Impembelelo ye Isilicon khabhayithi (SiC) kwiipropati zee-castables

⑴ Ekubeni i-SiC ngokwayo ingenawo amanzi, akulula ukumanziswa, kwaye akulula ukwenza umaleko wefilimu wamanzi, kunye nokusetyenziswa kwamanzi okuphoswa kwanda. Ngako oko, umxholo we-SiC uphezulu, ukungasebenzi kakuhle kunye ne-fluidity ye-castable, kunye namandla okubanda okuguquguqukayo kuya kuncipha.

⑵ Ekubeni ubuninzi be-SiC (2.6 ~ 2.8g / cm3) bukhulu kunobuninzi beekeramics (2.2 ~ 2.4g / cm3), umxholo we-SiC eninzi, ubuninzi bomthamo wezinto eziphathekayo. Xa izinga lokushisa liphakama kwaye umxholo we-SiC uphezulu, ubuninzi bomthamo buya kunyuka kwinqanaba elithile. Umxholo weSiC ubonisa ixabiso elibi kwimpembelelo yokutshintsha komgca wezinto eziphathekayo.

⑶ Umxholo we-SiC unenzuzo kumandla okuphosa, ngakumbi kwiqondo lokushisa eliphezulu (1100 ° C). Ngokukodwa xa ubukhulu be-SiC buyi-150 ye-mesh, ayinakho i-oxidized ngokupheleleyo, kwaye ezinye izikhewu zenziwe malunga neengqungquthela ze-SiC, eziphucula ukuxhathisa ukothuka kwe-thermal kunye namandla okuphosa. I-SiC engabonakaliyo iphinda isebenze njengento yokuqinisa i-particle.

⑷ Okukhona umxholo we-SiC, kokukhona uphucula ukusebenza kwesixhobo sokuchasa ulusu.

⑸ Okukhona umxholo we-SiC, kokukhona uxhathisa i-alkali.
