Silicon Oxide (SiO2) Powder

Silicon oxide is a highly insoluble thermostable silicon source suitable for glass, optics and ceramic applications. Oxide compounds do not lead to electricity. However, some structured perovskite oxides are an electroconductive research application in the cathode of solid oxide fuel cells and in oxygen generation systems. They are compounds that contain at least one silicon oxide (SiO2) powder of high oxygen purity (99.999%) and a metal cation. Generally, they are insoluble in aqueous (water) and extremely stable solutions, so they are useful in simple ceramic structures such as producing clay pots for advanced electronic components and light structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. The metal oxide compounds are basic anhydrides and, therefore, can react with acids and strong reducing agents in the oxidation-reduction reactions. Silicon oxide is also available in pellets, parts, powders, pulverizers, tablets, and nanopowders (from the nano-scale production facilities of Nano Research Elements). Silicon oxide is generally available immediately in most volumes. Forms of ultra high purity, high purity, submicron and nanopowders can be considered. Nano Research Elements produces many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technique Degree; Food, agricultural and pharmaceutical grade; Optical Grade, USP and EP / BP (European Pharmacopoeia / British Pharmacopoeia) and follow applicable ASTM test standards. Typical and customized packages are available. Additional technical, research and safety information (MSDS) is available, as well as a reference calculator for converting the relevant units of measure.
