Sintering: Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it. When the temperature inside the kiln reaches about 1300°C (the eutectic melting point of aluminate, ferrite and silicate), clinker flux is produced.
