I-Tungsten ngokwayo ayimnyama, kodwa ibonisa ukubengezela kwentsimbi esiliva-emhlophe. Nangona kunjalo, phantsi kweemeko ezithile, njengaxa usenza i-tungsten carbide, ingabonakala imnyama.
I. Iimpawu zeMbala eziSisiseko zeTungsten
I-Tungsten, i-element kwi-periodic table enenombolo ye-athomu engu-74, sisinyithi esineqondo eliphezulu lokunyibilika. Kwimo yayo yendalo, i-tungsten ibonisa intsimbi esiliva-emhlophe ekhazimlayo, efana nezinye iintsimbi ezininzi. Lo mbala ubangelwa ukubonakaliswa kunye nokusabalalisa ukukhanya ngama-electron amahhala ngaphakathi kwesinyithi. Ngoko ke, xa sibuza, "Ngaba i-tungsten imnyama?" ngokusekelwe kwiimpawu zayo ezisisiseko zomzimba, impendulo ayikho.
II. Iikhompawundi zeTungsten kunye nemibala yazo
Nangona i-tungsten esulungekileyo iyisilivere-mhlophe, iikhompawundi ezithile ze-tungsten zinokubonisa imibala eyahlukileyo. Umzekelo, i-tungsten carbide (WC), i-compound eyenziwe nge-tungsten kunye ne-carbon, ibonakala imnyama. Lo mbala omnyama ungenxa yesakhiwo sayo esithile se-crystal kunye nokuhlelwa kwe-electron. Ngoko ke, kwiimeko ezithile, njengaxa ubhekisela kwi-tungsten carbide, abantu banokukholelwa ngephutha ukuba i-tungsten ngokwayo imnyama.
Izicelo zeTungsten kunye nokuSebenza koMbala
Ngenxa yomgangatho wayo ophezulu wokunyibilika kunye nezinye izinto ezibonakalayo, i-tungsten isetyenziswa kakhulu kwiinkalo ezahlukeneyo, njengokwenziwa kweefilaments kwiibhalbhu zokukhanya. Nangona kunjalo, kwezi zicelo, umbala we-tungsten unokuhluka ngokuxhomekeka kwiqondo lokushisa kunye neemeko zokusingqongileyo. Ngokomzekelo, xa ifudunyezwa ibe yi-incadescence kwiglowubhu yesibane, i-tungsten filament ikhupha ukukhanya okumhlophe okuqaqambileyo kunokuba igcine umbala wayo omhlophe oyisilivere{2}}.
