Silicon carbide ceramics sintering process - vacfurnace

During the sintering process,ultra-fine silicon carbide particles form the 5-8μm silicon carbide crystal,which density is up to 97% or more and corrosion resistance is better than the sintered SiC.For the pressureless sintering, the billet of SiC is easily to make various shapes and bending and processing for more complex shape of products....<<more>>

Solid-state pressureless sintering of silicon carbide below

To date, solid-state pressureless sintering of silicon carbide powder requires sintering aids and high sintering temperature (>2100 °C) in order to achieve high sintered density (>95% T.D.). Two-step sintering (TSS) method can allow to set sintering temperature lower than that conventionally required....<<more>>
