Porous MgO-based ceramics synthesized by the volume expansion effect: Designing and performance

Journal of Materials Research and Technology, Journal Year: 2024, Volume and Issue: 28, P. 4370 - 4381

High-quality porous ceramics are extremely attractive in terms of energy conservation and consumption reduction, thus one the research hotspots pursued recent years. For this purpose, MgO-based with outstanding thermal shock resistance insulation performance were designed prepared by using direct firing method introducing alumina different paticle sizes as additives. The results reveal that in-situ formed MgAl2O4 phase additives simultaneously improves apparent porosity, insulation, ceramics. Specifically, increase porosity can be attributed to volume expansion effect phase, so industrial larger particle size is more effective (20 wt% addition: from 43.5 % 55.4 %, conductivity 0.977 0.389 W m−1 K−1 at 800 °C); moreover, enhancement ascribed residual stress caused particles, micron smaller efficient (10 strength ratio 93.48 65.13 %–113.92 94.47 after five air-quenching). Therefore, work demonstrates a novel synthetic strategy for great potential field high-temperature insulation.

Early age structural build-up and pore stability in raw foam at ambient conditions: Implications for the final properties of glass-ceramic foam

Construction and Building Materials, Journal Year: 2024, Volume and Issue: 428, P. 136369 - 136369

Published: April 25, 2024

Alkali activation followed by foaming techniques is an effective method for glass-ceramic foam development where early-age reactions in the alkali-activated precursors and reaction happen simultaneously. Therefore, this early stage must be clearly understood to control pore characteristic foams. However, correlations between structural build-up stability their consequences on final properties of sintered foams have not been investigated. This research aims examine relationship. 80–95 wt % waste glass 5–20 slag were used as research. Using alkali combined technique, raw was developed hardened at ambient conditions. The reactivity binder foamed suspension studied through rheological parameter chemical structure analysis over hardening period. During process, percolation effect gels contribute network formation suspension. As time increases, matrix strengthens, pores stabilise crosslinking gels. After hardening, evaluated correlated with fresh foam. study demonstrates that interaction during process controls stability, connected volume, strength By understanding these parameters, can controlled effectively.
