Abstract

For the first time the possibility of synthesizing of an optical ceramics MgF2 using a powerful electron beam as a heater is shown. In the process of synthesis, the charges consisting of magnesium fluoride powder with different ratio between the dopants WO3 and LiOH were exposed to an electron beam with 1.4 MeV electron energy and power of 18 kW on an area of 1 cm2. Investigations of the elemental composition and structure of the synthesized ceramics showed the presence of crystalline phases MgF2, W, WO3, and Mg in the samples. The size of the crystalline grains and efficiency of their formation depend on the composition of the charge. It was found that the synthesized ceramics samples luminesce in the 470 nm region at 300 K. Excitation spectrum of this emission in ceramics consists of two bands with maxima at 250 nm and about 200 nm. The spectral properties of MgF2 ceramics in general are similar to those in ZnWO4 single crystals and LiF crystals doped with tungsten oxide.
