The muonium atom {mu}{sup +}{ital e}{sup {minus}} is a simple system from which to gain information about the {ital e}-{mu} interaction both to test the existing theory of QED and to search for physics beyond the standard model. A systematic study has been carried out of the production and properties of thermal muonium from a fine silica powder. The velocity and angular distributions are examined, as well as the experimental conditions resulting in the optimum production rate. The particular properties of silica powder that give it its muonium-producing capability are investigated. These studies are carried out in the context of a diffusion model, the validity of which is examined.
