Zircon xuab zeb (zircon hmoov) yog siv nyob rau hauv refractories (xws li zirconium corundum cib thiab zirconium refractory fibers), Casting xuab zeb rau kev lag luam casting (precision casting xuab zeb), precision ceramic khoom, thiab kuj nyob rau hauv zus tau tej cov iav, hlau (sponge zirconium) thiab zirconium compounds ntau lawm (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, thiab lwm yam).

Khoom Description

Zircon, tseem hu ua zirconium silicate (ZrSiO4), yog ib qho khoom sib koom ua ke los ntawm kev tsuas thiab ua cov pob zeb ntxhia pob zeb hnyav thaum ub. Mined feem ntau hauv Australia thiab South Africa, zircon tuaj yeem siv rau hauv nws cov xuab zeb ntxhib los yog milled rau cov hmoov zoo. Nws cov khoom ua kom ntseeg tau tias nws tau siv ntau yam khoom siv niaj hnub, suav nrog cov vuas luaj ceramic thiab cov khoom siv kho mob, nrog rau muaj cov ntawv thov kev lag luam loj.
Zircon tuaj yeem ua tiav los tsim zirconia los ntawm melting cov xuab zeb ntawm qhov kub siab heev los ua cov zirconia molten, tseem hu ua zirconium oxide (ZrO2).

Zirconium, lwm qhov derivative ntawm zircon, yog cov tshuaj lom Zr nyob rau hauv Lub Sij Hawm Lub Sij Hawm thiab siv daim ntawv ntawm silvery grey hlau. Raws li 18th feem ntau cov khoom nyob rau hauv lub ntiaj teb crust, nws feem ntau tshwm sim nyob rau hauv cov ntxhia zircon nyob rau hauv silicate daim ntawv thiab, tsis tshua muaj heev, nyob rau hauv cov ntxhia baddeleyite nyob rau hauv daim ntawv oxide.
Zircon muaj cov ntsiab lus theoretical ntawm 67% zirconia thiab 32% silica thiab nws feem ntau tuaj yeem muaj ib feem me me ntawm hafnium hauv thaj tsam ntawm 0.2 mus rau 4%.

Daim ntawv thov:

Kev siv lub ntsiab ntawm zircon xuab zeb yog nws hloov dua siab tshiab rau hauv hmoov, opacifier, fused zirconia, zirconium tshuaj, tshuaj zirconia thiab zirconium hlau. Zircon xuab zeb yog siv ncaj qha rau hauv cov ntawv thov thiab cov refractories thiab lwm yam kev siv me.
