Sol–gel derived aluminosilicate coatings on alumina as substrate for osteoblasts

Doping and calcination effect on nanostructured aluminosilicates processed by sol-gel route

“…The biocompatibility of these materials depends on the activity of the cells adhered to their surface and is influenced not only by the composition of the materials but also by their structure. Moreover, the studies have emphasized that nanosized crystalline phases, like nanosized mullite, can increase the cells function in comparison to conventional phases, but it is considered that a spinel phase diminishes the activity of the cells adhered onto these samples surface [7].…”

“…Sol-gel derived aluminosilicates with nanosised mullite particles are interesting candidates for osteoconductive coatings on alumina implants [7]. Biocompatible ferrimagnetic glass ceramics are suitable for hysteresis heating of surrounding tissues [8].…”

Microstructure and oxidation behavior of sol–gel mullite coating on SiC-coated carbon/carbon composites

“…This method offers better control over particle size and morphology of the starting precursor resulting in enhanced sintering ability at low temperatures. This in turn imparts superior mechanical properties to the mullite prepared in this way [17][18][19]. However, coatings prepared by conventional sol-gel processes suffer limitations due to the presence of cracks, porosity and high internal stresses leading to adhesion failures.…”

Novel porous Al2O3-SiO2-TiO2bone grafting materials: Formation and characterization

“…9 Leivo et al 10 studied the osteoblast response to sol-gel derived high-purity aluminosilicate ceramic coatings, with and without nanosized transitional mullite crystals and with various defined nanoscale structures. Cell culture testing by using rat osteoblasts showed good biocompatibility of aluminosilicates with sustained normal osteoblast functions.…”
