MgAl2O4 Substrate txhais
MgAl2O4 substrate yog hais txog ib hom tshwj xeeb ntawm substrate ua los ntawm compound magnesium aluminate (MgAl2O4).Nws yog cov khoom siv ceramic nrog ntau yam khoom tsim nyog rau ntau yam kev siv.
MgAl2O4, tseem hu ua spinel, yog cov khoom siv pob tshab nrog cov thermal stability, tshuaj tiv thaiv thiab txhua yam muaj zog.Cov khoom no ua rau nws tsim nyog rau kev siv los ua lub substrate nyob rau hauv ntau yam kev lag luam, xws li electronics, optics thiab aerospace.
Hauv kev lag luam hluav taws xob, MgAl2O4 substrates tuaj yeem siv los ua lub platform rau kev loj hlob ntawm cov yeeb yaj kiab nyias thiab cov txheej txheem epitaxial ntawm semiconductors lossis lwm yam khoom siv hluav taws xob.Qhov no tuaj yeem ua rau kev tsim cov khoom siv hluav taws xob xws li transistors, kev sib koom ua ke thiab cov sensors.
Hauv kev kho qhov muag, MgAl2O4 substrates tuaj yeem siv rau kev tso tawm ntawm cov yeeb yaj kiab nyias los txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov khoom siv kho qhov muag xws li lo ntsiab muag, cov ntxaij lim dej thiab iav.Lub substrate lub pob tshab thoob plaws ntau yam ntawm wavelengths ua rau nws tshwj xeeb tshaj yog haum rau cov kev siv nyob rau hauv lub ultraviolet (UV), pom, thiab ze-infrared (NIR) cheeb tsam.
Hauv kev lag luam aerospace, MgAl2O4 substrates yog siv rau lawv cov thermal conductivity thiab thermal shock resistance.Lawv yog siv los ua cov khoom siv hauv tsev rau cov khoom siv hluav taws xob, kev tiv thaiv thermal thiab cov khoom siv.
Zuag qhia tag nrho, MgAl2O4 substrates muaj kev sib xyaw ua ke ntawm cov khoom siv kho qhov muag, thermal, thiab cov khoom siv kho qhov muag uas ua rau lawv muaj txiaj ntsig hauv ntau yam kev siv, suav nrog cov khoom siv hluav taws xob, optics, thiab kev lag luam aerospace.
