Zirconia, tseem hu ua zirconium dioxide, feem ntau ua tiav siv txoj kev hu ua "kev ua hmoov nplej." Qhov no suav nrog ntau cov kauj ruam, suav nrog:

1. Calcining: Cua sov zirconium tebchaw rau qhov kub thiab txias los tsim zirconium oxide hmoov.

2. Sib tsoo: Sib tsoo cov calcined zirconia kom ua tiav qhov xav tau qhov loj me thiab kev faib tawm.

3. Shaping: Cov hmoov av zirconia yog tom qab ntawd ua rau hauv cov duab uas xav tau, xws li pellets, blocks lossis cov duab kev cai, siv cov txheej txheem xws li nias lossis casting.

4. Sintering: Cov zoo li zirconia yog sintered ntawm qhov kub thiab txias kom ua tiav qhov kawg ntom ntom siv lead ua qauv.

5. Kev Ua tiav: Sintered zirconia tuaj yeem dhau los ua cov kauj ruam ntxiv xws li kev sib tsoo, polishing thiab machining kom ua tiav qhov xav tau ntawm qhov chaw tiav thiab qhov tseeb.

Cov txheej txheem no muab zirconia cov khoom muaj zog, hardness thiab hnav tsis kam, ua rau lawv haum rau ntau yam kev siv hauv kev lag luam xws li aerospace, kev kho mob thiab engineering.

Zircon yog zirconium silicate ntxhia uas feem ntau ua tiav siv kev sib xyaw ua ke ntawm kev sib tsoo, sib tsoo, sib nqus sib nqus thiab nqus cov txheej txheem sib cais. Tom qab muab rho tawm los ntawm cov ore, zircon yog ua tiav kom tshem tawm impurities thiab cais nws los ntawm lwm yam minerals. Qhov no suav nrog crushing cov ore mus rau qhov loj me thiab tom qab ntawd sib tsoo kom ntxiv txo qhov me me. Sib nqus sib cais yog siv los tshem tawm cov hlau nplaum sib nqus, thiab lub ntiajteb txawj nqus sib cais tshuab yog siv los cais zircon los ntawm lwm cov ntxhia hnyav. Cov txiaj ntsig zircon concentrate tuaj yeem ua kom zoo ntxiv thiab ua tiav rau kev siv ntau yam kev lag luam.

Cov khoom siv raw rau kev tsim cov zirconium feem ntau suav nrog zircon xuab zeb (zirconium silicate) thiab baddeleyite (zirconia). Zircon xuab zeb yog thawj qhov chaw ntawm zirconium thiab yog mined los ntawm ntxhia xuab zeb deposits. Baddeleyite yog ib daim ntawv tshwm sim ntawm zirconium oxide thiab yog lwm qhov chaw ntawm zirconium. Cov ntaub ntawv nyoos no tau ua tiav los rho cov zirconium, uas tom qab ntawd siv ntau yam kev lag luam, suav nrog kev tsim cov zirconium hlau, zirconium oxide (zirconia) thiab lwm yam zirconium tebchaw.
