Cov tshuaj tiv thaiv Bonded Silicon Carbide
Reaction bonded silicon carbide compositions tau tsim los rau qhov zoo tshaj plaws lub zog thiab corrosion kuj. Cov txiaj ntsig ntawm kev siv cov tshuaj tiv thaiv kev sib koom ua ke silicon carbide suav nrog: tshwj xeeb hnav tsis kam, lub neej ntev vim nws zoo heev tiv thaiv oxidation, zoo heev thermal shock resistance, thiab loj los yog me me txoj kev muaj peev xwm.
Nitride Bonded Silicon Carbide
Silicon nitride bonded silicon carbide yog tsim los rau kev hnav tsis kam. Nws tuaj yeem tsim rau hauv cov duab sib txawv heev vim nws cov yam ntxwv castable thiab kuj muaj qhov xav tau refractory thiab tshuaj lom neeg. Nws qhov kev siv tseem ceeb yuav yog qhov uas xav tau kev hnav siab tshaj plaws lossis qhov twg cov duab yog qhov sib txawv heev los ua rau hauv lwm cov khoom sib xyaw. Ob chav raug rho tawm haujlwm uas muaj tsawg qhib porosity thiab txhim kho oxidation kuj tseem muaj.
Sintered Silicon Carbide
Sintered alpha silicon carbide yog tsim los ntawm sintering ultra-ntshiab submicron hmoov. Cov hmoov no yog tov nrog cov khoom siv uas tsis yog oxide sintering, tom qab ntawd tsim rau hauv cov duab nyuaj los ntawm ntau txoj kev thiab sib sau ua ke los ntawm sintering ntawm qhov kub siab tshaj 3632 ° F.
Cov txheej txheem sintering ua rau ib theem zoo-grained silicon carbide uas yog ntshiab thiab zoo ib yam, nrog zoo tsis muaj porosity ua rau cov ntaub ntawv los tiv thaiv corrosive ib puag ncig, abrasive ib puag ncig, thiab ib puag ncig ua haujlwm kub (2552 ° F). Cov khoom no ua rau sintered alpha silicon carbide zoo tagnrho rau kev siv xws li tshuaj lom neeg thiab slurry twj tso kua mis thiab bearings, nozzles, twj tso kua mis thiab valve trim, ntawv thiab textile Cheebtsam, thiab lwm yam.
