Dab tsi yog silicon carbide siv rau?

Silicon carbide (SiC)yog cov khoom siv ntau yam khoom siv nrog tshwj xeeb hardness, thermal stability, thiab tshuaj tsis kam. Nws siv ntau qhov kev lag luam vim yog cov khoom tshwj xeeb no. Nov yog cov ncauj lus kom ntxaws:

 

1. Abrasives

Sib tsoo lub log, cov ntawv xuab zeb, thiab cov cuab yeej txiav
SiC qhov nyuaj heev (ze rau pob zeb diamond) ua rau nws zoo tagnrho rau kev sib tsoo, polishing, thiab txiav hlau, ceramics, thiab pob zeb.

Lapping thiab finishing hmoovrau precision nto tiav hauv electronics thiab optics.

 

2. Refractories thiab High -Tsuas siv

Furnace linings, crucibles, thiab kiln rooj tog
SiC tiv taus qhov kub siab tshaj 1600℃thiab tiv thaiv thermal shock, ua rau nws zoo meej rau siab - qhov cub kub.

Cov khoom cua kub thiab cov burnersrau industrial kilns thiab cov khoom siv kho cua sov.

 

3. Ceramics

Advanced structural ceramicsrau hnav-cov khoom tiv taus, foob, thiab cov kabmob.

SiC ceramic Cheebtsamnyob rau hauv automotive brakes, clutches, thiab turbine hniav.

 

4. metallurgy

Deoxidizer thiab alloying additive nyob rau hauv steelmaking
SiC yog siv los ua ib qhodeoxidizer, carbon qhov chaw, los yog inoculantnyob rau hauv cam khwb cia hlau thiab hlau, txhim kho lub zog thiab nto tiav.

Cov ntawv thov kev pabrau pwm thiab cores, vim muaj thermal conductivity thiab tshuaj stability.

 

5. Electronics thiab Semiconductors

Lub zog hluav taws xob: SiC yog qhov dav -bandgap semiconductor haum rauhigh-voltage, siab-kub, thiab siab- cov khoom siv zaus.

Diodes, MOSFETs, thiab Schottky li: Siv hauv tsheb fais fab, hnub ci inverters, thiab cov khoom siv hluav taws xob hloov hluav taws xob.

LED substratesrau lub teeb -emitting li.

 

6. Automotive Applications

Nres discs thiab clutch phaj: SiC ceramics tiv taus hnav thiab kub.

Cav Cheebtsam: Turbocharger rotors thiab lwm yam uas yuav tsum tau thermal kuj.

 

7. Aerospace thiab Defense

Ablative cov ntaub ntawv, armor, thiab tshav kub shields
SiC composites yog siv nyob rau hauv spacecraft, missiles, thiab aircraft rau lawvsiab zog-rau- hnyav pivthiab kub tsis kam.

 

8. Kev lim dej thiab kev siv ib puag ncig

SiC porous ceramicsraumolten hlau lim, gas filtration, thiab chemical filtration systems.

Cov tshuaj tiv thaiv siab tso cai siv rau hauv qhov chaw corrosive.

 

Cov Khoom Tseem Ceeb Tsav Nws Siv

Hardness heev (Mohs ~ 9-9.5)

High thermal conductivity

Chemical inertness thiab corrosion kuj

Dav bandgap rau siab -kub hluav taws xob

Tsawg thermal expansion thiab zoo heev thermal shock kuj

 

Hauv luv luv,silicon carbide yog siv nyob qhov twg hardness, siab -kub stability, hnav tsis kam, los yog chemical durability yog xav tau, los ntawm steelmaking thiab abrasives mus rau advanced electronics thiab aerospace.
