ABSTRACT:
A component that is reflective for broadcast-frequency energy includes a nonmetallic substrate having a substrate surface, and a layered coating overlying and contacting the substrate. The layered coating has an electrically conductive layer overlying and contacting the substrate surface, and a layer of a white paint overlying and contacting the electrically conductive layer. The white paint is formed of a plurality of particles including a plurality of pigment particles. Each pigment particle has a composition of A[xAl(1−x)Ga]2O4(δD), A is selected from the group consisting of zinc, cadmium, and magnesium, D is a dopant selected from the group consisting of a cationic dopant having an ionic valence greater than +2 and an anionic dopant, the value of x is from 0 to 1, and the value of δ is from 0 to about 0.2. The paint further includes an inorganic or an organic binder mixed with the particles to form a mixture.
