Sintered Mullite

Mullite ndi gulu la binary lomwe limakhalapo mokhazikika pansi pazambiri zamabinala a Al2O3-SiO2. The mankhwala chilinganizo ndi 3Al2O3-2SiO2, ndi zikuchokera chiphunzitso ndi: Al2O3 71.8%, SiO2 28.2%. Poyerekeza ndi mullite wachilengedwe *, mullite yomwe imagwiritsidwa ntchito nthawi zambiri imapangidwa mwaluso, kuphatikiza sintered mullite ndi kusakaniza mullite.

Synthetic mullite ndi zida zapamwamba kwambiri zokanira. Ili ndi mawonekedwe akukula kwa yunifolomu, kukhazikika kwamphamvu kwamafuta, malo ochepetsera katundu wambiri, kamtengo kakang’ono ka kutentha, kuuma kwakukulu, komanso kukana kwa dzimbiri kwamankhwala.

Njira yopanga ndi njira ya sintered mullite:

Sintered mullite imapangidwa ndi bauxite yachilengedwe yapamwamba kwambiri ngati yaiwisi, ndipo imatenthedwa mu uvuni wotentha kwambiri wopitilira 1750 ℃ ​​kudzera munjira yosankha komanso ma homogenization ambiri.

Mawonekedwe ndi magwiridwe antchito a sintered mullite:

Sintered mullite imakhala ndi mawonekedwe apamwamba, kachulukidwe kachulukidwe kake, kukhazikika kwamphamvu kwamafuta, kutsika kochepa kwambiri kwa kutentha komanso kukana kwa dzimbiri kwamankhwala, ndipo mtundu wake ndi wokhazikika. Nthawi yomweyo, sintered mullite ndikupanga mawonekedwe osiyanasiyana komanso zosatsimikizika. Zopangira zabwino zopangira zinthu zokanira, zopanda kanthu zaukhondo, kuponyera mwatsatanetsatane ndi zinthu zina.

Zolemba zakuthupi ndi zamankhwala za sintered mullite:
