Kodi Rare Metal ndi chiyani?
Kwa zaka zingapo zapitazi, timakonda kumva za "vuto losowa kwambiri lachitsulo" kapena "vuto lachitsulo". Mawu akuti, "zitsulo zosawerengeka", sizomwe zimafotokozedwa m'maphunziro, ndipo palibe mgwirizano pa zomwe zimakhudza. Posachedwapa, mawuwa amagwiritsidwa ntchito kutanthauza zinthu zazitsulo za 47 zomwe zikuwonetsedwa mu Chithunzi 1, malinga ndi tanthawuzo lomwe limayikidwa bwino. Nthaŵi zina, maelementi 17 a dziko lapansi osowa kwambiri amawaona kukhala amtundu umodzi, ndipo chiwonkhetso chonse amaŵerengedwa kukhala 31. Pali zinthu zonse 89 zimene zilipo m’chilengedwe, motero tinganene kuti zoposa theka la zinthuzo ndi zitsulo zosoŵa. .
Zinthu monga titaniyamu, manganese, chromium, zomwe zimapezeka mochulukira m'nthaka ya dziko lapansi, zimawonedwanso ngati zitsulo zosowa. Izi zili choncho chifukwa manganese ndi chromium akhala zinthu zofunika kwambiri kwa mafakitale kuyambira masiku ake oyambirira, zomwe zimagwiritsidwa ntchito ngati zowonjezera kuti ziwonjezere mphamvu zachitsulo. Titaniyamu imaonedwa kuti ndi "yosowa" chifukwa ndi chitsulo chovuta kupanga monga teknoloji yapamwamba imafunikira pakuyenga miyala yambiri ya titanium oxide. Kumbali ina, kuchokera ku zochitika zakale, golidi ndi siliva, zomwe zakhalapo kuyambira kale, sizimatchedwa zitsulo zosawerengeka.Kuchokera m'mbiri yakale, golidi ndi siliva, zomwe zakhalapo kuyambira kale, sizimatchedwa zitsulo zosawerengeka. .
