“…One can compare the obtained flexural strength values using the present work with those reported by other studies carried out on anorthite based ceramics and particular materials [35]. For example, the best 3PFS (203 MPa) in this work was obtained for the anorthite sintered at 950 °C for 1 h using the original milling system.…”

“…In this work, the long-term goal is the development of a low cost anorthite from inexpensive raw materials, such as kaolin and calcite (CaCO 3 ) using a modified milling system. Many works have already been published for appreciating these native raw materials including bioceramics [9][10][11][12][13][14][15][16][17], advanced ceramics [18][19][20][21][22][23][24][25][26][27] and ceramic membranes [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Most of these publications are closely related to this work and clearly highlight their possible applications.…”

As far as ceramic membranes publications are concerned [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42], a lot of low cost materials were also fabricated using the abundantly available raw materials as mentioned above.

“…For example, the best 3-point flexural strength (3PFS) was about 41 MPa for samples sintered at 1250 °C for 1 h, when 15 wt% doloma (CaO.MgO) powder was added into kaolin. Also, a 3PFS value of about 87 MPa was obtained in [35], using kaolin +15 wt% calcite (K15C) selected mixture, sintered at 1250 °C for 1 h. In this way, the anorthite (CaO.Al 2 O 3 .2SiO 2 ) based ceramics were prepared from kaolin halloysite type (Al 2 O 3 .2SiO 2 .4H 2 O) and CaCO 3 using a modified milling system. In fact, the porosity and the APS of samples sintered at different temperatures ranging between 800 and 1100 °C were investigated.…”

Anorthite is widely spread in nature and belongs to the plagioclase group of rock forming minerals. Plagioclases represent a continuous series of solid solutions between anorthite (CaO.Al 2 O 3 .2SiO 2 ) and albite (Na 2 O.Al 2 O 3 .6SiO 2 ) and form an enormous group of triclinic minerals. harabi52@gmail.com, Zaiou_21@yahoo.fr, guechia@yahoo.fr, semouni84@gmail.com, kanour17@yahoo.fr, foughali_lazhar@yahoo.fr, zouaisouheila@yahoo.fr, mezahif@yahoo.fr, guerfatiha@gmail.com Mineralogically, anorthite is reported as a chemically weak mineral, resulting in a basic reaction when dissolved into boiling water, while strong acidic and basic solutions dissolve it. Glass-ceramics and ceramics with crystalline anorthite are mainly used in electrical, thermo-mechanical and water resistance applications [1][2][3][4]. Anorthite is an important technical ceramic material that has good physical properties, such as very low thermal expansion coefficient, low dielectric constant and loss, good thermal shock resistance, and high creep resistance at high AbstractGood quality ceramics costs a lot that has limited their use in developing countries. This work was devoted to prepare low-cost and good quality anorthite based ceramics. The proposed composition was 80 wt% kaolin (DD2 type) and 20 wt% calcium oxide (CaO). The choice of these raw materials was dictated by their natural abundance coupled with a modified milling system, as another interesting advantage. Previous studies have shown that a simple vibratory multidirectional milling system using bimodal distribution of highly resistant ceramic milling elements has been successfully applied for obtaining fine powders. The influence of the relatively lower sintering temperature, ranging from 800 to 1100 °C, on the porosity and the average pore size (APS) have been investigated. The APS and the porosity values of samples sintered at 950 °C were about 1 μm and 4%, respectively. The best Vickers microhardness and 3-point bending strength values for these sintered samples, using this proposed milling system, were 7.1 GPa and 203 MPa, respectively. Finally, the crystalline phase evolution during heat treatment was investigated by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy techniques.

Ceramic Membranes for Citrus Fruit Juice Clarification: A Systematic Review

et al. 2023

View full text Add to dashboard Cite

Membrane separation processes are becoming a significant part of fruit juice processing industries because of their excellent selectivity, absence of thermal and chemical treatments, and energy efficiency. Specifically, the applicability of ceramic membranes in citrus fruit juice clarification is more promising as they are highly stable in a corrosive environment and have a longer lifetime. However, ceramic membranes are costlier than polymeric membranes due to the high cost of raw materials. Therefore, numerous alternative low‐cost precursors for making the ceramic membrane are being utilized. Accordingly, the current review is focused on the different low‐cost raw materials and various fabrication methods to synthesize different ceramic membranes. Further, the ceramic membrane's application in fruit juice clarification is intensely discussed. In any membrane separation process, fouling is an unavoidable constraint. In the current review, various mechanisms involved in fouling are emphasized in detail. In addition, a variety of techniques to reduce fouling are extensively deliberated. Furthermore, ceramic membranes' challenges and future perspectives for further development are also systematically highlighted.

Porous ceramics with high open porosity and good mechanical properties were successfully prepared from fly ash rich in CaO. An addition of 30–50wt.% dolomite decreased the average pore diameter from ∼11.79 μm to ∼2.82μm due to the decrease of viscosity with high dolomite addition, while there is an increase in open porosity from 48.63% to 53.23%. SEM results suggested that pores were firstly surrounded by glassy phase. With the addition of more than 30 wt.% of dolomite, pores were covered by loose structure. XRD results showed the changes in crystal phases of sintered ceramics, from anorthite sodian to alkaline basalt and then to calcium magnesium silicate. CaO and MgO from decomposed dolomite were proposed to be the main reason on modification closed pores to open ones. Except this, CO2 emission and crystalline water emission during sintering were also contributed to the formation of open pores in porous ceramics.
