Controlled process of liquid-phase sintering due to low-fusible melt forming

摘要

The article presents the analysis results of known state-transition diagrams of two- and three-component systems. Triple aluminosilicate and silicate systems have been investigated. Considering two-component systems the CaO ones have been analysed. Oxides, providing binary and ternary low-fusible eutectic are defined. Fluxing power of fluxing oxide in aluminosilicate systems, including argillous raw material is determined. Compositions in three-component silicate system are defined, providing the formation of low-fusible melt at less than 500 °C, that is 200°C lower than low-fusible clay. The results are used for controlled process of liquid-phase sintering: ceramic material production; composition development of raw batches, which neutralize harmful influence of carbonated impurities.
