Piv nrog rau aluminium oxide, silicon carbide muab kev txiav nrawm dua thiab cov txiaj ntsig zoo dua ntawm cov ntaub ntawv tawv thiab tawv xws li iav thiab ceramics.

Daim ntawv thov Refractory

Silicon carbide kuj yog ib qho tseem ceeb ntawm cov khoom siv refractory.

• Rauv linings
• Kiln rooj tog
• Crucibles

Nws tiv thaiv thermal shock thiab oxidation tso cai rau lub neej ntev kev pab cuam piv rau ntau yam khoom siv refractory.

Semiconductor thiab Electronics

Silicon carbide tau dhau los ua qhov tseem ceeb hauv kev lag luam hluav taws xob vim nws cov khoom siv dav dav.

• Electric tsheb (EVs)
• Fais fab mov modules thiab inverter
• Cov tshuab hluav taws xob tauj dua tshiab

Piv rau cov pa roj carbon monoxide, SiC cov cuab yeej ua haujlwm ntawm qhov kub siab dua, qhov hluav taws xob, thiab kev ua tau zoo.
