Zirconium Production Upstream Thiab Downstream Industry Chain
Jan 31, 2024
Zirconium cov khoom muaj nplua nuj thiab ntau haiv neeg, feem ntau cov ntxhia hauv daim ntawv ntawm zircon xuab zeb, tom qab caustic soda, ntxuav thiab lwm yam kev kho mob, tuaj yeem tsim zirconium silicate thiab zirconium chloride thiab lwm yam khoom tseem ceeb; txuas ntxiv rau calcine, chlorination, txo qis tuaj yeem ua rau zirconium dioxide, qib qib zirconium daim txhuam cev, thiab lwm yam khoom; Yog hais tias theem ntawm purification, kev sib cais tshuab mus txog ib tug tej theem, nws yuav ua tau rau hauv ib tug nuclear zog-qib zirconium daim txhuam cev.
Zirconium muaj ntau yam kev siv, feem ntau nyob rau hauv daim ntawv ntawm zirconium silicate, zirconium oxide siv nyob rau hauv ceramics, refractory cov ntaub ntawv thiab lwm yam teb. Tsuas yog 3-4% ntawm zirconium ore tau ua tiav rau hauv cov hlau zirconium (los yog zirconium daim txhuam cev), uas yog ntxiv ua tiav rau ntau yam ntaub ntawv zirconium. Zirconium hlau muaj cov khoom siv hluav taws xob zoo heev vim nws qhov me me thermal neutron absorption cross-section, thiab nuclear-qib zirconium yog siv los ua cov khoom siv rau nuclear-powered aircraft carriers, nuclear submarines thiab pej xeem lub zog reactors, thiab raws li ib tug casing rau uranium roj ntsiab. . Nuclear-qib zirconium tuaj yeem suav tias yog cov hlau tseem ceeb ntawm lub tebchaws tseem ceeb thiab muaj feem cuam tshuam nrog kev txhim kho ntawm kev lag luam nuclear.
Raws li cov hlau reactive, zirconium tsim cov oxide zaj duab xis ntawm chav tsev kub, uas muab zirconium thiab nws cov alloys zoo heev corrosion kuj. Nyob rau tib lub sijhawm zirconium muaj cov cuab yeej zoo thiab cov khoom siv hluav taws xob hloov pauv, uas, ua ke nrog cov txiaj ntsig zoo, ua rau nws zoo heev corrosion resistant cov khoom siv rau niaj hnub no kev lag luam petrochemical.
Zirconium siv nyob rau hauv tshuaj lom neeg acid thiab alkali resistant khoom, tub rog thiab electronics kev lag luam yog hu ua industrial qib zirconium. Los ntawm qhov pom ntawm kev ua haujlwm nyuaj, qib thev naus laus zis thiab cov ntsiab lus thev naus laus zis, hlau zirconium thiab nws cov khoom siv hlau yog nyob rau sab saum toj ntawm kev lag luam saw.
