Osmium (Os) General Information:
Osmium, lub cim cim Os, atomic naj npawb 76, txheeb ze atomic mass 190.23, belongs rau platinum pawg hlau hnyav thiab yog cov hlau densest paub. Nws qhov ceev nce mus txog 22.48g / cm3, nws cov ntsiab lus melting yog 3045 ° C, thiab nws qhov kub siab tshaj 5027 ° C. Hexagonal tuab lattice. Grey-xiav hlau, tawv thiab nkig. Thaum pounded nyob rau hauv ib tug hlau mortar, nws yuav yooj yim tig mus ua hmoov. Osmium hmoov yog xiav-dub, thiab osmium hlau hmoov tuaj yeem ignite spontaneously.

Osmium tuaj yeem siv los ua cov catalyst hauv kev lag luam. Yog tias koj sib tov me ntsis osmium rau hauv platinum, koj tuaj yeem ua ib qho nyuaj thiab ntse osmium-platinum alloy scalpel. Osmium thiab ib qho nyiaj ntawm iridium tuaj yeem siv los ua ib qho osmium-iridium alloy. Piv txwv li, me me nyiaj-dawb dot ntawm lub ntsis ntawm ib co high-end kub cwjmem yog ib qho osmium-iridium alloy. Lub osmium-iridium alloy yog ib qho nyuaj thiab hnav-tiv taus thiab tuaj yeem siv los ua cov kabmob rau cov moos thiab cov cuab yeej tseem ceeb. , muaj lub neej ua haujlwm ntev.
