“…In the absence of fluid, reactions involving MAS phases are notoriously sluggish because the phases are so refractory, and thus often proceed via metastable intermediates; so with insufficient run durations, incompatible phase assemblages may be observed even when the temperatures are relatively high. For example, Shu et al (2002) and Menchi & Scian (2005) reported the joint appearance of sapphirine and cristobalite at temperatures between 1200°C and 1280°C in crystallizing cordierite ceramics. Conversely, crystallizing a mixture of cordierite + spinel with stoichiometry of sapphirine 2:2:1 at 900°C and 1.5 GPa, Schreyer (1967) initially obtained orthopyroxene + corundum + spinel in a 22 h long run, and only in longer runs did the mixture yield 40 % of sapphirine.…”

“…The results showed good sintering characteristics with improved mechanical properties at zirconia composition of 15 wt%. 14 The reports suggested that the cordierite matrix dispersed with fine zirconia (ZrO 2 ) increased the mechanical properties but affect the sinterability of the composites 15 and the dispersion of ZrO 2 particles as a second phase enhanced the mechanical properties of cordierite. 16 The present research work is focused on the synthesis of highly homogeneous cordierite and cordierite-zirconia (5-20 wt%) ceramic.…”

“…They find applications in many diverse areas [3]. Silicates are widely used as adsorbents of polysaccharides [4] and numerous ions such as lead or calcium [5], as potentiometric sensors of hydrogen ions [6], in production of ceramics [7] or for sorption of atmospheric CO 2 [8], to recover cerium from radioactive waste materials and to adsorb Nd 3+ ions [9], as bioactive materials [10,11], as microwave dielectric [12], etc. As a kind of biodegradable ceramic with good bioactivity, beta-CaSiO 3 has been widely used for preparation of beta-CaSiO 3 /biopolymer composite scaffolds and has been proved to be an effective additive to create bioactive composites [13][14][15].…”
