Mene ne bambanci tsakanin silinda carbide da aka haɗa da amsawar amsawa da kuma sintered silicon carbide?

Idan ana maganar tukwanen silicon carbide, akwai manyan nau'i biyu:reaction bonding silicon carbideda kuma sintered silicon carbide. Duk da cewa nau'ikan yumbu guda biyu suna ba da ƙarfin juriya da juriya ga lalacewa, akwai wasu muhimman bambance-bambance tsakanin su biyun.

Bari mu fara da yumbu mai haɗin silicon carbide. Waɗannan yumbu suna tsakanin kashi 85% zuwa 90% na silicon carbide kuma suna ɗauke da wasu silicon. Matsakaicin juriyar zafinsu shine 1380°C. Ɗaya daga cikin manyan fa'idodin yumbu mai haɗin silicon carbide shine cewa ana iya tsara su zuwa manyan girma da siffofi. Wannan yana sa su zama kayan da suka dace don ƙirƙirar samfura na musamman da ƙwararru. Bugu da ƙari, ƙarancin faɗuwa da kyakkyawan juriyar lalacewa na waɗannan yumbu ya sa su zama zaɓi mai shahara a masana'antar haƙar ma'adinai.

Carbide ɗin silicon mai sintered mara matsi yana da babban abun ciki na silicon carbide, wanda zai iya kaiwa sama da kashi 99%, kuma mafi girman juriyar zafin jiki shine 1650°C. Ana gabatar da wani adadin faɗaɗawa yayin aikin sintering, wanda ke sa SiC mara matsi ya zama mafi dacewa don ƙera sassan SiC daidai. Saboda babban daidaitonsa, galibi ana amfani da carbide ɗin silicon mai sintered mara matsi don ƙera molds da sassan daidaito masu jure lalacewa.

Baya ga daidaiton ƙira da sassan lalacewa, kayan aikin murhu masu inganci na masana'antar sinadarai na iya amfani da juriyar zafin jiki mai kyau na simintin silicon carbide mara matsi. Ga waɗanda ke neman ingantattun bututun musanya zafi don kayan aikin sarrafa sinadarai, simintin silicon carbide mara matsi tabbas zaɓi ne mai kyau na kayan aiki.

Gabaɗaya, haɗakar amsawa da kuma haɗa sintering ba tare da matsin lamba ba na tukwanen SiC, kodayake kowannensu yana da fa'idodi da rashin amfaninsa, sun dace da masana'antu da aikace-aikace daban-daban. Idan kuna buƙatar samfuri na musamman ko mafi girma wanda zai iya jure lalacewa, tukwanen silicon carbide masu haɗin kai na iya zama zaɓin da ya dace a gare ku. Don ƙarin sassa masu laushi waɗanda ke buƙatar jure yanayin zafi mai yawa, tukwanen silicon carbide marasa matsi na iya zama zaɓi mafi kyau. Ko da wane nau'in tukwanen silicon carbide kuka zaɓa, kuna iya tabbata zai samar da dorewa da dorewar aikinku yana buƙata.
