spherical high purity niobium carbide ufa
Mafotokozedwe Akatundu
Niobium carbide ufandi mtundu wazinthu zopanda zitsulo zomwe zimakhala ndi mtengo wofunikira.Amapangidwa makamaka ndi niobium ndi kaboni, ndipo ali ndi zinthu zabwino kwambiri zakuthupi, zamankhwala komanso zamakina.Njira zazikulu zopangira ufa wa niobium carbide zimaphatikizapo njira yochepetsera carbothermal ndi njira yosungunuka yamchere ya electrolysis.Pakati pawo, njira yochepetsera carbothermal ndiyo yomwe imagwiritsidwa ntchito kwambiri, mfundo ndiyo kuchepetsa niobium oxide kapena niobium alloy ndi carbon pa kutentha kwakukulu kuti mupeze niobium carbide powder.Njira yosungunula mchere wa electrolysis ndi kugwiritsa ntchito kusakaniza kwa mchere wa niobium ndi mchere wa carbon kuti electrolysis pa kutentha kwakukulu, kotero kuti niobium ion imachepetsedwa kukhala niobium carbide pa cathode.
Niobium carbide ufa chimagwiritsidwa ntchito m'madera ambiri, monga zamagetsi, zakuthambo, makina, zitsulo ndi zina zotero.Pazinthu zamagetsi, niobium carbide ingagwiritsidwe ntchito popanga zida zopangira kutentha kwambiri komanso zida zamagetsi chifukwa cha kutentha kwambiri komanso kukana kwa radiation.Pankhani yazamlengalenga, niobium carbide alloy ili ndi zabwino zamphamvu kwambiri, kulemera kopepuka komanso kukana dzimbiri, ndipo ndizofunikira kwambiri popanga injini za ndege ndi zida za roketi.

Njira yoyendetsera bwino
Huarui ali ndi dongosolo lokhazikika loyang'anira.Timayesa zinthu zathu poyamba tikamaliza kupanga, ndipo timayesanso tisanaperekedwe, ngakhale zitsanzo.Ndipo ngati mukufuna, tikufuna kuvomereza gulu lachitatu kuti tiyese.Zachidziwikire ngati mukufuna, titha kukupatsani zitsanzo kuti muyese.
Zogulitsa zathu zimatsimikiziridwa ndi Sichuan Metallurgical Institute ndi Guangzhou Institute of Metal Research.Kugwirizana kwanthawi yayitali ndi iwo kumatha kupulumutsa nthawi yambiri yoyesera kwa makasitomala.
