Development of porous mullite and mullite-Al2O3 composite for microfiltration membrane applications

Freeze-casting applied to ceramic materials: a short review of the influence of processing parameters

“…Fukushima's research group has conducted several studies [2,[14][15][16][17][18][19][20][21] focused on the manufacture of high porosity materials through freeze-casting. In 2018, Tang et al [22][23][24][25][26] also turned their researches to the method, and in 2019, several authors [27][28][29][30][31][32][33][34] reported studies involving freeze-casting to obtain materials with high porosity and morphological pore control. Therefore, this scientific field is in continuous growth, and studies that improve the method are published even today.…”

Microstructural characteristics, properties, synthesis and applications of mullite: a review

“…It has an orthorhombic structure, characterized by the presence of octahedral chains of AlO 6 located at the vertices and in the center of the unit cell, with edges aligned in parallel along the 'c' crystallographic axis. The AlO 6 chains are interconnected by double tetrahedral chains of aluminum-oxygen and/or silicon-oxygen (AlO 4 /SiO 4 ), also aligned in parallel with the c axis [15,[17][18][19]. Mullite has a crystalline structure closely related to that of sillimanite (Al 2 O 3 .SiO 2 ) and both have silicon and aluminum atoms located in tetrahedral sites.…”

Photocatalytic Degradation of Rhodamine B by TiO2 Pillared Illite/Smectite (Ti/(I/S)) under Visible‐Light Irradiation

“…And these clay minerals have the characteristics of exchangeable cations and expandability. [ 9–11 ] Reflecting Al, [ 12–14 ] Zn, [ 15–17 ] Fe, [ 18–20 ] Ti [ 21–23 ] as the pillaring agent precursor into the clay layer, and converting it into oxide by calcination, the specific surface area, adsorption and interlayer distance of the photocatalyst can be improved, which is conducive to light generate electron‐hole transport and separation and increase the active site.
