Abstract: A method of making a scintillator material includes forming a dried ceramic composition into a ceramic body with a garnet crystal formula (Gd3-x-zYx)Cez(Ga5-yAly)O12, where x is about 0 to about 2, y is about 0 to about 5, and z is about 0.001 to about 1.0. The ceramic body is sintered to form a sintered ceramic body. The sintered ceramic body is surrounded by a powder mixture that includes a garnet powder. The density of the sintered ceramic body is increased by applying an increased temperature and isostatic pressure to form the scintillator material.

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: 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.
