Boehmite Properties
Lintho tsa lik'hemik'hale
Bosoeu; ortho{0}rhomb; a=0.286 nm, b=1.2227nm, c{3}}nm; boima ke 3.5-4 Mohs; e fumanoe ka karabelo ea hydrothermal ea hydroxide slurries ka likhato tse 200 -250.
Boehmite ke aluminium oxide hydroxide (-AlO(OH))) mineral, e leng karolo ea aluminium ore bauxite. Ke ea tsamaiso ea orthorhombic 'me e na le mohaho o nang le lera. Karolong e 'ngoe le e 'ngoe ea sebopeho, li-ion tsa oksijene li hlophisitsoe ka li-cubic close-pakiloeng lithakong tsa octahedron, 'me li-ion tsa aluminium li fumaneha bohareng ba octahedron ho theha{4}}mohaho o habeli. , li-radicals tsa hydroxide li fumaneha holim'a mohaho o nang le lera, 'me lihlopha li kopantsoe ke li-hydrogen bond.
Lintho tsa 'mele
The most important aluminous minerals in bauxite are gibbsite (Al(OH)3), boehmite (AlO(OH)) and diaspore (AlO(OH)), however gibbsite requires lower digestion temperature to be dissolved (typically ~145oC) as compared to boehmite and diaspore (typically >240 oC), Equation (1 - 2). Ka hona, lihlahisoa tsa alumina hangata li etselitsoe ho sebetsana ka ho khetheha mofuta o le mong oa bauxite. Le hoja li-bauxite tsa boehmitic li atisa ho sebetsoa ka ho sebelisa maemo a 'mocheso o phahameng' (ho tsosolosa boehmite) ka khopolo ea boehmitic bauxite e ka sebetsoa ka semela se tlaase sa mocheso se nang le ts'ebetso e fokolang kapa e fokolang haeba maemo a boehmite a ne a le tlaase ka ho lekaneng, le hoja litaba tsena tsa boehmite li sa qhibilihe, ho eketsa masala a mangata ho hlakisa.

Tšebeliso ea Boehmite
Tlhahiso ea aluminium
Boehmite ke selelekela ts'ebetsong ea Bayer, moo e calcined ho hlahisa alumina. Joale alumina ena e qhibilihisoa ho ntša tšepe ea aluminium. Bohloeki ba boehmite bo ama ka ho toba katleho le boleng ba tlhahiso ea aluminium, e leng se etsang hore e be thepa ea bohlokoa e tala.
Li-Catalysts le li-petrochemicals
Lits'ebetsong tsa catalytic, boehmite e sebetsa e le thepa ea tšehetso. Sebaka sa eona se phahameng le botsitso ba mocheso li matlafatsa ts'ebetso ea li-catalyst, haholo-holo lits'ebetsong tsa ho hloekisa le tsa petrochemical. Sena se fella ka liphetoho tse sebetsang hantle tsa lik'hemik'hale le ho fokotsa litšenyehelo tsa ts'ebetso.
Ceramics & refractories
-Liphofshoana tsa boehmite tse hanyetsanang le mocheso o phahameng li sebelisoa ha ho etsoa litene tsa tšepe le likarolo tsa ceramic. Lisebelisoa tsena li mamella mocheso o feteletseng ka har'a libopi, liboping le li-reactors, ho netefatsa hore li tšoarella le ho sireletseha.
Li-polymers le metsoako
Boehmite e kenyelelitsoe matrices a polymer ho ntlafatsa botsitso ba mocheso le matla a mochine. Ts'ebeliso ena e thusa liindasteri tse kang tsa sefofane le tlhahiso ea likoloi, moo lisebelisoa tse bobebe empa tse tšoarellang li bohlokoa.
Electronics & insulation
Ka lebaka la thepa ea eona e sireletsang, boehmite e sebelisoa likarolong tsa elektronike le e le thepa ea dielectric. Ho tsitsa ha eona tlas'a khatello ea motlakase ho tiisa{1}}ts'ebetso e tšoarellang ea lisebelisoa.
