Khoom Description

Cov khoom no yog ib qho tshwj xeeb ntsuas kub tiv thaiv tivthaiv tsim los rau huab redox, muaj zog acid thiab alkali, thiab ultra- kub lub tshuab nqus tsev ib puag ncig. Raws li kev thaiv sab nraud rau cov thermocouples (tshwj xeeb tshaj yog siab -kev ua tau zoo thermocouple xov hlau xws li tungsten-rhenium thiab platinum-}rhodium), nws lub hom phiaj tseem ceeb yog los tiv thaiv kev yaig thiab lub cev cuam tshuam ntawm cov tshuaj lom neeg sab nraud, cais ib puag ncig impurities, thiab xyuas kom lub sijhawm ntev ntawm kev ntsuas.

UNS R05200 ntshiab tantalum xaiv rau cov khoom no belongs rau high purity smelting qib tantalum, uas txawv ntawm tantalum alloys nrog ntxiv tungsten ntsiab (xws li Ta-2.5W). R05200 qib muaj qhov zoo ntawm chav tsev kub ductility thiab muaj zog chemical corrosion kuj thiab yog tsim nyog raws li lub tes tsho tiv thaiv precision nyob rau hauv hnyav ib puag ncig xws li tshuaj lom neeg kev lag luam thiab semiconductor.

Core Physical and chemical Properties (cov khoom lag luam nyuaj)

Kub txwv thiab ruaj khov: Lub melting point ntawm ntshiab tantalum yog heev siab, xws li ntawm 2996℃mus rau 3017 degree. Qhov no tso cai rau lub raj tiv thaiv kom tswj tau qhov siab ntawm geometric stability nyob rau hauv ultra- qhov kub thiab txias furnaces los yog nyob rau hauv cov kev cuam tshuam ntawm muaj zog kub txaus, zoo tiv thaiv kev ntsuas deviation los yog cov yam ntxwv vau los ntawm cov khoom softening.

Cov tshuaj tsis muaj zog zoo heev: Lub ntsej muag ntawm tantalum tuaj yeem ua rau lub ntsej muag tuab Ta₂O₅ passivation zaj duab xis, muab nws "platinum{0}}zoo li" tshuaj inertness. Nws tuaj yeem tiv taus qhov yaig ntawm cov dej kub npau npau concentrated hydrochloric acid, sulfuric acid, nitric acid thiab aqua regia rau lub sijhawm ntev, thiab nws cov kev tiv thaiv corrosion ntau tshaj li cov khoom siv xws li stainless hlau thiab Hastelloy. Kev saib xyuas tshwj xeeb yuav tsum tau them rau nws cov kev txwv: Ntshiab tantalum tsis tshua muaj siab rau hydrofluoric acid thiab molten alkali ntawm qhov kub thiab txias thiab tsis muaj corrosion kuj.

Thermal thiab Mechanical Properties: Tantalum muaj cov thermal conductivity zoo, uas pab cov thermocouple teb sai sai rau qhov kub thiab txias. Nws qhov siab tshaj plaws yog 16.6 g / cm³, nws lub zog tensile feem ntau ncav cuag Ntau dua lossis sib npaug rau 207 MPa, thiab nws lub zog tawm los Ntau dua lossis sib npaug rau 138 MPa. Nws muaj cov qauv tsim muaj zog thiab tuaj yeem tiv taus lub zog sab hauv lossis sab nraud me ntsis kev puas tsuaj.

Atmosphere dependence: Ntshiab tantalum yog yooj yim oxidized nyob rau hauv huab cua. Nyob rau hauv ib puag ncig huab cua, qhov kev siv tsis tu ncua yog feem ntau txwv rau 400-750 degree; tab sis nyob rau hauv ib puag ncig lub tshuab nqus tsev (<0.013 Pa) or a high-purity inert atmosphere, the use temperature can be greatly increased to 2200–2300°C.

Cov khoom sib txawv qhov zoo

Tsawg roj tso tawm tus nqi: Qib no tau dhau los ntawm lub tshuab nqus tsev electron beam melting thiab cryogenic processing, nrog cov ntsiab lus tsis zoo sab hauv, thiab tom qab kev kho lub tshuab nqus tsev, nws cov roj tso tawm qis heev. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov khoom siv semiconductor MOCVD / PECVD lossis siab -purity thermal teb uas muaj lub tshuab nqus tsev siab heev.

Siab- muaj peev xwm ua tau zoo: Ntxiv rau cov pa ib puag ncig cov raj, precision grooving, drilling, thiab customized qauv ua tau raws li cov duab kos kom ntseeg tau tias tsis muaj micro- tawg lossis kev ntxhov siab yuav tshwm sim nyob rau hauv huab cua kub.

Kev tswj hwm nruj nruj: Ua raws li tus qauv ASTM B521 nruj me ntsis thiab tswj cov ntsiab lus ntawm cov khoom sib txuam xws li oxygen, nitrogen, thiab carbon ntawm cov qib qis heev (xws li O Tsawg dua lossis sib npaug rau 0.015% thiab N Tsawg dua lossis sib npaug li 0.010%) txhawm rau tiv thaiv cov khoom siv los ntawm embrittlement thiab tsis ua haujlwm vim kev sib cais ntawm cov nplej siab.
