Borides yog cov tebchaw uas muaj boron thiab tsawg electronegative ntsiab. Feem ntau cov borides yog cov hlau sib txuas uas nws cov qauv dav dav yog MnBm, qhov twg boron raug nqi tsis zoo. Borides raug tsim los ntawm melting lossis sintering hlau nrog boron Nyob ntawm qhov piv ntawm cov hlau-boron, qhov tshwm sim tuaj yeem nplua nuj hauv boron.

boride yog dab tsi?

Borides yog txhua yam nyuaj, cov ntaub ntawv siab melting point nrog hlau zoo li conductivity. Lawv tuaj yeem ua tau los ntawm kev sib xyaw ua ke ntawm cov ntsiab lus ntawm qhov kub thiab txias, feem ntau, los ntawm kev txo qhov kub ntawm ib qho sib tov ntawm cov hlau oxide thiab boron oxide siv cov pa roj carbon lossis txhuas

Puas yog boride?

A boride is a compound between boron and a less electronegative element , piv txwv li silicon boride (SiB3 and SiB 6). Cov borides yog ib pawg loj heev ntawm cov tebchaw uas feem ntau siab melting thiab yog covalent ntau tshaj ionic nyob rau hauv cov xwm.

txheej txheem Boronizing yog dab tsi?

Boriding, tseem hu ua boronizing, yog txheej txheem uas boron ntxiv rau cov hlau lossis hlau Nws yog hom tawv tawv. Nyob rau hauv cov txheej txheem no boron atoms yog diffused rau saum npoo ntawm ib tug hlau tivthaiv. … Feem ntau borided steel nto yuav muaj hlau boride txheej hardnesses li ntawm 1200-1600 HV.

Mg3B2 yog dab tsi?

Magnesium Boride Mg3B2 Molecular Luj - EndMemo.
