Claims (10)
- Sestav inertne anode Patentni zahtevki1. Elektrolizni aparat, ki obsega sistem inertne anode, ki obsega vsaj eno inertno anodo, ki ima spodnji del, ki je v stiku s kadjo s staljeno soljo, kjer je vsaj zgornji del inertne anode v stiku s trdnim materialom in ga le-ta obdaja, ki je izpostavljen delovanju plinov iz kopeli, pri čemer je trdni material izbran iz skupine, ki sestoji iz cementa na osnovi aluminijevega oksida in kriolit-aluminijevega oksida, ki se oba raztopita v prisotnosti kopeli staljene soli.
- 2. Elektrolizni aparat po zahtevku 1, kjer trdni material vsebuje od okoli 40 mas. % do 80 mas. % kriolita, od okoli 2 mas. % do 25 mas. % aluminijevega oksida in od 5 mas. % do 25 mas. % cementnega materiala.
- 3. Elektrolizni aparat po zahtevku 1 ali zahtevku 2, pri čemer je elektrolizni aparat elektrolitska celica, primerna za proizvodnjo aluminija.
- 4. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer se trdni material raztopi do te mere, da je preostala gostota trdnega materiala od 30 % do 80 % prvotne nosilne gostote.
- 5. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer se trdni material raztopi do te mere, da je preostala gostota trdnega materiala od 40 % do 70 % prvotne nosilne gostote.
- 6. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer je material cementa proti vročini odporen cement na osnovi aluminijevega oksida.
- 7. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer je celotna vsaj ena inertna anoda obdana s trdnim materialom.
- 8. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer se trdni material nanese z ulivanjem.
- 9. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer se trdni material nanese z naprševanjem.
- 10. Elektrolizni aparat po katerem koli predhodnem zahtevku, pri čemer se trdni material nanese s potapljanjem.
