Say pormulasyon parad saray magaspang, medium, tan pinon SiC particles et nepeg ya 5:1:4. Say Black SiC so kaslakan ya napili bilang raw material parad panaggawa na silicon carbide bricks; say kemikal a komposisyon to et onia: SiC 98.0%, libren C 0.5%, Fe 0.2%, tan libren SiO2 0.6%. Say proseso na panaggawa et manduruma depende ed paraan na panag-bond. Saray antikey ya outline na saray proseso parad nanduruman paraan na panag-bond et singa onggendan:
(1) Silicon nitride-bonded silicon carbide bricks: Saray berdin laman ya naporma manlapud magaspang, medium, tan pinon SiC particles tan pinon silicon powder et pinaputok ed puron N2 ya atmospera ed 1370 degree. Saya so mamawala na laryo ya walay -SiC skeleton tan - tan -Si₃N₄ matrix. Walay daiset ya residual silicon tan SiO2 ya natilak ed matrix; say relatibon karga na sarayan kabiangan et manduruma unong ed manggagawa.
(2) Silicon carbide bricks: Say SiC, silicon powder, tan carbon powder et ilaok tan moldien unong ed sakey ya espisipikon ratio, insan pinaltog ed 1400℃diad sakey a reducing atmosphere. Diad maslak a kaso, say panagpaltog et gagawaen ya saray laryo et akaponpon ed carbon. Legan na panagpaltog, sakey a laryo ya walay -SiC skeleton tan pino-grained -SiC matrix so napapawala. Say -SiC et naporma ed reaksion na pino ya silicon powder ed pino ya carbon powder legan ya manpapaputok; sayan produkto et walaan met na daiset a residual silicon tan carbon.
(3) Silicon oxynitride-bonded silicon carbide bricks: No ipaparaan so batch parad sarayan bricks, say proporsyon na pinon silicon powder ya inusar et mas abeba nen say silicon carbide.
