tantalum hlau pas nrig
Nws cov ntsiab lus melting yog siab li 2996 degree, qeb thib peb tom qab tungsten thiab rhenium. Tantalum yog ductile thiab tuaj yeem kos rau hauv filaments lossis ua rau nyias nyias. Nws cov coefficient ntawm thermal expansion yog me me, nthuav tsuas yog 6.6 qhov chaw ntawm ib lab rau txhua qib Celsius nce. Tsis tas li ntawd, nws qhov toughness yog qhov muaj zog heev, txawm tias zoo dua li tooj liab.
ua metal rod
Tantalum kuj muaj cov tshuaj lom neeg zoo heev thiab tsis tshua muaj corrosion kuj. Tsis muaj teeb meem nyob rau hauv txias los yog kub kub, nws tsis muaj tshuaj tiv thaiv rau hydrochloric acid, concentrated nitric acid thiab "aqua regia". Thaum tantalum soaked nyob rau hauv sulfuric acid ntawm 200 degree rau ib xyoos, cov txheej saum npoo tsuas yog puas los ntawm 0.006 hli. Tungsten phaj, molybdenum phaj, tungsten pas nrig, molybdenum pas nrig, tungsten raj, molybdenum raj, tungsten crucible, molybdenum crucible. Kev sim tau ua pov thawj tias tantalum tsis muaj kev cuam tshuam rau cov tshuaj alkali, chlorine gas, dej bromine, dilute sulfuric acid thiab ntau lwm yam tshuaj nyob rau hauv ib txwm muaj. , tsuas yog reacts nyob rau hauv qhov kev txiav txim ntawm hydrofluoric acid thiab kub concentrated sulfuric acid. Cov xwm txheej zoo li no kuj tsis tshua muaj nyob hauv cov hlau.
daim ntawv ntshiab
Cov khoom ntawm tantalum ua rau nws daim ntawv thov teb dav heev. Hauv cov cuab yeej siv rau kev npaj ntau yam inorganic acids, tantalum tuaj yeem siv los hloov cov hlau tsis muaj steel, thiab nws lub neej kev pabcuam tuaj yeem txuas ntxiv rau ntau lub sijhawm piv rau stainless hlau. Tsis tas li ntawd, hauv kev lag luam tshuaj, hluav taws xob, hluav taws xob thiab lwm yam lag luam, tantalum tuaj yeem hloov cov dej num uas tau ua los ntawm cov hlau zoo heev platinum, txo tus nqi zoo heev.
