3N5 (99.95%) Magnesium Oxide (MgO) Pieces (1-3mm) Evaporation Materials

Magnesium oxide (MgO) is a traditional raw material for use in a wide range of products such as refractory, paints, paper, plastics, rubber, oil, pharmaceutical, fertilizer and animal feed. More recently, it is being used as an additive in superconductor products, waste treatment agent for neutralizing acids or cleaning water and as a catalyst material. A thin layer of evaporation MgO is used as buffer layer between superconductor and substrate. MgO coating is also used to improve the performance as a cathode material for Li-ion batteries at elevated temperatures and to improve corrosion resistive behavior of Mg alloys and steels.
