Ib qho kev sib tw hlau tsim cov tshuaj lom neeg cov nyiaj (ag), nws muaj xim dawb dawb thiab muaj zog nws yog xim hlau. Nws yog tshuaj tsis ruaj khov, tab sis nws yooj yim sib xyaw nrog cov leej faj los ua nyiaj sulfide, uas tuaj yeem ua rau cov nyiaj ntawm cov nyiaj kom tsaus thiab discolor. Nws tus txheeb ze ceev yog 10.49. Nws lub hardness yog 2.5-3. Nws lub taw tes melting yog 961.93 degree. Nws yog cov ductas (thib ob tsuas yog rau kub) thiab tus neeg coj ua zoo ntawm tshav kub thiab hluav taws xob. Nyiaj yog ib txwm siv hlau nyob rau hauv cov hniav nyiaj hniav kub, tab sis vim nws muag dhau lawm, nws yog feem ntau deev nrog lwm cov ntsiab lus (zinc, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab npib tooj liab, thiab ob leeg). Cov qauv nyiaj muaj cov ntsiab lus ntawm 92.5%. Hauv cov sij hawm niaj hnub no, vim nws nyiam ua kom tsaus nti thiab poob nws tus nqi qis dua kub thiab platinum, nyiaj feem ntau siv hauv cov hniav nyiaj hniav kub pheej yig. Nyiaj kuj muaj ntau cov kev siv muaj kev lag luam, xws li nws cov kev coj ua zoo hauv cov hluav taws xob thiab cov twj paj nruag rau ntau yam kev ntsuas.
925 sterling nyiaj yog tus txheej txheem thoob ntiaj teb rau nyiaj cov hniav nyiaj hniav kub. [Nco tseg: Cov hauv qab no tshwm sim ua ib qho tawg,] Nyiaj-kub feem ntau yog feem ntau stewing "(" s "lossis" s "lossis" s "lossis" s "lossis" s "lossis" s "lossis" s "lossis" s "lossis" sterling "). Sterling nyiaj yog thwj tim S925. Nplua nyiaj yog stamped s990. Txawm li cas los xij, ntau lub teb chaws tsis muaj stamp cov hniav nyiaj hniav kub nrog cov cim no.
Lwm Cov Nyiaj Txiag Dawb:
Platinum, cim PT (PT850 / 900/950/990/999).
Platinum: dawb kub, feem ntau ua ntawm kub.
Nyiaj: Tshuaj lom zem AG (los ntawm Latin Argentum, Art-} European paus sawv cev grey thiab shimmer). Atomic tus naj npawb 47, nws yog cov hlau hloov. Cov nyiaj tau tshwm sim hauv cov nyiaj pub dawb hauv nws daim ntawv dawb hauv xwm, feem ntau raws li nyiaj compound ores. Nyiaj yog Chemically ruaj khov, muaj cov reactivity tsawg, thiab kim. Txawm li cas los xij, nws muaj cov thermal thiab hluav taws xob zoo heev, tsis yooj yim corroded los ntawm tshuaj lom neeg, thiab yog mos thiab ductile.
