(3) Hluav taws xob conductivity: Txawm hais tias qhov hluav taws xob conductivity ntawm tungsten tsis zoo li tooj liab thiab nyiaj, nws tseem tuav tau zoo hluav taws xob conductivity ntawm qhov kub thiab txias, uas tso cai rau tungsten lub hom phiaj kom ua tau zoo tam sim no hauv cov khoom siv hluav taws xob ntawm qhov kub thiab txias, xws li X-ray tubes.
(4) Thermal conductivity: Tungsten muaj cov thermal conductivity siab thiab tuaj yeem hloov cov cua sov kom zoo thiab txo qhov kev puas tsuaj los ntawm cov cua sov. Nyob rau hauv cov txheej txheem tsim khoom semiconductor, nws cov thermal conductivity zoo pab tswj qhov kub thiab txias thaum lub sijhawm kev loj hlob ntawm zaj duab xis, txhim kho kev tsim khoom thiab cov khoom zoo.
(5) Corrosion kuj: Tungsten muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus qhov yaig ntawm feem ntau cov kua qaub thiab alkalis. Cov yam ntxwv no ua rau tungsten lub hom phiaj tsis tshua muaj siab thiab txhim khu kev qha hauv kev siv tshuaj lom neeg thiab kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive.
(6) Hnav tsis kam: Tungsten muaj qhov tawv tawv heev thiab nyob hauv qab pob zeb diamond, yog li nws qhov chaw muaj zog hnav tsis kam. Hauv cov ntawv thov uas xav tau kev hnav tsis kam, xws li hauv qee yam khoom siv thiab cov khoom siv, tungsten lub hom phiaj tuaj yeem ua kom ntev lub neej ntawm cov khoom.
2. Daim ntawv thov zoo ntawm Tungsten Lub Hom Phiaj hauv kev tshawb fawb txog kev kho mob
Daim ntaub ntawv: Cov cuab yeej siv kho mob (xws li CT scanners, X-ray tshuab), kev kuaj xyuas qhov tsis zoo (xws li kev kuaj tsis muaj kev puas tsuaj), thiab cov khoom siv hluav taws xob tiv thaiv hluav taws xob.
Tungsten Cov Hom Phiaj yog siv los ua cov khoom siv anode ntawm X-ray raj, thiab lawv cov ntsiab lus siab melting thiab thermal stability yog siv los sib tsoo nrog electrons ntawm high voltage ntawm kev kub ceev los tsim X-rays. Cov X-rays no yog siv los nkag mus rau tib neeg lub cev lossis cov ntaub ntawv los tsim cov duab rau kev kuaj mob lossis kuaj pom cov qauv sab hauv ntawm cov khoom. Nws qhov siab melting point thiab thermal stability ua rau X-ray tiam muaj txiaj ntsig zoo dua thaum muab cov duab pom tseeb dua. Daim ntawv thov no tsis tsuas yog txhim kho qhov zoo ntawm cov duab kho mob, tso cai rau cov kws kho mob kom kuaj xyuas cov kab mob kom raug, tab sis kuj tseem pab txo cov kab hluav taws xob tau txais los ntawm cov neeg mob, txhim kho kev nyab xeeb thiab kev ua tau zoo.
Siv cov khoom muaj zog ntawm tungsten, Tungsten Targets tau siv dav hauv kev kho mob hluav taws xob. Lawv tau siv los ua cov khoom siv tiv thaiv los tsim X-ray tiv thaiv thaiv, ntim thiab lwm yam khoom siv tiv thaiv, tiv thaiv hluav taws xob hluav taws xob zoo los ntawm kev ua phem rau cov neeg ua haujlwm kho mob thiab cov neeg mob, thiab txhim kho kev nyab xeeb ntawm kev kho mob hauv xov tooj cua. kev nyab xeeb.
3. Tungsten Targets txhim kho kev tsim khoom hauv kev lag luam semiconductor
Raws li cov khoom siv hluav taws xob txhim kho mus rau qhov me me thiab kev ua haujlwm siab dua, kev tsim khoom semiconductor tab tom ntsib qhov kev xav tau siab heev thiab purity. Hauv kev tsim hluav taws xob sib xyaw ua ke, tungsten lub hom phiaj yog siv rau lub cev vapor deposition los tsim cov yeeb yaj kiab hlau zoo. Kev siv cov phiaj xwm tungsten txhim kho cov kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zoo. Nws tsis tsuas yog txhawb nqa kev nce qib sai ntawm semiconductor thev naus laus zis thiab txhawb kev tsim kho thev naus laus zis hauv smartphones, khoos phis tawj thiab lwm yam khoom siv hluav taws xob, tab sis kuj txhim kho cov khoom lag luam thiab kev ua haujlwm zoo hauv microelectronics manufacturing process. Kev ntseeg tau txhawb txoj kev loj hlob sai thiab miniaturization ntawm semiconductor technology.
