Silicon Carbide rau qhov kub thiab txias
Silicon carbide (SiC) yog qhov paub zoo rau nws qhov tshwj xeeb ntawm qhov kub thiab txias, ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov uas yuav tsum tau ua haujlwm kub.

Kev piav qhia
Qhov zoo ntawm silicon carbide yog nws lub peev xwm los tswj nws cov thermal conductivity txawm nyob rau qhov kub siab.
Tsis zoo li lwm cov ntaub ntawv, SiC tsis muaj kev poob qis hauv thermal conductivity thaum kub nce. Cov yam ntxwv no ua rau nws haum rau cov ntawv thov uas ua haujlwm ntawm qhov kub thiab txias, xws li aerospace, automotive engine Cheebtsam, thiab high-temperature electronic devices.

Nov yog qee cov ntsiab lus tseem ceeb hais txog silicon carbide qhov kub thiab txias:
- High Melting Point: Silicon carbide muaj qhov siab melting point ntawm ib ncig ntawm 2700 degree (4892 degree F). Qhov siab melting point no tso cai rau SiC khaws nws cov qauv kev ncaj ncees thiab txhua yam khoom txawm tias qhov kub thiab txias, qhov twg lwm cov ntaub ntawv yuav degrade los yog yaj.
- Thermal conductivity: SiC nthuav tawm cov thermal conductivity zoo heev, uas yog ib qho tseem ceeb rau dissipating tshav kub generated nyob rau hauv high-kub ib puag ncig.
- Thermal Expansion: Silicon carbide muaj cov coefficient tsawg ntawm thermal expansion piv rau lwm cov ntaub ntawv. Qhov no txhais tau hais tias SiC nthuav tawm qhov hloov pauv me me nrog qhov hloov pauv kub.
- Oxidation Resistance: Silicon carbide tsim cov txheej txheem oxide tiv thaiv ntawm nws qhov chaw thaum raug oxygen ntawm qhov kub thiab txias. Cov txheej txheej oxide no ua rau muaj kev thaiv, tiv thaiv cov khoom siv SiC los ntawm kev oxidation ntxiv.
- Dav Kub Kub: Silicon carbide tuaj yeem ua haujlwm nyob rau hauv ntau qhov kub thiab txias, los ntawm qhov kub thiab txias mus txog 1600 degree (2912 degree F) hauv huab cua thiab txawm tias kub dua hauv inert lossis txo cov cua.
- Thermally Stable Electrical Properties: Silicon carbide nthuav tawm cov khoom hluav taws xob ruaj khov tshaj qhov kub thiab txias. Qhov no suav nrog kev tswj hwm nws qhov siab tawg qhov hluav taws xob thiab hluav taws xob tsis zoo ntawm qhov kub siab.
Vim nws qhov tshwj xeeb kub ruaj khov, silicon carbide pom cov ntawv thov hauv kev lag luam uas qhov kub-kub kuj tseem ceeb heev.
Cov no suav nrog aerospace thiab aviation, automotive, tsim hluav taws xob thiab kev faib tawm, cov khoom cua sov, cov ntsuas kub siab, thiab ntau yam kev ua haujlwm kub.
