Monomer boron / amorphous boron hmoov CAS 7440-42-8
Boron muaj ob peb allotropes. Amorphous boron tseem hu ua elemental boron thiab monomer boron.
Nws yog xim av hmoov los yog grey ci ci muaju, thiab nws cov khoom siv tshuaj muaj zog. Nws ruaj khov
nyob rau hauv huab cua thiab qhov kub thiab txias. Nws yog oxidized thaum rhuab mus rau 300 ℃ thiab kub hnyiab ntawm 700 ℃, Cov nplaim taws
yog liab thaum hlawv, thiab cov nplaim boron nrog cov kab vaporization yog ntsuab. Insoluble hauv dej, hydrochloric
acid, 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
Qhov kub thiab txias, Boron tuaj yeem cuam tshuam nrog oxygen, nitrogen, sulfur, halogens thiab carbon, Boron tuaj yeem ua tau
ncaj qha ua ke nrog ntau cov hlau los ua borides. Cov tshuaj tiv thaiv ntawm boron nrog cov organic tebchaw hauv
uas oxygen muaj nyob nruab nrab ntawm boron thiab carbon.
Ib leeg boron nyob ntawm ib txoj hauj lwm tshwj xeeb ntawm txoj kab sib faib ntawm cov hlau thiab cov hlau tsis muaj hlau nyob hauv
daim ntawv teev caij nyoog. Nws yog cov khoom tsis yog xim hlau nrog lub zog tsis zoo, me me atomic radius, concentrated
nuclear charge, thiab non-metallic zog zoo ib yam li silicon. Nws qhov ceev yog 2.35g / cm3. Hardness yog 9.3,
Lub ntiajteb txawj nqus tshwj xeeb yog 2.33 - 2.45, melting point 2300 ℃, bolling point 2550 ℃.
