Kev txhim kho keeb kwm ntawm silicon carbide
Silicon carbide yog ib hom carbide nrhiav pom hauv chav kuaj los ntawm American Acheson thaum lub sij hawm electrofusion pob zeb diamond sim nyob rau hauv 1891. Thaum lub sij hawm ntawd, nws tau yuam kev rau ib tug sib tov ntawm pob zeb diamond, yog li ntawd nws tau hu ua emery. Nws tau tshawb fawb los ntawm Acheson xyoo 1893. Txoj kev lag luam ntawm smelting silicon carbide, uas feem ntau hu ua Acheson rauv, tau siv los txog rau tam sim no. Lub qhov cub ua haujlwm nrog cov khoom siv carbonaceous raws li lub tshuab ua kom sov yog lub zog kom sov qhov sib xyaw ntawm quartz SiO2 thiab carbon los tsim silicon carbide.
Muaj ntau qhov xwm txheej txog silicon carbide:
Xyoo 1905, silicon carbide tau pom thawj zaug hauv lub meteorite.
Xyoo 1907, thawj silicon carbide siv lead ua lub teeb-emitting diode tau yug los.
Xyoo 1955, qhov kev ua tiav loj hauv kev xav thiab thev naus laus zis, LELY tau npaj lub tswv yim ntawm kev loj hlob zoo carbonization, thiab txij li ntawd los siv SiC ua cov khoom siv hluav taws xob tseem ceeb.
Xyoo 1958, thawj World Silicon Carbide Conference tau muaj nyob rau hauv Boston rau kev sib pauv kev kawm.
Xyoo 1978, silicon carbide tau tshawb fawb los ntawm qub Soviet Union hauv xyoo 1960 thiab 1970s. Los ntawm 1978, cov nplej purification thiab txoj kev loj hlob ntawm"LELY txhim kho tshuab" tau txais thawj zaug.
Txij xyoo 1987 mus txog rau tam sim no, cov khoom siv silicon carbide tau tsim los ntawm kev tshawb fawb ntawm CREE, thiab cov neeg muag khoom tau pib muab cov khoom lag luam silicon carbide hauv paus.
