Method of preparing nanoscale magnesium fluoride transparent ceramic through hot pressing method
The invention relates to a method of preparing nanoscale magnesium fluoride transparent ceramic through a hot pressing method, which belongs to the technical field of transparent ceramic materials. The method has the characteristics of simple technological process, high preparation speed, high efficiency and the like. The obtained MgF2 transparent ceramic is uniform and fine in crystal grain (theaverage is smaller than or equal to 100 nm), the bending strength is larger than 140 MPa, the Vickers hardness is larger than 700 kg/mm<2>, the visible light wave band (350-770 nm) has certain transmittance (the average is larger than 40%), and the obtained MgF2 transparent ceramic is particularly suitable for being used as a medium-wave-transmitting infrared window/cover material.
本发明涉及一种热压法制备纳米级氟化镁透明陶瓷的方法，属于透明陶瓷材料技术领域。该方法获得的该方法具有工艺过程简单、制备速度快、效率高等特点，所得到的MgF透明陶瓷晶粒均匀细小(平均≤100nm)，抗弯强度>140MPa，维氏硬度>700kg/mm，可见光波段(350‑770nm)有一定透过率(平均>40％)且特别适合用于透中波红外窗口/罩体材料。
