Rhenium (Re) General Information:
rhenium, lub cim cim: re, atomic tooj 75, nws yog hlau ntawm VIIB pawg. Qhov ceev ntawm rhenium yog 21.04g / cm³, melting point thiab boiling point yog 3186 ° C (5767 ° F, 3459k) thiab 5596 ° C (10105 ° F, 5869k), feem. Rhenium yog cov nyiaj dawb tsis tshua muaj siab melting point hlau. Nws cov ntsiab lus melting thib peb ntawm tag nrho cov ntsiab lus (thawj ob yog tungsten thiab carbon), nws cov ntsiab lus kub yog thawj, thiab nws qhov ntom ntom yog thib plaub (thawj peb yog platinum, iridium thiab osmium). Rhenium hlau yog tawv, hnav-resistant thiab corrosion-resistant. Rhenium ruaj khov nyob rau hauv huab cua thiab vaporizes nrog sulfur ntawm qhov kub thiab txias los ua ke rhenium disulfide, uas tsim halides nrog fluorine, chlorine thiab bromine. Rhenium yog insoluble nyob rau hauv hydrochloric acid, tab sis soluble nyob rau hauv nitric acid thiab kub concentrated sulfuric acid. Rhenium tsis cuam tshuam nrog hydrogen thiab nitrogen, tab sis tuaj yeem nqus tau hydrogen.
