monomer boron / amorphous boron hmoov CAS 7440-42-8
Boron muaj ntau yam allotropes. Amorphous boron kuj tseem hu ua elemental boron thiab monomer boron.
Nws yog hmoov xim av lossis cov siv lead ua xim grey ci ntsa iab, thiab nws cov khoom siv tshuaj lom neeg kuj muaj zog heev. Nws ruaj khov
nyob rau hauv huab cua thiab qhov kub thiab txias ib txwm muaj. Nws yog oxidized thaum rhuab mus rau 300 ℃ thiab hlawv ntawm 700 ℃, Lub nplaim taws
yog xim liab thaum hlawv, thiab nplaim boron nrog cov pa dej me me yog ntsuab. Insoluble hauv dej, hydrochloric
kua qaub, ethanol, thiab ether. Nws yog soluble nyob rau hauv txias concentrated alkali kua thiab decomposes hydrogen,
uas yog oxidized rau boric acid los ntawm concentrated nitric acid thiab concentrated sulfuric acid. Thaum siab
kub, Boron tuaj yeem cuam tshuam nrog oxygen, nitrogen, sulfur, halogens thiab carbon, Boron kuj tseem tuaj yeem
ncaj qha sib xyaw nrog ntau cov hlau los tsim cov borides. Cov tshuaj tiv thaiv ntawm boron nrog cov organic sib xyaw hauv
uas cov pa oxygen muaj nyob nruab nrab ntawm boron thiab carbon.
Ib qho boron nyob rau ntawm qhov chaw tshwj xeeb ntawm txoj kab faib ntawm cov hlau thiab cov hlau tsis yog hlau hauv
Lub rooj sib tham txog cov khoom. Nws yog ib qho khoom uas tsis yog hlau uas muaj lub zog tsis zoo, lub vojvoog atomic me me, muaj zog
Lub zog nuclear, thiab cov khoom tsis yog hlau zoo ib yam li sillicon. Nws qhov ceev yog 2.35g / cm3. Qhov nyuaj yog 9.3,
Qhov hnyav tshwj xeeb yog 2.33 - 2.45, qhov taw tes yaj 2300 ℃, qhov taw tes bolling 2550 ℃.
