Paper Title:
Preparation Research of CaB6 Powder by Self-Propagating High-Temperature Synthesis
  Abstract

Self-propagating High-temperature Synthesis (SHS) method was adopted to synthesize powder containing CaB6, and the power was leaching by sulfuric acid. Effects of reaction atmosphere, magnesium addition, H2SO4 acidity and leaching temperature on the performances of CaB6 powder was investigated, the microstructure of products were researched by SEM and XRD, the results show that the phases of products by SHS are CaB6、Mg3B2O6 and Ca3B2O6, and high purity CaB6 powders are obtained after the products by SHS was leaching by Sulfuric acid. The SHS conditions are the vacuum atmosphere and 30% excessive magnesium addition and the leaching conditions are 55% acidity of Sulfuric acid and 40°C leaching temperature, the perfect and uniform grain of CaB6 powers are obtained at the above conditions.
