Ib boride yog ib qho sib xyaw ntawm boron thiab cov khoom siv hluav taws xob tsawg dua, piv txwv li silicon boride. Cov borides yog ib pawg loj heev ntawm cov tebchaw uas feem ntau yog melting siab thiab yog covalent ntau tshaj ionic nyob rau hauv cov xwm. Qee qhov borides nthuav tawm lub cev muaj txiaj ntsig zoo heev.
borides rau dab tsi?
Kev siv cov borides thiab lwm cov tebchaw feem ntau yog raws li lawv cov hardness, tshuaj inertness, thiab sib nqus thiab hluav taws xob khoom Ob peb piv txwv yuav tau hais. B4C thiab cubic BN yog siv los ua abrasives, B4C thiab hexaborides ua txheej txheej, thiab CaB6ua tus neeg saib xyuas deoxidation hauv qee cov txheej txheem metallurgical.
Yuav ua li cas borides?
Borides yog tsim los ntawm melting lossis sintering hlau nrog boron. Nyob ntawm qhov sib piv ntawm cov hlau-boron, qhov tshwm sim tuaj yeem nplua nuj nyob hauv boron. Electropositive hlau xws li alkali hlau tsim cov tebchaw uas nplua nuj nyob rau hauv boron, piv txwv li MB2.
borane yog dab tsi?
borane, ib yam ntawm homologous series ntawm inorganic compounds ntawm boron thiab hydrogen los yog lawv cov derivatives.
Puas yog boron yog hlau?
Boron, lub teeb tshaj plaws ntawm cov ntsiab lus no, yog a metalloid. Aluminium, gallium, indium, thiab thallium yog silvery dawb hlau.
