Effect of B2O3 Concentration on the Properties of Transparent Magnesium Aluminate Spinel Ceramics

Аннотация

We consider the potential of using boron oxide as a sintering aid for the fabrication of transparent magnesium aluminate spinel (MAS) ceramics and analyze the general tendency in the effect of B₂O₃ concentration on the average density, open porosity, and optical transmission of MAS ceramics. Boron oxide is shown to have an advantageous effect on the sintering behavior of MAS ceramics: raising its concentration leads to a decrease in open porosity and an increase in the average density of the material.
