Aln tej hub seev hauv cov chaw muaj teeb meem
Aluminium Nitride (Aln) cov tub ceramion qhia qhov tshwj xeeb corrosion corrosion, tab sis lawv cov kev ua tau zoo nyob ntawm ib puag ncig thiab cov khoom siv purity:
Cov ntsiab lus tseem ceeb
Tshuaj lom neeg inertness
Ua kom tsis txhob acids (hco₃) txog 80 degree thiab alkalis (Naoh) qis dua 40 Degree -SuperIn rau cov hlau tab sis me ntsis tsis muaj zog dua li al₂o₃ hauv cov hauv paus muaj zog.
Kev tiv thaiv rau Halogen Gas Corrosion (cl au, F₂, F₂, F₂) nyob rau hauv semiconductor ntshav thiab lwm tus (txog 600 degree).
Oxidation tsis kam
Forms a protective Al₂O₃ surface layer at >800 degree nyob rau hauv huab cua, qeeb ntxiv degradation.
Molten Hlau Ua
Ruaj nyob hauv Molten Aluminium (660 degree) thiab tooj liab (1085 degree), outperforming quartz thiab graphite.
Txwv & mitigations
Poor performance in hot concentrated acids (e.g., H₂SO₄ >200 degree) → siv cov kab xyeem sic-coated aln rau huab.
Slow hydrolysis in steam >400 degree → siv rau y₂o ₃ txheej rau cov dej ib puag ncig.
Cov ntawv thov sab saum toj
: Cov Ntshav Lasma etcher Cheebtsam
Metallurgy: Thermocouple Shreighs hauv Molten Hlau
Kev Ua Lag Luam: Lub tsev nyob ntawm kev tawm tsam
Aln muab qhov zoo tshaj plaws-hauv-chav kawm thermal conductivity + corrosion tsis kam, ua rau nws zoo tagnrho rau kev muaj nyom thiab cov tshuab hnyav. Kev kho kom zoo rau kev pab cuam kom zoo tshaj 10 xyoo txawm tias nyob rau hauv kev ua kom nruj.
