The invention relates to the technical field of stealth material preparation, in particular to transparent
microwave radar-
laser dual-band stealth glass, a preparation method and application, the transparent
microwave radar-
laser dual-band stealth glass comprises the following
raw material components: K2O, CaO, B2O3, SiO2, ZnO, Al2O3, 0.1 wt%-0.5 wt% of Fe2O3 or 0.1 wt%-0.5 wt% of Co3O4 and 3wt% of Si; wherein the
molar ratio of (K2O + CaO): (B2O3 + SiO2): ZnO: Al2O3 is (5-15): (35-45): 50: (0-20), the
microcrystalline glass prepared from the raw materials comprises a high-loss and high-
conductivity wave-absorbing Zn1-xFexO or Zn1-xCoxO
microcrystalline phase and a low-loss and wave-transparent K2O-CaO-B2O3-SiO2-ZnO-Al2O3-Fe2O3-CoO glass phase, has
high transmittance at 750nm, has good
impedance matching characteristic between the material and an empty interface, and can be used for preparing the wave-absorbing
microcrystalline glass of the wave-absorbing Zn1-xFexO or Zn1-xCoxO / K2O-CaO-B2O3-SiO2-ZnO-Al2O3-Fe2O3-CoO glass. In addition, Fe < 2 + > and Co < 2 + > obtained after reduction of Si
powder at a high temperature in the
glass matrix can absorb
laser radar light
waves, so that the microcrystalline glass has visible light transparency and
microwave radar-laser dual-band stealth functions, and the problems that an existing wave-absorbing material is poor in light
transmittance and cannot meet stealth protection of occasions with light
transmittance requirements are solved.
