Lebennada kubbadda bannaan ee alumina iyo lebennada kubbadda bannaan ee Zirconia
sharaxaad
Lebennada kubbadda bannaan ee alumina waxay ka samaysan yihiin kubbadda bannaan ee alumina iyo budada alumina sida alaabta ceeriin ee ugu weyn, oo ay weheliso binderka kale, ka dib 1750 darajo heerkul sare oo rasaas ah, waxay iska leedahay nooc heerkul aad u sarreeya iyo walxo tamar-badbaadin ah.
Astaamaha
Lebennada kubbadda bannaan ee alumina waxay ka kooban yihiin tiro badan oo porosity xiran, sidaas darteed waxay leedahay awood sare iyo xasilloonida qaab dhismeedka porosity, cufnaanta hoose, caabbinta shoogga kuleylka wanaagsan iyo isbeddel yar oo toosan oo joogto ah, kuleylka kuleylka hooseeya.
Lebennada kubbadda bannaan ee Zirconia oo leh iska caabin heerkul sarreeya, iska caabin kiimikaad daxalka, iska caabinta oksaydhka, iska caabinta xidhashada, ballaadhinta kulaylka weyn.Alaabooyinka kubbadda bannaan ee Zirconia oo ay si buuxda u sameeyeen kubbadda bannaan ee zirconia, oo leh awood heerkul sare oo wanaagsan iyo xasilloonida qaab dhismeedka porosity.
Codsiga
Lebenka kubbadda bannaan ee alumina waxaa inta badan loo adeegsadaa fal-celiyaha gaaska ee warshadaha batroolka, warshadaha madow ee kaarboon, foornada induction ee warshadaha birta, foornada hoos-u-dhaca, foornada siliga molybdenum, foornada ul tungsten, foornada induction, foornada nitrogenation, iyo kuwa kale oo sarreeya. heerkulka, foornooyinka heerkulka sare ee sare.
Lebennada kubbadda bannaan ee Zirconia waxaa loo isticmaalaa qalab heerkul sare ah oo aad u sarreeya sida foornada daboolka qaybo ka mid ah qalabka kuleylka kuleylka, sida foornada heerkulka sare ee inta jeer ee dhexdhexaadka ah, fal-celinta kaarboonka madow, foornada siliga molybdenum, foornada usha tungsten, iwm. Waxqabadka aad u fiican, badbaadada ugu sarreysa heerkulka ka hawlgala waa 2200 ℃, in metallurgical, petrochemical, elektaroonik ah iyo qalabka kale ee kulaylka warshadaha sida xiriir toos ah ololka ee wax dahaarka heerkulka sare, saamaynta isticmaalka wanaagsan.
