Abstract:
A method of bonding includes applying a glass composition to at least a first material surface. The glass composition includes a glass powder and a solvent. The first material surface is disposed onto a second material surface. An elevated temperature is applied to the first material surface and the second material surface to form a bond between the first material surface and the second material surface. The first material surface and the second material surface are compressed under an isostatic pressure.
Abstract:
A fused silica body comprising a layer of vitreous silica adjacent at least a portion of an inner surface is described in embodiments herein. In other embodiments, a method of making a fused silica body with a layer of vitreous silica adjacent at least a portion of an inner surface is described herein, comprising heating at least a portion of the inner surface to the point of vitrification. In certain embodiments, the method involves passing a linear local heat source over the inner surface in a particular manner, such as a helical fashion transverse to the linear shape, and may involve creating on the inner surface of the body overlapping swaths of temporarily melted silica material.

Abstract:
An article transparent to radiofrequency (RF) signals includes a substrate and a coating arrangement on the substrate. The coating arrangement includes a primer applied to and in physical contact with the substrate, a topcoat applied to and in physical contact with the primer layer, the topcoat including an organic polymer material, and nanoparticles dispersed throughout one of the primer and the topcoat. A content of the nanoparticles ranges from 0.1 wt % to 10 wt %.
