Nkag siab txog nws cov yam ntxwv yog qhov tseem ceeb rau kev ua tiav kev ua tiav thoob plaws ntau hom kev lag luam.

To taub High Purity Silicon Carbide Powder

High purity silicon carbide hmoov, feem ntau hu ua SiC hmoov, yog ib daim ntawv crystalline ntawm silicon carbide nrog tsawg impurities. Qhov siab purity no yog qhov tseem ceeb rau nws qhov kev ua tau zoo hauv kev thov kev thov. Qib purity feem ntau yog qhia raws li feem pua ​​​​ntawm SiC cov ntsiab lus, nrog cov feem pua ​​​​siab dua qhia tias tsis muaj impurities tsawg. Cov hmoov cov khoom, xws li particle loj tis, morphology, thiab cheeb tsam saum npoo, sib txawv heev nyob ntawm txoj kev tsim. Cov khoom no ncaj qha cuam tshuam nws cov ntawv thov zaum kawg.

Cov txheej txheem ntau lawm ntawm High Purity Silicon Carbide Hmoov

Muaj ntau txoj kev siv rau kev tsim khoom siab purity silicon carbide hmoov. Cov feem ntau muaj xws li:

Txheej txheem Acheson

Cov txheej txheem Acheson yog ib txoj kev classic uas muaj cov tshuaj tiv thaiv kub ntawm silica (SiO₂) thiab carbon (C) nyob rau hauv lub cub hluav taws xob. Cov txheej txheem no yields SiC crystals ntawm qhov ntau thiab tsawg thiab cov duab. Thaum tus nqi pheej yig, nws tsim cov hmoov nrog kev sib piv qis purity piv rau lwm txoj kev.

Chemical Vapor Deposition (CVD)

CVD yog ib txoj kev siv dav rau kev tsim khoom siab purity silicon carbide hmoov nrog tswj particle loj thiab morphology. Gaseous precursors, xws li silane (SiH₄) thiab methane (CH₄), react ntawm qhov kub thiab txias los tsim SiC hais. Txoj kev no tso cai rau kev tswj xyuas meej ntawm cov hmoov cov yam ntxwv, ua rau nws zoo tagnrho rau kev siv tshwj xeeb. CVD kuj ua rau cov impurities tsawg dua li cov txheej txheem Acheson.

Lwm Txoj Kev

Lwm txoj hauv kev, xws li sol-gel synthesis thiab txo qis carbothermal, kuj tau ua haujlwm los ua kom muaj siab dawb huv SiC. Cov txheej txheem no muab cov txiaj ntsig tshwj xeeb nyob ntawm qhov kev xav tau tshwj xeeb rau qhov loj me, cov duab, thiab purity.

Daim ntawv thov ntawm High Purity Silicon Carbide Powder

Cov khoom tshwj xeeb ntawm siab purity silicon carbide hmoov ua kom nws haum rau ntau yam kev siv, suav nrog:

Kev lag luam semiconductor

Hauv kev lag luam semiconductor, SiC yog siv los tsim cov substrates rau cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob siab. Lub siab thermal conductivity thiab dav bandgap ntawm SiC ua rau kev tsim kho ntawm cov khoom siv hluav taws xob zoo dua thiab txhim khu kev qha.

Abrasives

Vim nws hardness thiab siab thermal stability, siab purity silicon carbide hmoov pom kev siv dav hauv cov cuab yeej txiav, sib tsoo lub log, thiab polishing compounds. Nws superior txiav peev xwm piv rau lwm yam abrasives ua rau nws nyiam xaiv nyob rau hauv ntau yam kev lag luam txheej txheem.

Refractories

SiC lub siab melting point thiab tshuaj inertness pab rau nws siv nyob rau hauv refractories, cov ntaub ntawv uas muaj peev xwm tiv taus kub heev. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev siv xws li metallurgical furnaces thiab high-temperature reactors.

Ceramics thiab Composites

High purity silicon carbide hmoov yog ib qho tseem ceeb ntawm cov khoom siv ceramics thiab cov khoom sib xyaw ua ke, qiv siab zog, hardness thiab hnav tsis kam rau cov khoom kawg. Qhov no pab txhawb rau ntau yam kev siv xws li armor plating thiab industrial Cheebtsam.
