Ntau cov hlau thiab lawv cov tebchaw yuav tsum tau ua rau hauv cov yeeb yaj kiab nyias ua ntej lawv tuaj yeem siv rau hauv cov khoom siv xws li electronics, displays, fuel cells, or catalytic applications. Txawm li cas los xij, "resistant" hlau, suav nrog cov ntsiab lus xws li platinum, iridium, ruthenium, thiab tungsten, yog qhov nyuaj rau tig mus rau hauv cov yeeb yaj kiab nyias vim tias qhov kub thiab txias (feem ntau tshaj 2,000 degrees Celsius) yuav tsum tau evaporate lawv.
Feem ntau, cov kws tshawb fawb tsim cov yeeb yaj kiab hlau no siv txoj hauv kev xws li sputtering thiab electron beam evaporation. Cov tom kawg yog melting thiab evaporation ntawm cov hlau nyob rau hauv high kub thiab tsim ib tug nyias zaj duab xis nyob rau hauv lub phaj. Txawm li cas los xij, hom kev cai no yog kim, siv ntau lub zog, thiab tuaj yeem ua rau tsis zoo vim yog siv hluav taws xob ntau.
Cov hlau no yog siv los ua cov khoom suav tsis tau, los ntawm cov khoom siv hluav taws xob rau cov ntawv siv computer los tso saib cov thev naus laus zis. Platinum, piv txwv li, kuj yog ib qho tseem ceeb ntawm lub zog hloov pauv thiab khaws cia catalyst thiab raug txiav txim siab siv rau hauv cov khoom siv spintronics.
