文摘

Initial ash sintering temperatures were detected by cold compression strength tests. Three different ashes were investigated at oxidizing, inert, and reducing conditions. Sintering relevant phases were found by SEM/EDX, high temperature XRD, and TG-DSC. Silicates, iron-aluminum-oxides, carbonation, and iron sulfide melts induce sintering. Sintering can be connected with melt formation or solid phase sintering.
