Silicon nitride bonded silicon carbide ncej

Silicon nitride bonded silicon carbide

Si3N4 bonded SiC ceramic refractory khoom, yog tov nrog siab ntshiab SIC zoo hmoov thiab Silicon hmoov, tom qab plam casting chav kawm, cov tshuaj tiv thaiv sintered nyob rau hauv 1400 ~ 1500 ° C. Thaum lub sij hawm sintering, sau lub siab ntshiab Nitrogen rau hauv lub cub tawg, ces cov silicon yuav hnov ​​​​mob nrog Nitrogen thiab tsim Si3N4, Yog li Si3N4 bonded SiC cov khoom yog tsim los ntawm silicon nitride (23%) thiab silicon carbide (75%) raws li cov ntaub ntawv tseem ceeb. , sib tov nrog cov khoom siv organic, thiab zoo li tus sib tov, extrusion los yog pouring, ces ua tom qab ziab thiab nitrogenization.

Nta thiab qhov zoo:

1.High kub kam rau ua
2.High thermal conductivity thiab poob siab tsis kam
3.High mechanical zog thiab puas kuj
4.Excellent zog efficiency thiab corrosion kuj

Peb muab cov khoom zoo thiab precision machined NSiC ceramic Cheebtsam uas txheej txheem los ntawm

1.Slip casting
2. Extruding
3.Uni Axial nias
4.Isostatic nias
