“…realized a parametric study of magnesium silicate precipitation in the presence of sodium hydroxide solution. Precipitation was performed by “a drop‐by‐drop mixing of solutions of sodium metasilicate and magnesium salts” (chloride, sulfate, and nitrate) at 80 °C (Figure a) . The presence of a sodium hydroxide solution during the precipitation significantly affected the quality of the obtained magnesium silicate (modification of chemical composition, lower particle size, and higher homogeneity of particle size).…”

This contribution gives a comprehensive review about the progress in preparation methods, properties and applications of the different synthetic talc types: i) crystalline nanotalc synthesized by hydrothermal treatment; ii) amorphous and/or short-range order nanotalc obtained by precipitation, and iii) organic-inorganic hybrid talc-like structures obtained through a sol-gel process or a chemical grafting. Several advantages of nanotalc such as high chemical purity, high surface area, tunable submicronic size, high thermal stability, and hydrophilic character (leading to be the first fluid mineral) are emphasized. Synthetic nanotalc applications are also considered including its use as nanofiller in composite materials, as absorbers of organic compounds, as anticorrosion coatings and as agents for cosmetic applications. Regarding their high industrial application potential, intensive research has been carried out to better understand their behavior and develop processes to produce them. To facilitate further research and development, scientific and technical challenges are discussed in this Review article.

“…Clinoenstatite was reported as one of the four polymorphic forms of MgSiO 3 (enstatite, protoenstatite, clinoenstatite, and high‐temperature clinoenstatite) 11–15 . The sol–gel synthesis, 16–18 modified pechini, 19 precipitation method, 20,21 and solid‐state reaction methods 11,22–25 have been used to synthesize MgSiO 3 powders. Merle and colleagues 22–25 fabricated enstatite bioceramics with 5–15 wt% Ca–P glass or Ca–P–Al glass component, and the studies showed that the materials possessed good cell biocompatibility and mechanical properties.…”

Clinoenstatite (MgSiO 3 ) powders were synthesized by precipitation process using magnesium nitrate (Mg(NO 3 ) 2 . 6H 2 O) and sodium silicate (Na 2 SiO 3 . 9H 2 O), and clinoenstatite ceramics were prepared by sintering its powder compacts at 14001C for 3 and 5 h. The shrinkage (4.53%), bending strength (31.78 MPa), relative density (82.84%), and Young's modulus (8.51 GPa) were investigated. The percentages of weight loss of the clinoenstatite ceramics were listed as 1.2970.55%, 1.3670.30%, 7.3171.54%, and 10.7770.93% after 1-, 3-, 7-, and 14-day soaking in the Tris-HCl solution. The biocompatibility studies showed that clinoenstatite ceramics could not induce the formation of HAp in simulated body fluid, but the ionic products of the clinoenstatite powder extracts promoted the proliferation of the mouse fibroblasts (L929 cell). The murine embryonic mesenchymal stem cells adhered well and proliferated more on the clinoenstatite ceramics than on the traditional hydroxyapatite ceramics. These results showed that clinoenstatite bioceramics possessed good cell biocompatibility and might be used for preparation of bone implants or biocoatings.

“…This aim could be achieved by using lower porosity matrices, restricting humidity variations from the outside environment. In this case MgO-based cement seems to have a higher apparent density (KRYSZTAFKIEWICZ et al, 2004).…”
