 · Residual stevensite appears at 900 C while a potassium aluminium silicate phase, noted PAS, is formed during sintering up to 1100 C. The latter phase disappears after sintering at 1200 °C. Such behaviour concomitantly with the microstructure evolution of these samples is consistent with the potassium phase reaction to form a glassy phase that enhances the consolidation of relevant products.
