Boron ndi metalloid element, yokhala ndi ma allotropes awiri, amorphous boron ndi crystalline boron. Amorphous boron ndi ufa wofiirira pomwe crystalline boron ndi silvery mpaka wakuda. Ma crystalline boron granules ndi zidutswa za boron ndizoyera kwambiri, zolimba kwambiri, ndipo sizimayendetsa bwino kutentha.
Crystalline Boron
Mtundu wa kristalo wa boron wa crystalline makamaka ndi β-mawonekedwe, omwe amapangidwa kuchokera ku β-mawonekedwe ndi γ-mawonekedwe kukhala kyubu kuti apange mawonekedwe okhazikika a kristalo. Monga crystalline boroni yochitika mwachilengedwe, kuchuluka kwake kumapitilira 80%.Mtundu wake nthawi zambiri umakhala ufa wofiirira kapena tinthu tating'ono tomwe timapanga tofiirira. The ochiritsira tinthu kukula kwa crystalline boron ufa opangidwa ndi makonda ndi kampani yathu ndi 15-60μm; wamba tinthu kukula crystalline boron particles ndi 1-10mm (wapadera tinthu kukula akhoza makonda malinga ndi zosowa za kasitomala). Nthawi zambiri, imagawidwa m'magulu asanu molingana ndi chiyero: 2N, 3N, 4N, 5N, ndi 6N.

Amorphous Boron
Amorphous boron amatchedwanso non-crystalline boron. Mawonekedwe ake a kristalo ndi owoneka ngati α, amtundu wa tetragonal crystal, ndipo mtundu wake ndi wakuda bulauni kapena wachikasu pang'ono. Amorphous boron ufa wopangidwa ndi makonda ndi kampani yathu ndi mankhwala apamwamba kwambiri. Pambuyo pokonza mwakuya, zomwe zili ndi boron zimatha kufika 99%, 99.9%; kukula kwa tinthu tating'ono ndi D50≤2μm; malinga ndi kukula kwa tinthu tapadera kwa makasitomala, ufa wa sub-nanometer (≤500nm) ukhoza kukonzedwa ndikusinthidwa makonda.

Kodi Amorphous boron, Boron powder ndi Natural boron amagwiritsidwa ntchito chiyani?
Pali ntchito zambiri za Amorphous boron, Boron ufa ndi Natural boron. Amagwiritsidwa ntchito muzitsulo, zamagetsi, mankhwala, zoumba, mafakitale a nyukiliya, makampani opanga mankhwala ndi zina.
1. Amorphous boron amagwiritsidwa ntchito m'makampani opanga magalimoto monga choyatsira m'matumba a airbags ndi zomangira lamba. Amorphous boron amagwiritsidwa ntchito mu pyrotechnics ndi maroketi ngati chowonjezera mu flares, zoyatsira ndi nyimbo zochedwetsa, mafuta olimba opangira mafuta, ndi zophulika. Zimapatsa ma flares mtundu wobiriwira wosiyana.
2. Boroni yachilengedwe imapangidwa ndi isotopu ziwiri zokhazikika, imodzi mwa izo (boron-10) imakhala ndi ntchito zingapo monga nyutroni-capturing agent. Amagwiritsidwa ntchito ngati chotsitsa cha nyutroni pakuwongolera zida za nyukiliya, ndikulimbitsa ma radiation.
3. Elemental boron imagwiritsidwa ntchito ngati dopant mu semiconductor industry, pamene boron compounds zimagwira ntchito zofunika monga zopangira kuwala, mankhwala ophera tizilombo ndi otetezera, ndi ma reagents opangira mankhwala.
4. Boron ufa ndi mtundu wa zitsulo zamtengo wapatali zomwe zimakhala ndi gravimetric ndi volumetric calorific values, zomwe zakhala zikugwiritsidwa ntchito kwambiri m'magulu ankhondo monga zopangira zolimba, zophulika zamphamvu kwambiri, ndi pyrotechnics. Ndipo kutentha kwa kutentha kwa ufa wa boron kumachepetsedwa kwambiri chifukwa cha mawonekedwe ake osakhazikika komanso malo akuluakulu enieni;
5. Boron ufa amagwiritsidwa ntchito ngati chigawo cha alloy muzitsulo zapadera kuti apange ma alloys ndikuwongolera makina azitsulo. Itha kugwiritsidwanso ntchito kuvala mawaya a tungsten kapena zodzaza ndi zitsulo kapena zitsulo. Boron nthawi zambiri amagwiritsidwa ntchito mu spcial purpose alloys kuti aumitse zitsulo zina, makamaka ma alloys otentha kwambiri.
6. Boron ufa amagwiritsidwa ntchito ngati deoxidizer mu smelting mkuwa wopanda mpweya. Kuchuluka kwa ufa wa boron kumawonjezeredwa panthawi yachitsulo chosungunula. Kumbali imodzi, imagwiritsidwa ntchito ngati deoxidizer kuteteza chitsulo kuti chisakhale ndi okosijeni pa kutentha kwakukulu. Boron ufa amagwiritsidwa ntchito ngati chowonjezera cha njerwa za magnesia-carbon zomwe zimagwiritsidwa ntchito m'ng'anjo zotentha kwambiri popanga zitsulo;
7. Boron Powders ndi othandizanso pa ntchito iliyonse yomwe malo apamwamba amafunidwa monga kuyeretsa madzi komanso mu mafuta a cell ndi ma solar. Nanoparticles amapanganso madera apamwamba kwambiri.
8. Boron ufa ndi chinthu chofunika kwambiri popanga boron halide yapamwamba kwambiri, ndi zina zopangira boron zopangira; Boron ufa ungagwiritsidwenso ntchito ngati chithandizo chowotcherera; Boron ufa amagwiritsidwa ntchito ngati woyambitsa wa airbags galimoto;
