Titanium Mixed hlau oxide electrode
Mixed hlau oxide (MMO) electrodes, tseem hu ua Dimensionally Stable Anodes (DSA), yog cov khoom siv nrog cov khoom siv hluav taws xob siab thiab corrosion kuj siv los ua anodes hauv electrolysis. Lawv yog tsim los ntawm txheej txheej substrate, xws li ntshiab titanium phaj los yog nthuav mesh, nrog ob peb hom hlau oxides. Ib qho oxide feem ntau yog RuO2, IrO2, lossis PtO2, uas ua hluav taws xob thiab ua rau cov tshuaj tiv thaiv uas xav tau xws li tsim cov roj chlorine. Lwm cov hlau oxide feem ntau yog titanium dioxide uas tsis ua lossis catalyze cov tshuaj tiv thaiv, tab sis pheej yig dua thiab tiv thaiv sab hauv corrosion.
Kev thauj khoom lossis tus nqi ntawm cov hlau muaj txiaj ntsig ntawm lub substrate (uas yog, tsis yog titanium) tuaj yeem nyob rau hauv qhov kev txiav txim ntawm 10 mus rau 12 grams ib square meter.[1]

Daim ntawv thov
Cov ntawv thov suav nrog kev siv anodes hauv electrolytic hlwb los tsim cov tshuaj dawb dawb los ntawm cov dej ntsev hauv cov pas dej da dej, hauv electrowinning ntawm cov hlau, hauv kev tsim khoom siv hluav taws xob, electrowinning thiab zinc electro-galvanising ntawm steel, raws li anodes rau cathodic tiv thaiv ntawm faus los yog submerged lug.
Keeb kwm
Henri Bernard Beer tau sau npe nws daim ntawv pov thawj ntawm cov hlau oxide electrodes sib xyaw hauv xyoo 1965.[2] Lub npe patent hu ua "Beer 65", tseem hu ua "Beer I", uas Npis tau lees tias qhov tso tawm ntawm Ruthenium oxide, thiab sib xyaw cov titanium soluble rau cov xim, txog li 50% (nrog feem pua molar RuO2:TiO{{5}). }:50). Nws thib ob patent, Beer II, [3] txo cov Ruthenium oxide cov ntsiab lus hauv qab 50%.[4]
