Kayan Gilashin Tsarin Mu Na Musamman Sun Haɗa da Nau'ukan Masu zuwa
1. Silicon Nitride Ceramics
Silicon nitride yumbu wani sabon nau'in yumbu na injiniya ne, wanda shine bambanci daga yumbu na silicate na yau da kullun cewa haɗin nitrogen da silicon a cikin tsohon yana cikin haɗuwa da kaddarorin haɗin gwiwa, don haka yana da halaye na ƙarfin ɗauri mai ƙarfi da ingantaccen rufi. .
Ƙarfin silicon nitride yana da girma sosai, taurin kuma yana da girma sosai, yana ɗaya daga cikin abubuwa mafi wuya a duniya, ƙarfin zafinsa yana da kyau, ana iya kiyaye ƙarfin zuwa 1200 ° C ba tare da faduwa ba, har sai 1900 ° C zai bazu. , kuma yana da ban mamaki sunadarai juriya, amma kuma high-yi lantarki rufi abu, The overall yi na daban-daban na silicon nitride yumbu kayayyakin samar da microwave sintering tsari ya kai ga kasa da kasa ci-gaba matakin.
2. Aluminum Nitride Ceramics
Theoretical theormal watsin conductivity ne 320W / m · k, game da 80% na thermal watsin na jan karfe, yayin da aluminum nitride yana da low dielectric akai-akai, high juriya, low yawa da kuma kusa da thermal fadada coefficient na silicon, da m yi ne mafi alhẽri daga Al2O3. , BeO, SiC ... da dai sauransu, ana amfani da high thermal conductivity insulator da lantarki substrate kayan. Kamfanin yana samar da nau'o'in yumbura na aluminum nitride tare da ƙananan girma fiye da 3.25, da kuma yanayin zafi na 120 ~ 200W / m · K, Aluminum nitride ceramics za a iya samar da su a cikin wasu ƙayyadaddun bayanai bisa ga buƙatun.
3. Alumina Ceramics
Alumina yumbura (corundum na wucin gadi) wani abu ne na tsarin zafin jiki mai girman gaske. Its narkewa batu ne sosai high, za a iya amfani da matsayin high-sa refractory kayan, kamar crucible, high zafin jiki tanderu tube. Yin amfani da fa'idodin taurin alumina, yana yiwuwa a kera injunan niƙa corundum da ake amfani da su a cikin dakin gwaje-gwaje don niƙa kayan da ƙarancin taurinsa. Tare da manyan kayan albarkatu masu tsabta, amfani da fasaha na ci gaba, kuma na iya yin yumbu alumina a bayyane, yana iya samar da bututun fitilar sodium mai matsa lamba.
4. Silicon Carbide Ceramics
Silicon carbide ceramics kuma abu ne mai mahimmanci na tsari, nau'in nau'in abu ne mai ƙarfi, ƙaramin yawa, kansa yana da lubricity, kuma yana sa juriya, ban da hydrofluoric acid, baya amsawa tare da sauran inorganic acid, juriya na lalata; Hakanan yana tsayayya da iskar oxygen a yanayin zafi mai yawa. Bugu da ƙari, yana iya tsayayya da girgiza sanyi da zafi, mai zafi zuwa fiye da 1000 a cikin iska, mai sanyi sosai sannan kuma mai tsanani mai tsanani, kuma ba zai rushe ba. Nitride silicon nitride ne wanda ke da kyawawan halaye wanda galibi ana amfani da shi don kera kayan aikin injiniya kamar bearings, ruwan injin turbine, zoben rufe injiniyoyi, da gyare-gyaren dindindin.
5. Ceramics mara kyau
Tare da porosity na 35-40% da girman pore na 0.5-100um, ana iya amfani da shi don rabuwa da numfashi ko m-ruwa da rabuwa da gas. Kayan yumbu ne na ci gaba.
