Spark Plasma Sintering of Magnesium Fluoride Nanopowders

摘要

The densification behavior of nanostructured MgF2 ceramics in the spark plasma sintering process is studied. Nitrate synthesis is employed to produce fine magnesium fluoride powder. The high-purity and fine MgF2 powder has 300-500 nm grains and shows high density (similar to 99.8%) and transparency (similar to 90%) in the infrared range for samples 2.5 mm thick.
