Effect of MgO Additive on Microstructure of Al₂O₃

Abstract

Abstract. In this work, the consolidation of different alumina particles via sintering process was conducted to the compacted alumina pellets. This consolidation was also assisted with the sintering aid, MgO to densify the final ceramic structure. Comparison between the influence of additive to the different particles size of compacted alumina by observing the microstructure and physical properties was conducted. The value physical properties and microstructure clearly show that for both particle size of alumina, MgO additive can increase the density value and improve microstructure properties.

Effects of TiO2 addition on the phase, mechanical properties, and microstructure of zirconia-toughened alumina ceramic composite

“…In this pursuit of improving toughness, Al 2 O 3 based materials are often used as the benchmark due to its abundance, relative cheapness and excellent mechanical properties [9][10][11]. The introduction of the yttria stabilized zirconia (YSZ) toughening agent further increased the toughness of the zirconia toughened alumina (ZTA) ceramic composite [12].…”

Effect of Rice Husk on Fired Ceramic Shell Strength

“…2 [2, 23]. The diffusion mechanism is commonly achieved near melting temperature of that particular ceramic in order to ensure the diffusion of loose particles to occurs [24]. The consolidation process of ceramic body during the firing stage in which bonding and growth of necks in between the particles binds the particles strongly that would increase the strength of the sintered body [2, 4].…”

The Effect of Polyethelene Glycol on The Performance of Polysulfone Membrane Blend with Silica From Rice Husk

“…12 Theoretically, increase in MW of PEG, the pore number as well as pore size in membranes will increase while also membranes with PEG at higher MW have higher permeation water flux (PWF) and higher hydraulic permeability due to higher porosity. [14][15][16] However, Arthanareeswaran et. al, reported that by increasing PEG MW enhance the viscosity in casting solution.…”
