“…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.…”

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.

“…Many works have already been published in three main interesting research topics for the valorization of these native raw materials. These topics are bioceramics [3][4][5][6][7][8][9][10][11][12][13][14], advanced ceramics [15][16][17][18][19][20][21][22][23] and ceramic membranes [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40].

In this work, the preparation of anorthite based ceramics using a modified milling system and 80 wt% kaolin (DD2 type) and 20 wt% calcium oxide extracted from CaCO3 is shown. The choice of these raw materials was dictated by their natural abundance. Previous studies have shown that a simple and vibratory multidirectional milling system using a bimodal distribution of highly resistant ceramics can be successfully used for obtaining fine powders. The prepared samples were sintered at different temperatures ranging between 800 and 1100 °C. It has been found that the relative density of samples sintered at 900 °C for 1 h with a heating rate of 5 °C/min was about 96% of the theoretical density of anorthite (2.75 g/cm3). Finally, the prepared samples were also characterized by scanning electron microscopy, X-ray diffraction and Raman spectroscopy.

“…A favourable microstructure can be achieved both through appropriate heat treatments and through the use of additives that can act as nucleating agents [237]. The main methods of obtaining bioactive glasses and glass ceramics are the traditional melting techniques [238], the sol-gel method [239][240][241], the synthesis assisted by ultrasound [242], microwaves [243] or the hydrothermal synthesis [244].…”

Biomaterials are mostly any natural and synthetic materials which are compatible from a biological point of view with the human body. Biomaterials are widely used to sustain, increase, reestablish or substitute the biological function of any injured tissue and organ from the human body. Additionally, biomaterials are uninterruptedly in contact with the human body, i.e., tissue, blood and biological fluids. For this reason, an essential feature of biomaterials is their biocompatibility. Consequently, this review summarizes the classification of different types of biomaterials based on their origin, as natural and synthetic ones. Moreover, the advanced applications in pharmaceutical and medical domains are highlighted based on the specific mechanical and physical properties of biomaterials, concerning their use. The high-priority challenges in the field of biomaterials are also discussed, especially those regarding the transfer and implementation of valuable scientific results in medical practice.
