Mechanism of melilite formation during a sintering process

Solid solutions of melilite were produced by industrial raw materials (phosphorous furnace slag, dolomitic limestone and clay) at temperatures till 1200 K. At this solid state reaction different processes are participating. From the formation rate at constant temperature different processes were recognized by graphical analysis and explained by a mechanism of melilite formation. Some different temperatures were used. The investigations are used to produce a new ceramic material on the base of melilite.
