Ceramization ea holim'a metsi - ho fafatsa ka plasma le ho iketsetsa mocheso o phahameng
Ho fafatsa ka plasma ho hlahisa arc ea DC pakeng tsa cathode le anode. Arc e etsa hore khase e sebetsang e be plasma e nang le mocheso o phahameng. Lelakabe la plasma le etsoa ho qhibilihisa phofo ho etsa marotholi. Molapo o phahameng oa khase o etsa atomization ea marotholi ebe o a ntša ho substrate. Bokaholimo bo etsa lesela. Molemo oa ho fafatsa ka plasma ke hore mocheso oa ho fafatsa o phahame haholo, mocheso o bohareng o ka fihla ho feta 10 000 K, 'me lesela lefe kapa lefe la ceramic le phahameng le ka lokisoa, 'me lesela le na le boima bo botle le matla a ho kopanya a phahameng. Bothata ke hore bokhoni ba ho fafatsa bo phahame. Litšenyehelo tse tlase, le tse turang tsa lisebelisoa, le tsa matsete a hang feela li phahame.
Ho iketsetsa tlhahiso ea mocheso o phahameng (SHS) ke theknoloji ea ho kopanya thepa e ncha ka ho iketsetsa mocheso o phahameng oa lik'hemik'hale pakeng tsa li-reactants. E na le melemo ea lisebelisoa tse bonolo, ts'ebetso e bonolo, katleho e phahameng ea tlhahiso, tšebeliso e tlase ea matla le ho se silafatse. Ke theknoloji ea boenjiniere ba bokaholimo e loketseng haholo bakeng sa tšireletso ea lebota le ka hare la liphaephe. Lera la ceramic le lokisitsoeng ke SHS le na le litšobotsi tsa matla a ho kopanya a phahameng, ho thatafala ho phahameng le ho hanyetsa mafome, tse ka atolosang bophelo ba phaephe ka katleho. Karolo e ka sehloohong ea lesela la ceramic le sebelisoang liphaepheng tsa peterole ke Fe+Al2O3. Ts'ebetso ke ho kopanya phofo ea oxide ea tšepe le phofo ea aluminium ka har'a phaephe ea tšepe ka ho lekana, ebe e potoloha ka lebelo le phahameng holim'a centrifuge, ebe e hotetsoa ke tlhase ea motlakase, 'me phofo ea cha. Karabelo ea ho falla e etsahala ho theha lera le qhibilihisitsoeng la Fe+Al2O3. Lera le qhibilihisitsoeng le arotsoe ka tlas'a ts'ebetso ea matla a centrifugal. Fe e haufi le lebota le ka hare la phaephe ea tšepe, 'me Al2O3 e etsa lesela le ka hare la ceramic hole le lebota la phaephe.
