Karburimi i sinteruar i silicit konsiderohet si metoda m\u00eb premtuese p\u00ebr sinterimin e SiC. Qeramika e karburit t\u00eb silicit me madh\u00ebsi t\u00eb madhe dhe form\u00eb komplekse mund t\u00eb p\u00ebrgatitet p\u00ebrmes procesit t\u00eb sinterimit atmosferik. Korporata GE e Shteteve t\u00eb Bashkuara ka adoptuar masat e m\u00ebposhtme: \u03b2 \u2013 Shtimi i borit dhe karbonit n\u00eb SiC, sinterimi n\u00eb atmosfer\u00eb inert mbi 2000 \u2103, dhe marrja e karbidi i silikonit t\u00eb sinteruar me dend\u00ebsi m\u00eb t\u00eb lart\u00eb se 98% n\u00eb 2020 \u2103. Me Y2O3 dhe Al2O3 si ndihm\u00ebs p\u00ebr sinterim dhe YAG (Y3Al5O12) me pik\u00eb t\u00eb ul\u00ebt t\u00eb shkrirjes si p\u00ebrb\u00ebr\u00ebs baz\u00eb, Instituti i Silikateve i Shangait, Akademia Kineze e Shkencave, pjeki qeramik\u00ebn e karbhidit t\u00eb silicit me rezistenc\u00eb p\u00ebrkuljeje dhe rezistenc\u00eb ndaj thyerjes prej 707 dhe 10.7 p\u00ebrkat\u00ebsisht n\u00eb 1850 \u2103. Liu Baoying nga Instituti i K\u00ebrkimit dhe Projektimit t\u00eb Silikateve t\u00eb Shandongut shtoi sasin\u00eb e duhur t\u00eb Al2O3 dhe Y2O3 si shtesa p\u00ebr sinterim, dhe prodhoi materiale qeramike kompozite SiC me dend\u00ebsi relative 97% n\u00eb 1780 \u2103 duke p\u00ebrdorur procesin e formimit me mbeturina, t\u00eb cilat mund t\u00eb plot\u00ebsojn\u00eb nevojat e prodhimit industrial t\u00eb vulave mekanike dhe qeramikave rezistente ndaj konsumit. Por deri tani, k\u00ebrkimi mbi karbidi i silicit t\u00eb sinteruar nuk \u00ebsht\u00eb shum\u00eb i thelluar, gj\u00eb q\u00eb duhet t\u00eb thellohet m\u00eb tej.<\/p>\n
