1. Umqondo:Igama elithi “ceramics” elisetshenziswa nsuku zonke ngokuvamile libhekisela ezintweni zobumba noma izitsha zobumba;kwisayensi yezinto zokwakha, izitsha zobumba zibhekisela ezintweni zobumba ngomqondo obanzi, hhayi kuphela ezitsheni zansuku zonke ezifana nezitsha zobumba nezitsha zobumba, kodwa ezintweni ezingaphili ezingezona ezensimbi njengegama elivamile. noma evame ukubizwa ngokuthi “i-ceramics”.
2.Izici nezici:“amaceramic” ansuku zonke akudingeki achazwe kakhulu. Ngokuvamile, ziqinile, ziyaphuka, azikwazi ukugqwala futhi ziyavalela. I-Ceramics elabhorethri kanye nesayensi yezinto ezibonakalayo kodwa ayikhawulelwe ezicini eziqukethwe “kumaceramics” nsuku zonke, njengokumelana nokushisa (izitsha zobumba ezikwazi ukumelana nokushisa/ukumelana nomlilo), ukudlulisa ukukhanya (izinga) (izitsha zobumba ezibonisa ngale, ingilazi), i-piezoelectric ( i-piezoelectric ceramics), njll.
3.Izinjongo zocwaningo nokusebenzisa:Izitsha zobumba zasekhaya zivame ukukhiqizwa futhi zifundelwe izakhiwo zokuhlobisa ze-ceramics ngokwazo kanye nemisebenzi yazo njengeziqukathi. Vele, asetshenziswa futhi njengezinto zokwakha zokwakha, njengamathayela e-ceramic, ayingxenye yezinto zendabuko ezingezona ezensimbi ezaziwa kakhulu. Ekusetshenzisweni kwesayensi yezinto ezibonakalayo kanye nobunjiniyela, izinjongo zokucwaninga nezinto ezingezona ezensimbi ze-inorganic non-metallic nezinjongo zokusebenzisa zedlule kude izinto zendabuko, okungukuthi, ucwaningo nokuthuthukiswa kanye nokusetshenziswa ikakhulukazi kwezinye izici zezinto zokwakha, ezifana nezitsha zobumba ezivikela izinhlamvu ukuze kufundwe amandla ayo aphakeme kakhulu. , ukuqina kokumuncwa kwezinhlamvu zamandla, imikhiqizo yayo ehambisana nayo izivikelo zomzimba nezikhali zobumba, bese kuba izitsha zobumba ezingashi nokumelana nokushisa. Imfuneko ukuzinza kwayo kwezinga lokushisa eliphakeme, ukumelana ne-oxidation ephezulu lokushisa kanye nokufakwa kwe-thermal, kanye nemikhiqizo yayo ehambisanayo njengezitini eziphikisayo zesithando sokushisa esishisayo, izambatho eziphikisana nokushisa endaweni ye-rocket, i-thermal insulation coatings, njll.
4.Ifomu lezinto ezibonakalayo:umuzwa wokuzwa, i-ceramics ngokuyisisekelo "imise" ekuphileni kwansuku zonke, kanye nomqondo obonakalayo wezitsha, izitsha namathayili. Kusayensi yezinto zokwakha, izinto zobumba zihlukahlukene, njengezinhlayiya ze-silicon carbide emafutheni okugcoba, ukunamathela okumelana nomlilo endaweni yerokhethi, njll.
5.Ukwakheka Kwezinto Ezibalulekile (Ukwakheka):Izitsha zobumba zendabuko ngokuvamile zisebenzisa izinto zemvelo njengezinto ezingavuthiwe, njengobumba. Kwisayensi yezinto zokwakha, izitsha zobumba zisebenzisa izinto zemvelo kanye nezinto ezikhiqizwayo njengezinto zokusetshenziswa, njenge-nano-alumina powder, i-silicon carbide powder nokunye.
6.Ubuchwepheshe bokucubungula:I-ceramics yasekhaya kanye "nezinto ze-ceramic" zenziwa nge-sintering. Izinto ze-Ceramic zakhiwa ngezindlela zokwenziwa zamakhemikhali ngokwemikhiqizo ehlukene yokugcina, eminingi yayo engase ingahlobani nokucwiliswa.
