Cov khoom siv
Boron yog cov khoom siv raw khoom siv dav siv hauv kev tsim cov borax, boric acid thiab boron compounds thiab elemental boron, yog cov khoom siv tseem ceeb hauv metallurgy, cov ntaub ntawv hauv tsev, tshuab, khoom siv hluav taws xob, tshuaj lom neeg kev lag luam, lub teeb ntaub plaub, nuclear. kev lag luam, tshuaj, ua liaj ua teb thiab lwm yam departments. Tam sim no, muaj ntau dua 300 kev siv boron, ntawm cov iav kev lag luam, ceramic kev lag luam, cov tshuaj ntxuav tes thiab cov chiv ua liaj ua teb yog cov khoom siv tseem ceeb ntawm boron, suav txog li 3/4 ntawm lub ntiaj teb boron noj. Txawm hais tias Tuam Tshoj cov khoom siv pob zeb boron muaj nplua nuj, tab sis boron cov khoom lag luam tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim kho kev lag luam hauv tsev, hauv xyoo 2007, cov khoom siv borax hauv tsev yog kwv yees li 400,000 tons, cov khoom lag luam boron txawv teb chaws muaj 648,700 tons, ntau ntawm kev vam khom rau kev xa khoom, yog li ntawd. nkag siab txog lub ntiaj teb boron ntxhia khoom lag luam qhov teeb meem tseem ceeb heev.
Elemental boron yog siv los ua tus neeg saib xyuas zoo, oxidizing tus neeg sawv cev, tus neeg sawv cev brominating, cov khoom sib xyaw ntawm cov organic synthesis, insulator ntawm high voltage thiab high zaus hluav taws xob thiab plasma arc, kis tau tus mob qhov rai ntawm radar, thiab lwm yam.
