Alkali Metal Silica Gels from SiGNa

SiGNa Chemistry has recently developed a technology for encapsulating alkali metals into nano-structured porous oxides to create stable, free flowing powders with varying reactivities (based on the intended application).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
