Abstract
The smoothness of refractory dielectric bodies, particularly silica sol-gel bodies, is substantially improved by a relatively straightforward treatment. In particular, the surface of the body is treated with a plasma fireball, such as induced by a plasma torch. The treatment is able to reduce the roughness, as measured by RA, in overcladding tubes formed by a sol-gel process by at least a factor of 2, typically at least a factor of 5. It is also possible to improve the smoothness of silica tubes that are drawn from a billet. Typically, the process reduces the roughness of silica bodies to an RA of about 1 microinch or less.
