Influence of technological parameters on the hot-pressed process of CaF2 optical ceramics

The paper uses the experimental planning method to study the influence of technological parameters on the hot pressing process of CaF2 optical ceramics. The experimental planning model is applied to build the correlation equations between technological parameters, such as temperature, time, and pressure, on the quality index of the transmittance of optical ceramics. From there, the authors determine the optimal set of hot pressing technological parameters for the hot pressing process of CaF2 optical ceramics. The research findings serve as an important basis for further studies on the hot-pressing process of various optical ceramics used in military optical devices.
