Babban Amfanin Silicon Carbide

Baƙar fata siliki carbide an yi shi ne daga yashi quartz da kuma man coke silica a matsayin babban albarkatun ƙasa ta hanyar narkewar zafin jiki a cikin tanderun juriya. Taurinsa yana tsakanin corundum da lu'u-lu'u, ƙarfin injinsa ya fi corundum girma, kuma yana da karye da kaifi. Koren silicon carbide ana yin shi ne daga coke na man fetur da silica a matsayin babban albarkatun ƙasa, tare da ƙara gishiri a matsayin ƙari, kuma ana narkar da shi a babban zafin jiki a cikin tanderun juriya. Taurinsa yana tsakanin corundum da lu'u-lu'u, kuma ƙarfin injinsa ya fi corundum girma.

Don haka menene babban amfanin silicon carbide?
1. Abrasives - Yafi saboda silicon carbide yana da babban tauri, sinadarai kwanciyar hankali da wasu tauri, silicon carbide za a iya amfani da su ƙera bonded abrasives, mai rufi abrasives da free nika sarrafa gilashin da yumbu. , dutse, jefa baƙin ƙarfe da wasu maras ferrous karafa, carbide, titanium gami, high-gudun karfe sabon kayan aikin da nika ƙafafun, da dai sauransu.

2. Refractory kayan da lalata-resistant kayan --- Yafi saboda silicon carbide yana da wani babban narkewa batu (digiri na bazuwa), sinadaran inertness da thermal girgiza juriya, silicon carbide za a iya amfani da abrasives da yumbu samfurin harbe kilns. Zubar da faranti da saggers, tubalin silicon carbide don murhun silinda distillation tanderu a masana'antar smelting na zinc, rufin tantanin halitta na aluminum electrolytic, crucibles, ƙananan kayan tanderu da sauran samfuran yumbu na silicon carbide.

3. Abubuwan amfani da sinadarai-saboda siliki carbide na iya bazuwa a cikin narkakkar karfe da amsa tare da oxygen da ƙarfe oxides a cikin narkakkar karfe don samar da carbon monoxide da silicon-dauke da slag. Saboda haka, ana iya amfani da shi azaman wakili mai tsarkakewa don narkewar karfe, wato, azaman deoxidizer da simintin simintin gyaran ƙarfe don yin ƙarfe. Wannan gabaɗaya yana amfani da ƙarancin ƙarancin siliki carbide don rage farashi. Hakanan za'a iya amfani dashi azaman ɗanyen abu don kera silicon tetrachloride.

4. Aikace-aikacen lantarki - ana amfani da su azaman abubuwa masu dumama, abubuwan juriya marasa daidaituwa da manyan kayan semiconductor. Abubuwan dumama kamar sandunan carbon carbon (wanda ya dace da tanderun lantarki daban-daban da ke aiki a 1100 zuwa 1500 ° C), abubuwan da ba na layi ba, da bawul ɗin kariya na walƙiya daban-daban.
