電(dian)(dian)(dian)(dian)導電(dian)(dian)(dian)(dian)極(ji)利用(yong)的(de)敏(min)感資料凡是為鉑，鍍鉑黑(hei)便是在鉑外表鍍上(shang)一層(ceng)玄(xuan)色疏松的(de)金屬鉑，目標是為了削減極(ji)化效(xiao)應(ying)。多孔(kong)的(de)鉑黑(hei)增添了電(dian)(dian)(dian)(dian)極(ji)的(de)外表積(ji)，使電(dian)(dian)(dian)(dian)流密(mi)度減小，使極(ji)化效(xiao)應(ying)變小，電(dian)(dian)(dian)(dian)容攪(jiao)擾也下降了。不鍍鉑黑(hei)或鍍得不好的(de)鉑黑(hei)電(dian)(dian)(dian)(dian)極(ji)，會發(fa)生很大(da)的(de)丈量偏差。鉑黑(hei)電(dian)(dian)(dian)(dian)極(ji)寄存時代要泡在蒸餾水(shui)(shui)中(zhong)不宜干放(fang)。若(ruo)是發(fa)明鉑黑(hei)電(dian)(dian)(dian)(dian)極(ji)凈(jing)化或生效(xiao)，可浸入10%硝(xiao)酸銀或酸洗水(shui)(shui)溶液(ye)中(zhong)二小時，之后(hou)用(yong)萃(cui)取水(shui)(shui)水(shui)(shui)蝕(shi)衛(wei)生再(zai)側(ce)量，鉑黑(hei)電(dian)(dian)(dian)(dian)級片還能(neng)(neng)夠從腳真(zhen)空(kong)鍍膜，但(dan)鍍鉑黑(hei)需用(yong)必然趨勢的(de)要求(qiu)和(he)成(cheng)長(chang)經歷，鍍黑(hei)層(ceng)鍍得好與壞對電(dian)(dian)(dian)(dian)級片后(hou)能(neng)(neng)有(you)更大(da)印象。
