Silicates are organosilicon compounds, a majority of which are oxides, that are extensively used in materials science and engineering. Doped silicates confer specific properties to materials. Sigma-Aldrich offers silicates that can be applied to xerogel and silica sol-gel synthesis, formation of hexagonal mesoporous silica layers, to intercalate H+-magadiite, and to the study of mixed-metal bioactive glasses and other bioactive materials utilized in bioengineering.
