Meatotino o carbide silicon recrystallized
Recrystallized silicon carbide (R-SiC) o se mea maualuga-faatinoga ma maaa lona lua i taimane, lea e faia i se vevela maualuga i luga 2000 ℃. E taofiofia le tele o meatotino sili ona lelei o le SiC, e pei o le maualuga o le vevela malosi, malosi faʻafefete, faʻamaʻi faʻamaʻi lelei, faʻamaʻi faʻamaʻi lelei ma isi.
● Mea faʻainisinia sili ona lelei. Recrystallized silicon carbide e maualuga atu le malosi ma le maaa nai lo alava carbon, maualuga aafiaga tetee, e mafai ona faia se faatinoga lelei i siosiomaga vevela vevela, e mafai ona taʻalo se faʻatusatusaga sili atu i tulaga eseese. E le gata i lea, e iai foi le fetuutuunai lelei ma e le faigofie ona faʻaleagaina e ala i le faʻalauteleina ma le punou, lea e faʻaleleia atili ai lona faʻatinoga.
● Tete'e maualuga corrosion. Recrystallized silicon carbide e maualuga le tetee atu i le tele o ala o faasalalauga, e mafai ona taofia le tafia o le tele o ala o faasalalauga corrosive, e mafai ona faatumauina ona meatotino mo se taimi umi, e malosi le pipii, ina ia umi se olaga tautua. E le gata i lea, o loʻo i ai foi le faʻamautu lelei o le vevela, e mafai ona faʻafetaui i se vaega o suiga o le vevela, faʻaleleia lona aoga.
● E le solomuli. Ona o le sintering faagasologa e le solomuli, e leai se popolega o totoe o le a mafua ai le deformation po o le ta'e o le oloa, ma e mafai ona saunia vaega ma foliga faigata ma le sa'o maualuga.
