The physical and chemical properties of fly ash influence the sintering temperature, which is usually ranges between 1000 and 1300 °C. When fly ash pellets are sintered at temperatures below 1000 °C, the fly ash particles become loosely bonded together, resulting in a weaker matrix and increased absorption.
