Feem ntau zircon yog siv ncaj qha rau hauv daim ntawv thov kev lag luam, tab sis ib feem me me yog hloov mus rau hlau. Feem ntau Zr hlau yog tsim los ntawm kev txo qis ntawm cov zirconium (IV) chloride nrog magnesium hlau nyob rau hauv cov txheej txheem Kroll. Lub resulting hlau yog sintered kom txog thaum txaus ductile rau metalworking.

Tsis tas li ntawd, zirconium nyob hauv qhov xwm txheej li cas?

Zirconium yog qhov tseem ceeb tau los ntawm zirconium dioxide (baddeleyite) thiab zircon. Cov minerals kuj hnyav heev pom nyob rau hauv placer deposits thiab cua-workedsands, thiab yog mined nyob rau hauv Australia, South Africa, lub teb chaws USA, Russia thiab Brazil.

Ib tug kuj yuav nug, dab tsi hlau yog zirconium? Zirconium yog ib qho tshuaj lom neeg nrog atomicnumber 40, nyob rau hauv pawg 4 los ntawm daim ntawv qhia lub caij nyoog. Zr . Nws yog ib qho nyuaj hlau , resistant tocorrosion thiab zoo ib yam li hlau.

Ua li no, ntau npaum li cas zirconium?

Nws qhov kev nplua nuj yog kwv yees li 150 txog 230 qhov chaw permillion. Qhov ntawd tso nws qis dua cov pa roj carbon thiab sulfur ntawm cov ntsiab lus tshwm sim hauv ntiaj teb lub pob zeb. Qhov ob feem ntau feem ntau ores ntawm zirconium yog zircon , los yog zirconium silicate (ZrSiO 4); thiab baddeleyite, los yog zirconia los yog zirconium oxide (ZrO 2).

Vim li cas nws thiaj hu ua zirconium?
