    摘要: 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.
