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?
Lub ntsiab zirconium yog npe tom qab lub themineral uas nws tau pom, zircon . Lo lus “ zircon " tej zaum tau muab los ntawm Persian lo lus zargun, uas txhais tau tias "xim kub." Ib txhia zircon Crystals muaj xim kub.

Yuav ua li cas koj paub yog tias nws yog Codominance los yog tsis tiav dominance?
Nyob rau hauv tsis tiav dominance ib tug heterozygous ib tug blends ob yam. Nrog codominance koj yuav pom ob qho tag nrho alleles qhia lawv cov teebmeem tab sis tsis sib xyaw whereas nrog tsis tiav dominance koj pom ob qho tag nrho alleles tab sis lawv tau muab sib xyaw
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas yog cov structural units uas ua ionic compounds thiab yuav ua li cas lawv hu ua?
Rau binary ionic compounds (ionic compounds uas muaj tsuas yog ob hom ntawm cov ntsiab lus), cov tebchaw muaj npe los ntawm kev sau lub npe ntawm cov cation ua ntej tom qab lub npe ntawm anion. Piv txwv li, KCl, ib qho ionic compound uas muaj K + thiab Cl-ions, yog lub npe hu ua potassium chloride
Yuav ua li cas koj qhia yog hais tias lub pob zeb yog igneous metamorphic los yog sedimentary?
Tshawb xyuas koj lub pob zeb kom pom cov cim pom pom. Igneous pob zeb yog tuab heev thiab nyuaj. Cov pob zeb metamorphic kuj tseem tuaj yeem muaj lub ntsej muag iav. Sedimentary pob zeb uas tsis muaj nplej yuav zoo li cov av nkos qhuav. Cov pob zeb sedimentary uas tsis muaj nplej kuj zoo li mos, asthey feem ntau tuaj yeem khawb tau yooj yim nrog tus ntiv tes
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
