FUSiO2N™, an outstanding fused silica family of materials, was developed to optimize life of your refractory and molten metal handling components without compromising thermal insulation properties. FUSiO2N materials are used in trough applications with medium to high flow rates. FUSiO2N SL and SP are used in ladles, pour basins, pins and spouts, nozzles, filter bowls, dams and many other applications. This material is extremely insulating, does not need pre-heating, and avoids aluminum build up saving $$$ in both energy and scrap metal. In addition, users will agree that FUSiO2N components last longer!
