<p><b>Halaman baru</b></p><div>'''Proses Hall-Héroult''' adalah proses yang digunakan untuk menghasilkan logam [[aluminium]] murni dari [[aluminium oksida]] di dalam [[smelter aluminium]]. Aluminium oksida yang telah dihasilkan dari [[proses Bayer]] dilarutkan ke dalam [[kriolit]] dan kemudian aluminium dihasilkan lewat proses [[elektrolisis]] lebur.<br />
<br />
== Sejarah ==<br />
Terdapat dua orang penemu yang menemukan proses ini secara terpisah pada tahun 1886, yaitu [[Charles Martin Hall]] dan [[Paul Héroult]]. Prosedur ini (dengan beberapa perbaikan) kini masih digunakan di bidang perindustrian.<br />
<br />
== Proses ==<br />
Sebelum proses [[elektrolisis]] lebur, aluminium oksida (titik lebur 2045&nbsp;°C) dicampur dengan [[kriolit]] (Na<sub>3</sub>[AlF<sub>6</sub>]) untuk menurunkan titik leburnya. Campuran yang dihasilkan (yang terdiri dari 80-90% kriolit) kini memiliki titik lebur 950&nbsp;°C, sehingga proses elektrolisis lebur pun menjadi dimungkinkan.<br />
<br />
Proses elektrolisisnya dapat disederhanakan seperti ini:<br />
<br />
[[Katode]]:<br />
:Al<sup>+3</sup> + 3 [[elektron|e<sup>−</sup>]] → Al<br />
<br />
[[Anoda]]:<br />
:O<sup>−2</sup> + C → [[karbon monoksida|CO]] + 2 e<sup>−</sup><br />
<br />
Secara keseluruhan:<br />
:Al<sub>2</sub>O<sub>3</sub> + 3 C → 2 Al + 3 CO<br />
<br />
Dalam kenyataannya, lebih banyak [[karbon dioksida|CO<sub>2</sub>]] yang dibentuk di anode daripada CO:<br />
:Al<sub>2</sub>O<sub>3</sub> + 3/2 C → 2 Al + 3/2 CO<sub>2</sub><br />
<br />
