Boehmite: Minɛri jɔnjɔn dɔ bɛ Aluminiyɔmu-fɛnw na minnu sinsinnen bɛ fɛnw kan

Boehmite, n’a ka kemikaliya formula -AlO(OH), ye aluminiyɔmu idɔrɔkisidi minɛn nafama ye min bɛ aliminiyɔmu ɔkisidi ka tɛmɛsira layɛrɛlen na. A fɔlɔ bɔra bouxite la san 1927 Alemaɲi kemikɛla Johann Boehm fɛ ani a ye a kristalɛ jɔcogo sɛgɛsɛgɛ cogo labɛnnen na, o de y’a tɔgɔ sɔrɔ. I n’a fɔ cɛmancɛ jɔnjɔn ye aliminiyɔmu fɛnɲɛnamafagalanw na minnu bɛ sɔrɔ fɛnɲɛnamaw ni fɛn dilannenw na, boehmite jɔyɔrɔ ka bon kosɛbɛ izini katalizi la, seramiki kɔrɔlenw na, ani litiyɔmu-ion batiriw la.

Kristalografu siratigɛ la, boehmite bɛ kristalo orthorhombique sitɛmu kɔnɔ. A jɔcogo jɔnjɔn ye aliminiyɔmu ɔkisidi octahedral layers ye minnu bɛ ɲɔgɔn cɛ ni hydroxyl bridges ye, ni interlayers (yɔrɔ cɛmancɛw) bɛ pake kosɛbɛ ni hydrogène bonds ye. O mikro-yɔrɔ kɛrɛnkɛrɛnnen in b’a to a ka yɔrɔ kɛrɛnkɛrɛnnen ka bon ani a ka funteni sabatili. Ni funteni ka bon-funteni na (degere 450–600 ɲɔgɔn ), a bɛ se ka wuli ka kɛ -Al2O3 (korondum) ye, o b’a kɛ ɲɛbila ɲuman ye ka ɲɛsin fɛnw labɛnni ma minnu fanga ka bon-. Sigida la, boehmite bɛ sɔrɔ tuma caman na i n’a fɔ fɛn misɛnninw kosɛbɛ tropical weathering crust-type bauxite kɔnɔ, u ni kaolinite ni gibbsite bɛ ɲɔgɔn fɛ. Nka.

Bi fɛɛrɛ kuraw ye boehmite ka baarakɛcogo caya. Enerji mobili kura seko ni dɔnko siratigɛ la, nanoscale boehmite, k’a sababu kɛ a ka kuran sɔgɔli ɲuman ye ani a ka kemikaliya baarakɛbaliya, a bɛ kɛ kosɛbɛ i n’a fɔ litiyamu batiri faranfasilanw datugulan, o bɛ batiri lakanani ɲɛ kosɛbɛ ani ka dendɛrɛsi falenni bali. Lamini katalizi la, a ka Lewis asidi yɔrɔ caman bɛ nɛgɛ gɛlɛnw ionw minɛ ka ɲɛ, wa u bɛ kɛ ka nɔgɔw bali ka lamaga jiko juguw furakɛli la. Boehmite fana ye fɛn fɔlɔ ye min bɛ kɛ ka molekiyɔmu sizow ni galasi kɛrɛnkɛrɛnnenw dilan, wa a ka baarakɛcogo nɔgɔman b’a kɛ fɛn ɲuman ye min bɛ kɛ ka fɛnw ta minnu bɛ kɛ ni kemikɛli ye.

Ni fɛnw dɔnniya bɛ ka taa ɲɛ ka ɲɛsin fɛnw labɛnni ma, boehmite ka baarakɛcogo caman bɛ ka taa a fɛ ka mɔgɔw hakili sama. Fɛn nataw minnu bɛna kɛ doping, modification, ani morphology control fɛɛrɛw la, olu bɛna dɔ fara nin fɛnɲɛnamafagalan kɔrɔ in nafa kan ka taa a fɛ izini fɛɛrɛbɔlenw na minnu bɛ ka bonya i n’a fɔ fanga marali ani sigida labɛnni.
