Unlike traditional ceramics, however, advanced powders are not bonded … WebApr 12, 2024 · High temperature (>950 °C) may also lead to particle agglomeration and sintering of the OC [46,47]. Moreover, high temperature promotes the combustion reaction of the H 2 and oxygen carriers, resulting in a decrease in the proportion of the product of H 2. Overall, the experimental gasification temperature was set to 950 °C.

WebSintering is the heating of powder to fuse the particles into a solid material end product. The sintering temperature varies and needs to be high enough to cause fusion without melting the particles. Examples of some applications of sintering include creating technical ceramics and the fusion of metallic powders under high pressure conditions.
