چکیده:

In this work, the effect of most important parameters of hot pressing, including temperature, time and pressure on densification, microstructure and infrared transparency of MgF2 ceramics have been discussed. The results show that by increasing the temperature or the pressure, transparency in infrared wavelengths increases due to the rise in density. By increasing the hot pressing time, a continuous increase in density and infrared transparency occurs and the amount of porosity decreases. Cold pressing and preheating before the hot pressing have minor effects on the density and infrared transparency of MgF2.
