Lub evolution ntawm titanium smelting technology tau ib tug zoo kawg li txoj kev uas yog cim los ntawm cov tseem ceeb milestones nyob rau hauv metallurgy.
Titanium, ib qho tseem ceeb ntawm cov khoom siv hlau, pib pom tab sis siv tsis tau, pom qhov kev sib tw hauv xyoo 1910 thaum American chemist Hunter tau ua tiav 99.9% ntshiab titanium hlau siv txoj kev txo sodium. Txoj kev no, hu ua "Hunter txheej txheem," txawm tias txwv tsis pub tawm los, teeb tsa theem rau kev nce qib ntxiv.
Xyoo 1932, tus kws tshawb fawb Asmeskas Kroll tau ua tiav qhov tseem ceeb los ntawm kev siv cov calcium uas muaj txiaj ntsig los txo cov titanium tetrachloride ntawm qhov kub thiab txias, paving txoj hauv kev rau kev lag luam titanium ntau lawm. Tom qab ntawd, Kroll tau kho cov txheej txheem los ntawm kev hloov cov calcium nrog magnesium, kev hloov kho tam sim no hu ua "Kroll txheej txheem," uas tseem yog ib qho tseem ceeb rau niaj hnub titanium ntau lawm.
Lub sijhawm tseem ceeb tuaj txog xyoo 1948 thaum Lub Tuam Txhab DuPont hauv Teb Chaws Asmeskas tau qhia txog magnesium txo-nqus distillation txoj kev rau loj-tsim titanium, qhia txog qhov pib ntawm kev lag luam titanium. Cov txheej txheem no suav nrog kev hloov titanium dioxide mus rau titanium tetrachloride los ntawm cov tshuaj tiv thaiv, txo cov tetrachloride nrog hlau magnesium kom tau sponge titanium, thiab thaum kawg purifying sponge titanium los ntawm lub tshuab nqus tsev distillation kom tau cov ntshiab titanium.
Lub zog-intensive xwm ntawm titanium ntau lawm, yuav tsum tau high-temperature ua hauj lwm, pab txhawb rau cov hlau tus nqi hwm. Tam sim no, magnesium txo qis-nqus distillation txoj kev, paub txog nws superior zoo thiab kev nyab xeeb kev ua hauj lwm, yog dav saws thoob ntiaj teb rau daim txhuam cev titanium ntau lawm. Txoj kev taug kev los ntawm titanium qhov kev tshawb pom mus rau kev tsim cov ntshiab titanium hla dhau ib puas xyoo, thiab niaj hnub no, titanium pom cov ntawv thov thoob plaws ntau hom kev lag luam vim nws cov khoom tshwj xeeb thiab kev ua haujlwm zoo.
