Lithium aluminosilicate was fabricated by conventional and non-conventional sintering:microwave and spark plasma sintering, from 1200 to 1300 ºC. A considerable difference in densification, microstructure, coefficient of thermal expansion behavior and hardness and Young's modulus was observed. Microwave technology made possible to obtain fully dense glass-free lithium aluminosilicate bulk material (>99%) with near-zero and controlled coefficient of thermal expansion and relatively high mechanical properties 1 (7.1 GPa of hardness and 110 GPa of Young's modulus) compared to the other two processes. It is believed that the heating mode and effective particle packing by microwave sintering are responsible to improve these properties.

Abstract3 mol% Y 2 O 3 -stabilized zirconia nanopowders were fabricated using various sintering techniques; conventional sintering (CS) and non-conventional sintering such as microwave (MW) and pulsed electric current-assisted-sintering (PECS) at 1300 ºC and 1400 ºC. A considerable difference in the densification behaviour between conventional and non-conventional sintered specimens was observed. The MW materials attain a 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 2 bulk density 99.4% theoretical density (t.d.) at 1300 ºC, while the CS materials attain only 92.5% t.d. and PECS 98.7% t.d. Detailed microstructural evaluation indicated that a low temperature densification leading to finer grain sizes (135 nm) could be achieved by PECS followed by MW with an average sintered grain size of 188 nm and CS 225 nm. It is believed that the high heating rate and effective particle packing are responsible for the improvements in these properties. *Manuscript Click here to view linked References

“…[16][17][18][19][20][21] In all cases, the powders were directly heated without any specific preparation. In Kim et al papers,19,20 transparent PCA was obtained by direct SPS-heating of the as-received sub-micron grained corundum powder without any pre-treatment or additives, whereas Jiang et al 21 produced an optically transparent PCA in IR spectrum, with 0.2 wt% MgO added to the initial corundum powder.…”
