Ceramic raj feem ntau yog tsim los ntawm cov khoom siv xws li alumina ceramics thiab silicon carbide ceramics. Alumina ceramics yog tus cwj pwm los ntawm kev hnav tsis kam, siab hardness, tsis kam oxidation thiab corrosion, thiab lub zog tshwj xeeb nyob rau hauv ntau qhov kub thiab txias -los ntawm huab cua kub mus rau qhov txias txias. Silicon carbide ceramic kav, hloov pauv, muaj kev hnav zoo heev, tiv thaiv kev yaig, thiab qee qhov kev tiv thaiv thermal shock.
Ntau txoj hauv kev tau ua haujlwm rau kev tsim cov khoom siv ceramic, suav nrog kev nias qhuav, plam casting, extrusion, txias isostatic nias, txhaj tshuaj molding, daim kab xev casting, kub nias, thiab kub isostatic nias. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb hauv tsev thiab thoob ntiaj teb tau tsim cov txheej txheem tsim ntxiv, xws li lim xovxwm, ncaj qha coagulation casting, gel casting, centrifugal slip casting, thiab khoom freeform fabrication. Txoj kev tsim tshwj xeeb xaiv nyob ntawm cov khoom tsim, qhov ntev, geometric complexity, thiab xav tau precision. Zirconia ceramic raj feem ntau raug rho tawm haujlwm ntawm qhov kub ntawm 800℃txog 1000 degree, hos alumina ceramic raj yog tsim los ntawm firing kaolin ntawm qhov kub ntawm 1600℃thiab 2000 degree. Lub voj voog ntau lawm rau cov raj ceramic yog qhov ntev, thiab qib ntawm kev siv tshuab thiab automation nyob rau hauv cov txheej txheem tsim khoom tseem qis dua. Tsis tas li ntawd, cov txheej txheem tsim khoom suav nrog kev siv cov khoom siv siab heev-xws li gypsum pwm, saggers, thiab boron nitride phaj- nrog rau kev siv hluav taws xob tseem ceeb hauv daim ntawv thee, nkev roj, thiab hluav taws xob; yog li ntawd, kev tsim cov raj ceramic yog qhov ua tau raws li cov txheej txheem{11}}raws li kev tsim khoom nrog cov qib qis ntawm kev ua haujlwm txuas ntxiv.
