngexesha lokusetyenziswa kwangempela. Kubaluleke kakhulu ukuyiqonda ngokupheleleyo imiba eyahlukeneyo echaphazela ubomi benkonzo ye-molybdenum electrode kwi-glass electro-fusion.

 

 

I-Oxidation ye-Molybdenum Electrode

I-electrode ye-molybdenum ineempawu zokumelana nobushushu obuphezulu, kodwa isabela nge-oksijini kumaqondo aphezulu. Xa ubushushu bufikelela kwi-400 ℃, imolybdenumiya kuqala ukwenza i-molybdenum oxidation (i-MoO) kunye ne-molybdenum disulfide (i-MoO2), enokuthi ibambelele kumphezulu we-electrode ye-molybdenum kwaye yenze i-oxide layer, kwaye iququzelele i-oxidation eyongezelelweyo ye-molybdenum electrode. Xa ubushushu bufikelela kwi-500 ℃ ~ 700 ℃, i-molybdenum iya kuqala i-oxidizing kwi-molybdenum trioxide (MoO3). Yigesi eguqukayo, eyonakalisa umaleko okhuselayo we-oxide yasekuqaleni ukuze indawo entsha evezwe yi-molybdenum electrode iqhubeke i-oxidize ukwenza i-MoO3. Ukuphindaphinda okunjalo kwe-oxidation kunye ne-volatilization kwenza i-electrode ye-molybdenum iqhube ngokuqhubekayo ide yonakaliswe ngokupheleleyo.

 

Ukusabela kweMolybdenum Electrode kwiCandelo kwiGlasi

I-electrode ye-molybdenum idibana namanye amacandelo okanye ukungcola kwilungu leglasi kumaqondo obushushu aphezulu, nto leyo ebangela ukhukuliseko olukhulu lwe-electrode. Ngokomzekelo, isisombululo seglasi kunye ne-As2O3, i-Sb2O3, kunye ne-Na2SO4 njengoko i-clarifier iyingozi kakhulu ekukhukuliseni i-electrode ye-molybdenum, eya kuba yi-oxidized kwi-MoO kunye ne-MoS2.

 

I-Electrochemical Reaction kwi-Glass Electrofusion

Ukusabela kwe-electrochemical kwenzeka kwi-electrofusion yeglasi, ekwi-interface yoqhagamshelwano phakathi kwe-electrode ye-molybdenum kunye neglasi etyhidiweyo. Kumjikelo wesiqingatha esilungileyo sobonelelo lwamandla e-AC, ii-ion ze-oksijini ezingakhiyo zikhutshelwa kwi-electrode efanelekileyo ukuze kukhululwe ii-electron, ezikhupha i-oksijini ukuze ibangele i-oxidation ye-electrode ye-molybdenum. Kumjikelo wamandla we-AC ongalunganga wesiqingatha somjikelo, ezinye zeglasi ezinyibilikayo zegesi (ezifana ne-boron) ziya kufudukela kwi-electrode engalunganga kunye nokuveliswa kweekhompawundi ze-electrode ze-molybdenum, eziziidiphozithi ezikhululekileyo kumphezulu we-electrode ukonakalisa i-electrode.

 

Ubushushu kunye nokuxinana kwangoku

Izinga lokukhukuliseka kwe-molybdenum electrode landa ngokunyuka kwamaqondo obushushu. Xa ukubunjwa kweglasi kunye nobushushu benkqubo buzinzile, ukuxinana kwangoku kuba yinto elawula izinga lokubola kwe-electrode. Nangona ubuninzi obuvumelekileyo obukhoyo be-electrode ye-molybdenum bunokufikelela kwi-2 ~ 3A / cm2, ukuchithwa kwe-electrode kuya kwandiswa ukuba umbane omkhulu usebenza.
