Deqing Yehui Ceramic Parts Manufacture Co., Ltd. yog nyob rau hauv Deqing county, Huzhou City, ZheJiang Province, Suav.Nws yog kwv yees li 200km deb ntawm Shanghai seaport, peb tshwj xeeb hauv kev tsim Zirconia Ceramics thiab Alumina Ceramic qhov chaw nrog 10 xyoo.
Kev kub siab ua haujlwm ntawm cov qauv ceramics feem ntau zoo dua, feem ntau qis dua 800 ° C, thiab qhov kub thiab txias tsis cuam tshuam rau lub zog ntawm cov khoom siv ceramic.Piv nrog covalent daim ntawv cog lus ceramics, ion-bonded ceramics muaj qhov tsis zoo kub tsis kam.Feem ntau hais lus, nyob rau hauv qhov kub thiab txias, qhov tawg tsis ua hauj lwm ntawm ceramics yog nkig tus cwj pwm, uas yog, tsis muaj yas deformation, thiab qhov kawg strain yog heev me me, thiab nws yog heev rhiab heev rau me me defects.Txawm li cas los xij, nyob rau hauv qhov chaw kub kub, ceramics tuaj yeem tsim cov yas me me deformation ua ntej tawg, qhov kawg strain tau nce siab heev, thiab muaj tus cwj pwm elastoplastic me me.Tsis tas li ntawd, qhov rhiab heev ntawm lub zog rau qhov tsis xws luag txawv heev.Qhov ciam teb ntawm thaj chaw uas tsis muaj qhov kub thiab txias qhov chaw uas ua rau cov khoom siv hloov pauv no feem ntau hu ua brittle ductility transition temperature.Lub brittle ductility hloov pauv kub yog ze ze rau cov tshuaj ceramic muaj pes tsawg leeg thiab hom valence daim ntawv cog lus.Muaj feem xyuam, tab sis kuj muaj feem xyuam rau lub microstructure ntawm cov ceramic, muaj pes tsawg leeg ntawm grain ciam theem, tshwj xeeb tshaj yog muaj pes tsawg leeg thiab cov ntsiab lus ntawm grain ciam iav theem.Thaum qhov kub thiab txias, siab tshaj qhov hloov pauv ntawm qhov kub thiab txias, lub zog ntawm cov khoom siv ceramic feem ntau yuav txo qis.Rau ion-bonded MgO ceramics, lub ductility hloov pauv kub yog qhov tsawg heev, thiab lub zog txo qis nrog qhov nce ntawm qhov kub yuav luag los ntawm chav tsev kub.Lub brittle ductility hloov pauv kub ntawm Al2O3 yog hais txog 900 ° C, lub brittle ductility hloov pauv kub ntawm kub xovxwm sintered Si3N4 yog hais txog 1200 ° C, thiab SiC ceramics feem ntau tuaj yeem tiv taus kub ntawm 1600 ° C.
