yttria yokhazikika ya zirconia powder
Mafotokozedwe Akatundu
Yttrium stabilized zirconia, yomwe imadziwikanso kuti YSZ, ndi chinthu chatsopano chomwe chili ndi zinthu zabwino kwambiri.
Mapangidwe a kristalo a YSZ amapangidwa ndi zirconia ndi yttrium oxide, momwe zirconia crystal structure ndi monoclinic crystal system ndi yttrium oxide crystal structure ndi cubic crystal system.Mapangidwe apadera a kristalowa amathandizira YSZ kukhala ndi zinthu zabwino kwambiri monga malo osungunuka kwambiri, kuuma kwakukulu, kukana kwambiri komanso kutsika kwapakati pakukulitsa kwamafuta.
YSZ imawonetsa kukana kwamphamvu kwamafuta pa kutentha kwakukulu, komwe kumachitika chifukwa cha kukhazikika kwamafuta amtundu wake wa kristalo.
YSZ ili ndi ntchito zambiri m'madera ambiri, monga mphamvu, chitetezo cha chilengedwe, ndege, magalimoto, zamagetsi, ndi zina zotero.Pachitetezo cha chilengedwe, YSZ ingagwiritsidwe ntchito kuchotsa mpweya woipa mumlengalenga ndi zinthu zovulaza m'madzi onyansa.M'magawo apamlengalenga ndi magalimoto, YSZ ingagwiritsidwe ntchito kupanga zida za ceramic zogwira ntchito kwambiri komanso zida zolimbana ndi kutentha kwambiri.

Kugwiritsa ntchito
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.
