Hafnium tetrachloride, kuj hu uaHafnium (IV) chloride or HfCl4, yog qhov sib xyaw nrog CAS tus lej13499-05-3. Nws yog tus cwj pwm los ntawm purity siab, feem ntau 99.9% rau 99.99%, thiab cov ntsiab lus qis zirconium, ≤0.1%. Cov xim ntawm hafnium tetrachloride hais feem ntau yog dawb lossis dawb, nrog qhov ntom ntawm 3.89 g / cubic centimeter thiab melting point ntawm 432 ° C. Qhov tseem ceeb, nws tawg hauv dej, qhia tias nws cuam tshuam nrog dej.
Hafnium tetrachloridetuaj yeem siv los ua tus thawj coj hauv kev tsim khoom ntawm ultra-siab kub ceramics. Paub txog lawv cov thermal stability zoo, cov ceramics no tau siv ntau yam kev siv kub, xws li thermal tiv thaiv systems hauv kev lag luam aerospace thiab kev tsim cov cuab yeej txiav thiab crucibles. Qhov sib xyaw ua ke muaj peev xwm tiv taus qhov kub thiab txias ua rau nws yog ib qho tseem ceeb hauv kev tsim cov khoom siv rau cov thev naus laus zis thiab kev siv hauv kev lag luam.
Ntxiv mus,Hafnium tetrachloride hmoovplays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm high-power LEDs. Nws yog siv rau hauv kev tsim cov phosphorus, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm LEDs. Phosphors yog cov ntaub ntawv uas tawm lub teeb thaum raug hluav taws xob thiab yog ib qho tseem ceeb rau LED kev ua tau zoo los ntawm kev hloov lub teeb xiav rau hauv lwm cov xim, yog li txhim kho tag nrho cov efficiency thiab xim zoo ntawm lub teeb pom kev zoo.
High-purityHafnium tetrachloride hmoovtuaj yeem hloov kho kom txo cov ntsiab lus zirconium rau 200ppm, kom ntseeg tau tias nws tsim nyog rau kev thov cov ntawv thov uas impurities tuaj yeem cuam tshuam rau cov khoom kawg. Qib no ntawm purity yog qhov tseem ceeb rau kev ua tiav kev sib txuas ntawm cov khoom siv siab heev, qhov kev tswj xyuas cov tshuaj muaj pes tsawg leeg yog qhov tseem ceeb.
Hauv cov ntsiab lus,Hafnium tetrachloride hmoov, nrog nws cov purity zoo heev thiab cov khoom tshwj xeeb, tau dhau los ua qhov tseem ceeb tshaj plaws rau kev tsim cov khoom siv hluav taws xob ultra-siab kub thiab ua lub luag haujlwm tseem ceeb hauv kev nce qib ntawm high-power LED technology. Nws versatility thiab reactivity ua rau nws yog ib qho tseem ceeb nyob rau hauv txoj kev loj hlob ntawm cov ntaub ntawv rau cutting-edge industrial thiab technical applications.
