Tungsten Lub Hom Phiaj

tungsten lub hom phiaj cov khoom, cov khoom siv tshuaj cim ntawm tungsten yog W, atomic tooj yog 74, tus txheeb ze atomic loj yog 183.85, lub vojvoog atomic yog 137 picometers, qhov ceev yog 19.35 grams ib cubic centimeter, belongs rau VIB pab pawg neeg thib rau. lub sij hawm (lub sij hawm thib ob ntev tshaj plaws) nyob rau hauv lub sij hawm ntawm lub ntsiab lus. Lub vojvoog ionic ntawm tungsten yog 0.68 × 10-10 m. Vim yog lub vojvoog me me ntawm W6 ntxiv ion, tus nqi hluav taws xob siab thiab muaj zog polarization muaj peev xwm, tungsten feem ntau yog nyob rau hauv daim ntawv ntawm complex anion [WO4]2-, uas ua ke nrog Fe2 ntxiv, Mn2 ntxiv, Ca2 ntxiv thiab lwm yam cations. nyob rau hauv kev daws rau tsim wolframite los yog scheelite precipitates. Tom qab smelting, tungsten yog ib tug silvery-dawb lustrous hlau nrog ib tug heev melting point, zoo hardness, tsawg vapor siab, me me evaporation tus nqi, thiab tshuaj stability. Tungsten tuaj yeem siv rau hauv kev tsim cov phom, foob pob ua ntxaij propulsion nozzles, txiav hlau hniav, xyaum, superhard dies, hlau drawing tuag, thiab lwm yam. Nws muaj ntau yam kev siv. Qhov tseem ceeb tshaj plaws ntawm lub xeev cov txheej txheem yog hlau alloy, ntau yam forged qhov chaw ntawm ntshiab tungsten yog siv nyob rau hauv zus tau tej cov hluav taws xob raj, xov tooj cua electronics thiab X-ray technology, thiab cov tebchaw yog tsuas yog siv nyob rau hauv zus tau tej cov hom lacquers thiab pigments. , inks, electroplating, thiab lwm yam. Nws kuj yog siv los ua catalyst, thiab lwm yam.

Peb tsim cov purity siab purity sputtering lub hom phiaj, uas nws cov txiaj ntsig tseem ceeb tshaj plaws yog kom tau txais cov yeeb yaj kiab nrog cov hluav taws xob zoo heev thiab kev ua kom tsawg tsawg thaum lub sij hawm lub cev vapor deposition. Cov lus hauv qab no qhia tau tias daim ntawv pov thawj ntawm kev tsom xam ntawm 3N5 siab purity tungsten sputtering lub hom phiaj. Kev txheeb xyuas cov txheej txheem siv: 1, kev txheeb xyuas cov hlau hlau siv ICP-OES; 2, kev tsom xam cov roj av siv LECO.
