Leben badan

Lebenka mullite-ka ah waxa uu qaataa corundum saxan la soo dhoofiyo iyo corundum isku dhafan oo nadiif ah oo sarreeya sida alaabta ceeriin ee ugu muhiimsan, oo waxay qabataa tignoolajiyada kordhinta budada ultrafine ee horumarsan. Ka dib marka la isku daro, la qalajiyo oo la sameeyo, waxaa lagu shideeyaa foorno heerkul sare leh.
Al2O3 waxa ku jira: 60-75%
Cufnaanta weyn: 2.55g /cm3
Sharaxaada
Lebenka Mullite waa nooc ka mid ah refractories High-aluminium ah oo tixgeliya mullite (Al2O3 • SiO2) sida wajiga ugu weyn ee crystal. Celcelis ahaan waxa ku jira aluminiumku waa inta u dhaxaysa 65% iyo 75%. Marka lagu daro halabuurka macdanta mullite, oo ka kooban alumina hoose ayaa sidoo kale ku jira qadar yar oo galaas ah iyo cristobalite; alumina sare oo ka kooban qadar yar oo corundum ah. Refractory sare ilaa 1790 ° C. Ku dheji heerkulka bilawga jilcinta 1600 ~ 1700 °C. Heerkulka qolka xoogga cadaadiska 70 ~ 260MPa. Iska caabbinta shoogga kulaylka wanaagsan.
