Paper Title:
Study on the Addition of SiO2 into Lithium-Iron-Phosphate Glass
  Abstract

Different amounts of SiO2 were used to substitute P2O5 to prepare lithium-iron-phosphate glass melts. It was found that glass can only formed after annealing the melt cast sample if the sample contains SiO2 not more than 5 mol%. The addition of 5 mol% SiO2 into the lithium-iron-phosphate glass strengthens the phosphate glass network. The density, chemical durability, both the transition and crystallization temperatures increase with the addition of SiO2. In addition, the addition of SiO2 results in the decrease in the activation energy of lithium-iron-phosphate glass, making the glass easier to crystallize. However, both the lithium-iron-phosphate glass and the glass with SiO2 show surface crystallization with LiFeP2O7 as the crystalline phase.
