Silicon Carbide

Silicon carbide abu ne mai wuyar gaske (Mohs hardness 9.25), ba ya narkewa kuma baya narkewa. Silicon Carbide yana da high thermal conductivity, low coefficient of thermal expansion, thermal shock and abrasion resistant kuma yana da ƙarfi a babban yanayin zafi. Silicon carbide daban-daban kaddarorin sa ya zama ingantaccen abu a aikace-aikace daban-daban.
Silicon carbide yana ƙunshe da nau'ikan asali guda biyu na yau da kullun: siliki carbide baƙar fata da carbide silicon carbide. Bakin siliki carbide ya ƙunshi sic kusan 95%, don haka taurin ya fi koren silicon carbide. An yadu amfani da sarrafa low tensile ƙarfi abu kamar gilashin, tukwane, dutse, refractory abu, jefa baƙin ƙarfe da kuma nonferrous karfe da dai sauransu Green silicon carbide ƙunshi sic game da 97% sama da kyau kai kaifi, don haka ana amfani da sarrafa wuya gami. , titanium gami da gilashin gani da kuma silinda jaket da lafiya nika yankan kayan aikin.

Amfani:
Silicon carbide yana da ingantaccen kaddarorin sinadarai, haɓakar zafin jiki mai ƙarfi, ƙarancin haɓaka haɓakar thermal, da juriya mai kyau. Bugu da ƙari, ana amfani da shi azaman abrasives, akwai wasu amfani da yawa, irin su: shafa silicon carbide foda a kan turbine impellers ko silinda tubalan tare da tsari na musamman Bangon ciki zai iya inganta juriya na lalacewa kuma ya tsawaita rayuwar sabis ta 1 ~ 2 sau. ; kayan da aka yi da shi da aka yi da shi yana da juriya na zafi mai zafi, ƙananan ƙananan, nauyin nauyi da ƙarfin ƙarfi, kuma yana da tasiri mai kyau na ceton makamashi. Low-grade silicon carbide (wanda ya ƙunshi kusan 85% SiC) kyakkyawan deoxidizer ne. Yana iya hanzarta saurin ƙera ƙarfe, da sauƙaƙe sarrafa abubuwan sinadaran da haɓaka ingancin ƙarfe. Bugu da ƙari, silicon carbide kuma ana amfani da shi sosai don yin sandunan siliki na siliki don abubuwan dumama lantarki.
