Kupambana kwa Silicon Carbide Crucibles mu Ntchito Zotentha Kwambiri

Mpweya wa carbon silicon crucible, monga graphite crucible, ndi imodzi mwa mitundu yosiyanasiyana ya ma crucibles ndipo ili ndi ubwino wa machitidwe omwe ma crucible ena sangafanane. Pogwiritsa ntchito zida zapamwamba zotsutsa komanso njira zamakono zamakono, tapanga mbadwo watsopano wazitsulo zapamwamba za carbon-silicon crucibles. Ili ndi mawonekedwe a kuchuluka kwachulukidwe, kukana kutentha kwambiri, kusamutsa kutentha mwachangu, kukana kwa asidi ndi alkali, kulimba kwa kutentha kwambiri, komanso kukana kwa okosijeni mwamphamvu. Moyo wake wautumiki ndi katatu kuposa wadongo graphite crucibles. Ubwino wa magwiridwe antchitowa umapangitsa kuti ma crucibles a carbon silicon akhale oyenerera malo ogwirira ntchito omwe amatentha kwambiri kuposa ma graphite crucibles. Choncho, muzitsulo, kuponyera, makina, mankhwala ndi mafakitale ena, zitsulo za carbon-silicon zimagwiritsidwa ntchito kwambiri posungunula zitsulo zachitsulo ndi zitsulo zopanda chitsulo ndi ma alloys awo, ndipo zimakhala ndi phindu pazachuma.

Pali kusiyana ndi kugwirizana pakati pa carbon silicon crucibles ndi wamba graphite crucibles. Choyamba, ndizofanana: Mitsuko ya carbon-silicon imapangidwa pamaziko a crucibles wamba ndipo amagwiritsidwa ntchito kusungunula zitsulo zopanda chitsulo monga mkuwa, aluminiyamu, golidi, siliva, lead, ndi zinki. Njira zogwiritsira ntchito ndi zosungirako ndizofanana, choncho samalani ndi chinyezi ndi zotsatira pamene mukusunga.

Kachiwiri, kusiyana kuli pazida zomwe zimagwiritsidwa ntchito popanga silicon carbide crucibles, zomwe ndi zida za silicon carbide. Choncho, zimagonjetsedwa ndi kutentha kwakukulu ndipo zimatha kupirira kutentha mpaka madigiri 1860, kulola kugwiritsidwa ntchito mosalekeza mkati mwa kutentha kumeneku. The carbon silicon crucible ndi mankhwala opangidwa ndi isostatic kukanikiza ali ndi ubwino wapadera monga dongosolo yunifolomu, kachulukidwe mkulu, otsika sintering shrinkage, otsika nkhungu zokolola, mkulu kupanga dzuwa, mawonekedwe ovuta, mankhwala wochepa thupi, lalikulu ndi yeniyeni kukula, etc. kuponyera.
