Raws li Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Lag Luam Kev Lag Luam ntawm Tuam Tshoj lub siab purity alumina kev lag luam (2021 Edition) tso tawm los ntawm Limu cov ntaub ntawv kev sab laj, siab purity alumina muaj qhov zoo ntawm siab hardness, siab zog thiab kub tsis kam, thiab yog dav siv hauv electronics, semiconductor thiab lwm yam lag luam.High purity alumina yog tsuas yog siv los ua ceramic substrates rau integrated circuits thiab automotive sensors.Nws yog ib qho ntawm cov khoom siv tshaj plaws.
Nyob rau hauv Suav teb, lub peev xwm nominal ntawm ntau lub tuam txhab ua lag luam uas tsim cov alumina high-purity yog nyob rau hauv kev txiav txim ntawm ntau txhiab tons.Qhov tseeb, feem ntau ntawm lawv yog cov concentrated hauv cov khw muag khoom qis xws li phosphor.Txawm li cas los xij, purity ntawm qee cov tuam txhab hauv tsev tau mus txog saum 4n5, thiab tsis muaj qhov sib txawv nrog cov tuam txhab ua lag luam txawv teb chaws nyob rau hauv cov nqe lus ntawm purity.Daim ntawv thov nyob rau hauv cov kev taw qhia ntawm sapphire substrate yuav paub ntshuam hloov.Txawm li cas los xij, hais txog qhov loj me, cov lag luam txawv teb chaws tuaj yeem ua tiav qis dua 30nm (nm), thiab feem ntau cov lag luam hauv tsev tseem muaj qhov sib txawv.Yog li ntawd, tam sim no, alumina rau lithium roj teeb diaphragm yog muab los ntawm Sumitomo tshuaj thiab lwm yam txawv teb chaws manufacturers.
Nyob rau hauv daim ntawv thov sapphire teb, domestic high-purity alumina ntau lawm tuam txhab uas muag muaj cuab kev ua tau zoo tus nqi zoo thiab nyob ze rau cov neeg muas zaub geographically, uas yuav undoubtedly muaj zoo zoo.Nyob rau tib lub sij hawm, nyob rau hauv lub teb ntawm high-end high-purity alumina, nrog rau kev vam meej ntawm domestic tuam txhab uas muag 'technology, domestic tuam txhab uas muag nrog ua technology thiab siab nqi kev ua tau zoo yuav sai sai paub ntshuam hloov, thiab nkag mus rau lub thoob ntiaj teb kev lag luam export siab. - purity alumina.
Vim lub monopoly ntawm high-end ntshuam thiab saturation ntawm low-end nyob rau hauv lub domestic high-purity alumina lag luam, nws yuav yog ib tug kev loj hlob qauv rau high-purity alumina los hloov imports thiab ua tau raws li qhov kev thov ntawm lub domestic kev ua lag luam.
Txoj kev loj hlob ntawm high purity alumina kev lag luam nyob rau hauv Tuam Tshoj yog kuj lig thiab tseem nyob rau hauv nws cov me nyuam mos.Tam sim no, cov txheej txheem tseem ceeb yog txhim kho Bayer txheej txheem.Nyob rau theem no, cov khoom siv hauv tsev feem ntau yog 4N alumina, thiab muaj ob peb lub tuam txhab lag luam uas tuaj yeem tsim cov khoom 5N.Nyob rau hauv 2019, cov zis ntawm Tuam Tshoj lub high-purity alumina kev lag luam yog 7600 tons, qhov kev thov yog 15700 tons, thiab net ntshuam mus txog 8100 tons.Nyob rau hauv 2020, cov zis ntawm Tuam Tshoj lub high-purity alumina kev lag luam yog 8280 tons, qhov kev thov yog 17035 tons, thiab net ntshuam mus txog 8750 tons.
Shandong Zhanchi Tshiab Khoom Co., Ltd (Shanghai Chenxu Trading Co., Ltd) tsim 5N 99.999 siab purity alumina, nws puv qhov sib txawv ntawm domestic technology thiab lov lub monopoly ntawm txawv teb chaws technology.
