Boehmite lossis böhmite yog aluminium oxide hydroxide (γ-AlO (OH)) ntxhia, ib feem ntawm txhuas aluminium bauxite. Nws yog dimorphous nrog diaspore.Nws yog dawb nrog tints daj, ntsuab, xim av lossis xim liab vim yog tsis huv. Nws muaj vitreous rau pearly luster, Mohs hardness ntawm 3 txog 3.5 thiab qhov nqus tshwj xeeb ntawm 3.00 txog 3.07. Nws tsis muaj xim nyob rau hauv ntu nyias, optically biaxial zoo nrog qhov ntsuas tsis pom ntawm nα=1.644 - 1.648, nβ=1.654 - 1.657 thiab nγ=1.661 - 1.668.
Boehmite tshwm sim nyob rau sab hnub tuaj teb chaws sov thiab bauxites tsim ntawm alumino-silicate txaj. Nws kuj tshwm sim raws li cov khoom hloov pauv dej ntawm corundum thiab nepheline. Nws tshwm sim nrog kaolinite, gibbsite thiab diaspore hauv bauxite tso nyiaj; thiab nrog nepheline, gibbsite, diaspore, natrolite thiab analcime hauv nepheline pegmatites. [3] Kev tsim khoom, nws tau siv los ua cov nplaim hluav taws uas pheej yig ntxiv rau cov hluav taws uas muaj kev nyab xeeb. Peb tuaj yeem tsim thiab kho boehmite raws li koj xav tau cov ntaub ntawv.
