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.

Bonding scintillator material to produce large panels or other shapes

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.

Methods and apparatus for components according to various aspects of the present invention operate in conjunction with reaction bonded silicon nitride (RBSN). In one embodiment, a missile radome comprises a wall defining the radome body, including a base and a tip. The wall may comprise a core and one or more skins adjacent the core, such as in a sandwich configuration. The core and the skins may have different densities. The radome wall may be configured to transmit wideband RF signals. The RBSN may be extruded to form the radome.
