Dub Silicon Carbide Micropowder (Black Silicon Carbide Micropowder) yog ib hom micron-loj hmoov cov khoom ua los ntawm silicon (Si) thiab carbon (C) reacted ntawm qhov kub thiab txias, nrog cov xim ntawm grey tsaus rau dub, siab hardness, puas-resistant. , siab thermal conductivity, uas muaj ntau yam kev siv nyob rau hauv cov teb ntawm abrasive, refractory, electronics, photovoltaic, thiab lwm yam.
dub silicon carbide hmoov lub ntsiab nta
1. Siab hardness
Lub hardness ntawm dub silicon carbide micropowder yog ze rau pob zeb diamond, nrog ib tug Mohs hardness txog 9.2, ua rau nws ib tug zoo tagnrho super-hard abrasive. Nws yog feem ntau siv rau hauv kev tsim khoom ntawm ntau yam abrasives thiab polishing cov ntaub ntawv, thiab yog tsim rau kev ua cov ntaub ntawv siab hardness xws li ceramics, iav, gemstones, thiab cemented carbide.
2. Zoo abrasion tsis kam
Black silicon carbide micropowder muaj kev puas tsuaj zoo heev thiab tshwj xeeb tshaj yog siv rau hauv qhov chaw muaj kev puas tsuaj. Nws yog dav siv nyob rau hauv cov khoom xws li sib tsoo thiab polishing, txheej cov ntaub ntawv thiab sib tsoo log los txhim kho cov hnav tsis kam thiab kev pab cuam lub neej ntawm cov ntaub ntawv.
3. Zoo heev thermal conductivity
Vim lub siab thermal conductivity ntawm dub silicon carbide, nws tuav zoo thermal conductivity nyob rau hauv high-temperature ib puag ncig. Nws yog feem ntau siv hauv cov khoom siv hluav taws xob thiab cov khoom siv kub kub uas xav tau cov khoom siv hluav taws xob, xws li thermal conductive heat sinks, ceramic substrates thiab cov ntaub ntawv thermoelectric.
4. Qhov kub thiab txias tsis kam thiab oxidation tsis kam
Dub silicon carbide micropowder qhia tau hais tias kev ruaj ntseg zoo heev ntawm qhov kub thiab txias, nrog lub melting point siab txog 2700 degree, thiab kuj muaj zog oxidation tsis kam. Nws yog feem ntau siv nyob rau hauv ob sab phlu ntawm high-temperature furnaces, refractory cov ntaub ntawv, thiab nyob rau hauv lub cubes thiab kilns nyob rau hauv lub smelting kev lag luam.
5. Tshuaj Stability
Black silicon carbide micropowder qhia tau hais tias muaj tshuaj lom neeg ruaj khov nyob rau hauv ob qho tib si acid thiab alkali, thiab muaj peev xwm ua kom nws cov khoom ruaj khov nyob rau hauv qhov hnyav hnyav. Yog li ntawd, nws kuj tuaj yeem siv rau hauv cov khoom siv thiab cov thawv ntim khoom uas siv cov khoom corrosive.
6. Photovoltaic thiab hluav taws xob siv
Hauv thaj chaw ntawm photovoltaics, dub silicon carbide micropowder tuaj yeem siv rau hauv kev tsim cov cuab yeej txiav rau polysilicon wafers, nrog rau cov txheej txheem polishing ntawm cov khoom photovoltaic. Hauv kev lag luam hluav taws xob, dub silicon carbide micropowder kuj yog siv los ua cov khoom siv rau cov khoom siv hluav taws xob thiab cov khoom siv kub thiab cov khoom siv hluav taws xob siab vim nws cov khoom semiconductor.
dub silicon carbide hmoov siv lub ntsiab
- Abrasives: Tsim cov tawv tawv abrasives xws li kev sib tsoo log, txiav hniav thiab polishing hmoov;
- Refractories: rau high-temperature kiln rooj tog, refractory cib, crucibles thiab furnace tubes;
- Cov khoom siv hluav taws xob hluav taws xob hluav taws xob: rau cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob semiconductor;
- Photovoltaic txiav thiab polishing: txiav, nto polishing ntawm polysilicon wafers;
- Ceramics thiab composite cov ntaub ntawv: siv los ua hnav-resistant thiab kub-resistant ceramics thiab composite cov ntaub ntawv.
Black silicon carbide micropowder tau dhau los ua cov khoom siv superhard tsis tseem ceeb hauv kev lag luam niaj hnub no vim nws cov tawv tawv siab, hnav tsis kam thiab thermal conductivity, thiab tsim nyog rau ntau yam kev thov scenarios nrog kev ua haujlwm siab thiab tshwj xeeb ib puag ncig.
