Common Sense ntawm Tantalum

Tantalum - ib tug bluish strategic hlau, hu ua TATALUM nyob rau hauv lus Askiv, muaj ib tug melting point ntawm tshaj 2900 degrees (thib ob xwb rau tungsten thiab rhenium) thiab ib tug Mohs hardness ntawm 6.5 (pob zeb diamond yog 10) thiab ib tug zoo kawg nkaus kuj rau acidity thiab alkalinity (aqua regia). tsis muaj txiaj ntsig rau nws, thiab kub yuav yaj thaum nws kov aqua regia), cov khoom no muab tantalum lub koob npe nrov rau kev ua haujlwm nyuaj, tab sis nws tsis tshua muaj siab dielectric tsis tu ncua (27 yog 4 npaug ntawm aluminium) saum toj no) thiab sintered. sponge xeev thiab lub xeev ruaj khov ua rau cov khoom siv hluav taws xob ua rau cov khoom siv hluav taws xob tiv thaiv kev nyuaj siab thiab yuav tsum tau siv rau cov khoom siv hluav taws xob, thiab thaum kawg muab lawv rau hauv cov khoom siv hluav taws xob tub rog.

Kev lag luam tub rog Asmeskas tau tsim kho heev, thiab nws yog tus xa khoom loj tshaj plaws hauv ntiaj teb. Tsuav koj txaus siab qhib cov khoom siv hluav taws xob ua tub rog, koj tuaj yeem pom tias nws tau them nrog loj thiab me daj tantalum capacitors (interestingly, US tantalum capacitors Lub plhaub yog tag nrho daj, thaum Nyiv thiab lwm tus nyiam siv dub. Cov xim ntawm tantalum capacitor plhaub tsis muaj dab tsi cuam tshuam nrog nws qhov kev ua tau zoo. Lwm cov tantalum capacitor siv nyob rau hauv qhov chaw kub siab yuav tsum tau haus luam yeeb siab tshaj 150 degrees, yog li lub plhaub daj tuaj yeem haus luam yeeb dub, yog li tsuas yog xim dub).
