A New and Economic Approach to Synthesize and Fabricate Bioactive Diopside Ceramics Using a Modified Domestic Microwave Oven. Part 1: Study of Sintering and Bioactivity

Abstract

Diopside (CaMgSi2O6) ceramics was synthesized and fabricated by a simple solid‐state reaction rather than other used processes. This new and economic approach for diopside fabrication consists mainly of replacing the usually used starting materials by other more economic (activated CaO·MgO powders), using conventional sintering and microwave sintering. The P2O5 addition (0.5–5.0 wt%) promotes sintering, crystallization, and bioactivity. Additionally, a considerably low weight loss ratio (0.21%) was also obtained for these samples, after 2 days of soaking in lactic acid. Carbonated hydroxyapatite (CHA) formation in simulated body fluid was confirmed for all sintered samples. Both sintering and CHA formation mechanisms were proposed.

Mechanical properties of anorthite based ceramics prepared from kaolin DD2 and calcite

“…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.…”

Development and characterization of tubular composite ceramic membranes using natural alumino-silicates for microfiltration applications

“…Algeria is one of the countries in the world that have abundantly available raw materials, such as calcium carbonates (CaCO 3 )(CC), 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][4][5][6][7], ceramic membranes [8][9][10][11][12][13][14][15][16][17][18][19] and bioceramics [20][21][22][23][24][25][26][27]. In particular, in the membrane field the possibility of replacing the more expensive starting materials by cheaper raw materials to be used as a support (which constitutes about 99% of the filter mass) is significantly important from economic and energetic points of view.…”

“…Algeria is one of the countries in the world that have abundantly available raw materials, such as calcium carbonates (CaCO 3 )(CC), dolomite (CaCO 3 MgCO 3 ), bones (natural derived hydroxyapatite (HA): Ca 10 (PO 4 ) 6 (OH) 2 ), kaolin, feldspar and quartz.
