Nano alumina muab cov khoom kub kub lub zog thiab hardness, thiab yuav tsis txo cov conductivity ntawm cov alloy, thiaj li hais tias cov khoom muaj ib tug zoo tag nrho-round kev ua tau zoo, tshwj xeeb tshaj yog 1000 ℃ kub kho tsis tuaj yeem hloov nws cov kev ua tau zoo, txawv teb chaws hu ua "Super Tooj".

Vim lub dispersion ntawm txhuas oxide nyob rau hauv lub tooj liab matrix nyob rau hauv txoj kab uas hla ntawm tsuas yog ob peb nanometers, thiab cov feem pua ​​ntawm cov ntsiab lus yog heev me me, yog li qhov dispersion ntawm tooj liab nrog ntshiab tooj liab thiab lwm yam tooj liab alloys zoo ib yam li cov hluav taws xob thiab thermal conductivity.
