Preparation of calcium fluoroaluminosilicate glasses containing sodium and phosphorus by the nonhydrolytic sol–gel method

Biomaterials and Sol–Gel Process: A Methodology for the Preparation of Functional Materials

“…This process enables reaction control and the use of stoichiometric amounts of Al and Si reagents at low temperatures, near 110 o C, thereby reducing production costs. The preparation of aluminosilicate-based matrices by the nonhydrolytic sol-gel method, using varying concentrations of the glass components, especially the element phosphorus, has been accomplished by our group [84]. Figure 18 depicts the X-ray diffractograms for the samples A2, A3.3, and A4, all dried at 50ºC.…”

“…In conclusion, the material IC2 can be used as a basis for glass ionomer cement and the fact that it is synthesized at lower temperature and leads to greater homogeneity compared with the Ca-FAlSi produced by industrial methods makes it advantageous over the commercially available materials. The glass ionomer prepared in reference [84] was tested with respect to its biocompatible properties and compared to the materials obtained by the industrial methodology. Experimental and conventional GIC were analyzed in terms of morphology and of the morphometric reaction induced by the cement in the subcutaneous tissue of rats.…”

Preparation of a GdCaAl3O7 matrix by the non-hydrolytic sol–gel route

“…This methodology is an alternative to the production of multicomponent oxide materials displaying chemical, physical and thermal properties that cannot be obtained by the hydrolytic sol-gel route [13,[29][30][31][32][33][34][35][36].…”

Characterization of the calcium-fluoroaluminosilicate glass prepared by a non-hydrolytic sol-gel route for future dental application as glass ionomer cement

“…This alternative method is based on the condensation between an alkoxide and a metal halide. The alkoxide can be added to the reaction or obtained in situ by reaction of a metal chloride with oxygen donors; i.e., ethers or alcohols, in the absence of water (Scheme 1) [14][15][16] .…”
