Es formen mat\u00e8ries primeres de gra gruixut i pols fines de SiC sota la protecci\u00f3 d'alta temperatura i certa pressi\u00f3; es recristal\u00b7litzen mitjan\u00e7ant sinteritzaci\u00f3 al buit, per evaporaci\u00f3 de les pols fines de SiC i coagulaci\u00f3 en part\u00edcules de SiC de gra gruixut. A continuaci\u00f3, s'obt\u00e9 carbur de silici recristal\u00b7litzat.A causa de la seva alta puresa (SiC > 99,51 %) i de l'abs\u00e8ncia de fase de lligam intermedi, t\u00e9 excel\u00b7lents propietats mec\u00e0niques a alta temperatura, i la temperatura de funcionament m\u00e0xima pot arribar als 1700 \u00b0C. El carbur de silici recristal\u00b7litzat t\u00e9 una bona resist\u00e8ncia a alta temperatura en productes cer\u00e0mics, i aquesta augmenta amb l'augment de la temperatura. B\u00e0sicament, no es contraeix. Al mateix temps, el carbur de silici recristal\u00b7litzat t\u00e9 una bona conductivitat t\u00e8rmica, resist\u00e8ncia als cops t\u00e8rmics, resist\u00e8ncia a l'oxidaci\u00f3 i resist\u00e8ncia a la corrosi\u00f3 \u00e0cid-b\u00e0sica. Per tant, el SiC recristal\u00b7litzat es pot fabricar en diverses formes geom\u00e8triques segons diferents usos, especialment en condicions d'alta temperatura.<\/p>\n

El SiC recristal\u00b7litzat \u00e9s adequat per a l'\u00fas com a mobiliari de forn i accessoris de forn en les ind\u00fastries de la cer\u00e0mica, els refractaris, la cer\u00e0mica el\u00e8ctrica, l'electr\u00f2nica i altres. Les seves caracter\u00edstiques notables s\u00f3n la seva estabilitat dimensional, la seva capacitat de resist\u00e8ncia a altes temperatures i un bon efecte d'estalvi d'energia. El SiC recristal\u00b7litzat es pot fabricar en forma de varetes, bigues buides, taules i peces de formes especials. Halsic r tamb\u00e9 t\u00e9 una bona capacitat anti-oxidaci\u00f3 i anti-erosi\u00f3, una alta duresa i resist\u00e8ncia al desgast. Halsic r es pot utilitzar en la metal\u00b7l\u00fargia, la maquin\u00e0ria, la ind\u00fastria qu\u00edmica i la ind\u00fastria militar.<\/p>\n
