Zvivakwa zveZirconia Ceramics

Zirconia ceramics (ZrO2), ine yakakwira kunyungudika, kuomarara kwakanyanya, yakanakisa kupfeka kuramba, se insulator pane yakajairika tembiricha, uye pakakwirira tembiricha ine conductive zvivakwa. Yakachena ZrO2 ichena, yero kana grey kana iine tsvina, uye kazhinji ine HfO2, iyo isiri nyore kupatsanura. Zirconia inowanzocheneswa kubva kune zirconium ore.

Zirconia ine marudzi matatu emakristasi: yakaderera-tembiricha monoclinic crystal (m-ZrO2), yepakati-tembiricha tetragonal crystal (t-ZrO2), yakakwirira-tembiricha cubic crystal (c-ZrO2), ari pamusoro apa matatu makristasi aripo munzvimbo dzakasiyana tembiricha. uye inogona kushandurirwa kune mumwe nemumwe.

Zirconia ceramics rudzi rutsva rwemhando yepamusoro-tech ceramics, kuwedzera kune simba rakakwirira, kuoma, kupisa kwepamusoro, asidi uye alkali corrosion resistance uye kugadzikana kwemakemikari, panguva imwe chete nekudzivisa kwekutanga, kusina kudzivirira kwechiratidzo, kushanda kwakanakisisa kwekupisa kupisa. , nepo machinability, yakanaka chitarisiko mhedzisiro, yakakodzera kugadzirwa kwehuwandu.

1. High melting point

Nzvimbo yakanyunguduka ye zirconia i2715 ℃, uye iyo yakakwira kunyungudika uye kusagadzikana kwemakemikari kunoita kuti zirconia ive yakanaka refractory zvinhu.

2. kuoma kwepamusoro, kunaka kupfeka kusagadzikana

Zirconia ceramics dzine kuoma kwepamusoro uye zviri nani kupfeka kuramba. Kubva pane chaiyo data, iyo Mohs kuoma kwe zirconia ceramics ingangoita 8.5, iri padyo zvakanyanya nekuoma kweMohs yesafire 9.

3. simba uye kuomarara zvakati wandei

Zirconia ceramics dzine simba guru (kusvika ku1500MPa).

4. yakaderera thermal conductivity, yakaderera kuwedzera coefficient

Thermal conductivity ye zirconia ndiyo yakaderera mune zvakajairika ceramic zvinhu (1.6-2.03W/ (mk)), uye iyo coefficient yekuwedzera kwekupisa iri pedyo neiyo yesimbi. Naizvozvo, zirconia ceramics dzakakodzerwa nekugadzirwa kweceramic zvinhu.

5. kushanda zvakanaka kwemagetsi

Iyo dielectric inogara ye zirconia ndeye 3 nguva yesafire, iyo siginecha inonyanya kunzwisiswa, uye inonyanya kukodzera kune zvigunwe zvekuzivikanwa zvigamba. Zvichienderana nemaonero ekudzivirira kunyatsoita, zirconia ceramics, sechinhu chisiri-simbi, haina kudzivirira pamagetsi emagetsi masaini, uye haizokanganisa iyo yemukati antenna dhizaini, iyo inogona kubatanidzwa nyore nyore uye kuchinjika kunguva ye5G.
