Hafnium Boride hmoov

Hafnium Boride piav qhia

Hafnium boride (los yog hafnium diboride) yog ib qho tshwj xeeb kub-kub ceramic khoom nrog zoo thermal thiab hluav taws xob conductivity. Nws yog ib qho txawv txav ceramic, muaj cov thermal thiab hluav taws xob conductivity.

Hafnium boride yog lub teeb grey, nws yog xim hlau-zoo li cov khoom. Lub oxidation tsis kam ntawm hafnium boride yog nyob ntawm qhov kub thiab txias. Ntawm qhov kub ntawm 1500 degree thiab 1 atm ntawm lub siab, tiv thaiv oxide nplai ntawm cov ntaub ntawv hafnia. Thaum kub nce siab tshaj 1600 degree thiab qhov siab poob qis dua 1 atm, oxidation tsis kam ntawm HfB2 tau txo qis heev.

Hafnium boride hmoov muaj peev xwm siv tau rau hauv cov tsheb thauj mus los xws li ICBM cov khoom siv hluav taws xob los yog cov aerodynamic ua-ntug, vim nws lub zog thiab thermal zog. Tsis zoo li cov khoom siv polymer thiab cov khoom sib xyaw, HfB2 tuaj yeem tsim rau hauv cov duab aerodynamic uas yuav tsis ablate thaum rov nkag.

Hafnium boride tseem raug tshawb xyuas raws li cov khoom siv tshiab tau rau cov khoom siv hluav taws xob nuclear. Nws kuj tseem raug tshawb xyuas raws li microchip diffusion barrier. Yog tias ua kom raug, qhov barrier tuaj yeem tsawg dua 7 nm tuab.
