“…Related to this work, Harabi and co-workers [37][38][39][40][41][42][43][44][45][46][47][48] have investigated most of the ceramic support fabrication from kaolin and reported mechanical strength value and porosity. Based on the Table 3 Gas permeation performance of kaolin ceramic support at different kaolin particle sizes and contents.…”

a b s t r a c tIn this study, low cost ceramic supports were prepared from kaolin via phase inversion technique with two kaolin particle sizes, which are 0.04-0.6 m (denoted as type A) and 10-15 m (denoted as type B), at different kaolin contents ranging from 14 to 39 wt.%, sintered at 1200 • C. The effect of kaolin particle sizes as well as kaolin contents on membrane structure, pore size distribution, porosity, mechanical strength, surface roughness and gas permeation of the support were investigated. The support was prepared using kaolin type A induced asymmetric structure by combining macroporous voids and sponge-like structure in the support with pore size of 0.38 m and 1.05 m, respectively, and exhibited ideal porosity (27.7%), great mechanical strength (98.9 MPa) and excellent gas permeation. Preliminary study shows that the kaolin ceramic support in this work is potential to gas separation application at lower cost.

“…Several materials are usually employed for the preparation of ceramics membranes, such as alumina, zirconia and titania. However, natural raw materials, such as kaolin (chemical structure: [57,58] are more and more used for preparing porous ceramics membranes [9][10][11][12][59][60][61][62][63][64][65][66][67][68] and it has been used in this work as a starting material.…”

The preparation and characterization of porous tubular ceramic composite microfiltration membranes, using kaolins and calcium carbonates, were reported. The porous gehlenite (2CaO·Al 2 O 3 ·SiO 2 ) and anorthite (CaO·Al 2 O 3 ·2SiO 2 ) based ceramics were obtained by a solid state reaction. A ceramic support, sintered at 1250°C, within an average pore size of about 8 μm, a porosity of about 47% and a compression strength around 40 MPa, was prepared. The microfiltration active top layer was added on the support by a slip casting from clay powder suspensions. The novel microfiltration membrane layer has a thickness of 40 μm and an APS value of about 0.2 μm. This average pore size value was improved and considerably lower than those reported in the literature (0.5 μm). The performance of the novel microfiltration ceramic membrane was determined for evaluating both the water permeability and rejection. This proved the potentiality of the membrane produced in the microfiltration field. Moreover, the good adhesion, between the support and the active microfiltration layer membranes, was also proved. A correlation between microstructures of used powders and physicochemical properties was discussed. Finally, the origin of the unique two powder order membrane depositions was also proposed.

“…A lot of countries in the world have abundantly available raw materials, such as calcite (CaCO 3 ), dolomite (CaCO 3 .MgCO 3 ), bones (natural derived hydroxyapatite, HA, Ca 10 (PO 4 ) 6 (OH) 2 ), kaolin, feldspar and quartz. Many works have already been published for valorizing these native raw materials, for the production of advanced ceramics [1][2][3], ceramic membranes [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and bioceramics [20][21][22][23][24][25][26][27][28][29]. Most of these publications are closely related to this work and clearly highlight their possible multifunctional applications.…”

Porous ceramics of good quality cost a lot in the world market, which has limited their use in developing countries. This is why this work was mainly devoted to prepare low-cost and good quality ceramics, using kaolin (DD2 type) and calcite (CaCO3) available in abundance in Algeria. Based on previous results, 28 wt% CaCO3 ceramic was selected. The presence of CaCO3 favors to achieve porous samples characterized by a high percentage of porosity due to the CO2 release and CaO formation during its calcination at about 700 °C. The choice of these raw materials is based on their natural abundance (low price). It has been found that the samples had interesting characteristics: average pore size between 2.87 and 6.50 μm and porosity between 53 and 57%. It has also been found that the manufactured membrane supports are mainly constituted of gehlenite and anorthite phases. Moreover, the pore size distribution was mono-modal type. The surface and cross-section morphologies observed through a scanning electron microscope were also homogeneous and do not present any possible macro-defects (cracks, etc.).
