Kaddarorin siliki-carbide mai amsawa da babban amfani? Silicon carbide kuma ana iya kiransa carborundum ko yashi mai hana wuta, wani fili ne na inorganic, ya kasu kashi koren siliki carbide da silikon carbide na baki biyu. Shin kun san kaddarorin da manyan amfanin silicon carbide? A yau, za mu gabatar da kaddarorin da manyan amfani da silicon carbide.
Reactive sintering silicon carbide ne amfani da ma'adini yashi, calcined man fetur coke (ko coal coking), itace slag (samar da kore silicon carbide bukatar ƙara abinci gishiri) da sauran albarkatun kasa, ta hanyar lantarki dumama tanderu ci gaba da zafi zafi.
Abubuwan halayen silicon carbide mai amsawa:
1. Thermal watsin da thermal fadada coefficient na silicon carbide. A matsayin wani nau'i na kayan haɓakawa, tubalin carbonized yana da kyakkyawan juriya ga girgiza. Ana bayyana wannan a cikin ƙaƙƙarfan ƙaƙƙarfan ƙayyadaddun yanayin zafi (madaidaicin canjin zafi) da ƙarancin ƙarancin haɓakar haɓakar thermal.
2, conductivity na silicon carbide. Silicon carbide abu ne na semiconductor, ƙarfinsa ya bambanta da nau'in da adadin ƙazantattun da aka gabatar a cikin crystallization, kuma juriya yana tsakiyar 10-2-1012Ω · cm. Daga cikin su, aluminium, nitrogen da boron suna da tasiri mai yawa akan tafiyar da aikin silicon carbide, kuma tafiyar da siliki carbide tare da ƙarin aluminum yana ƙaruwa sosai.
3. Juriya na silicon carbide. Juriya na siliki carbide yana canzawa tare da canjin yanayin zafi, amma a cikin wani takamaiman yanayin zafin jiki da halayen yanayin zafin ƙarfe na resistor suna juyawa. Dangantaka tsakanin juriya da zafin jiki na silicon carbide ya fi rikitarwa. Ƙarƙashin halayen silicon carbide na amsawa yana ƙaruwa tare da zafin jiki yana tashi zuwa wani ƙima, kuma ƙaddamarwa yana raguwa lokacin da zafin jiki ya sake tashi.
Amfani da silicon carbide:
1, lalacewa-resistant kayan - yafi amfani da su yi yashi dabaran, nika sandpaper, whetstone, nika dabaran, nika manna da photovoltaic kayayyakin a photovoltaic Kwayoyin, photovoltaic Kwayoyin da aka gyara surface nika, nika da polishing.
2, high-karshen refractory abu - za a iya amfani da a matsayin metallurgical masana'antu deoxidizer da lalata resistant kayan, don yin m high zafin jiki kiln prefabricated aka gyara, gyarawa sassa, da dai sauransu.
3, yumbu mai aiki - ba wai kawai zai iya rage girman kiln ba, amma kuma inganta ingancin samfuran kiln masana'antu, rage lokacin sake zagayowar, shine manufa kai tsaye abu don yumbu glaze sintering, ci gaba da high zafin jiki ba oxide tukwane, nuna sintered ain.
4, rare karafa - baƙin ƙarfe da karfe Enterprises, metallurgical masana'antu concentrator filin, da wani aikace-aikace.
5, wasu - amfani da su don yin nisa-infrared radiation shafi ko silicon carbide farantin nesa-infrared radiation bushewa.
Silicon carbide saboda santsi Organic sinadaran Properties, high zafi canja wurin coefficient, kananan mikakke fadada coefficient, mai kyau lalacewa juriya, ban da sa resistant kayan, akwai wasu sauran manyan amfani, kamar: tare da wani sabon tsari zuwa silicon carbide foda manne a cikin. da centrifugal impeller ko Silinda jiki rami, iya inganta lalacewa juriya da kuma kara da sabis na 1 zuwa 2 sau; An yi amfani da shi don yin kayan haɓaka mai girma, babban juriya na zafin jiki, ƙananan girman, nauyin haske da ƙarfin ƙarfi, kariyar muhalli da tasirin ceton makamashi a bayyane yake. Silicone carbide low-grade (wanda ya ƙunshi kusan 85% SiC) wakili ne mai kyau na deoxidizing, wanda za'a iya amfani dashi don haɓaka ƙimar ƙarfe na ƙarfe, kuma yana da amfani don sarrafa abun da ke ciki da haɓaka ingancin ƙarfe. Bugu da kari, silicon carbide kuma ana amfani da shi don yin yawancin kayan dumama wutar lantarki sandar molybdenum silicon.
