A method and apparatus for making highly pure silica powder by milling the substantially pure SiO 2 charge in a ball mill which is made with an interior lining of contiguous silicon nitride plates or tiles and which employs silicon nitride media. The silicon nitride plates and media prevent contamination of the silica charge while minimizing their deterioration.

The amount of alumina contamination present in ball-milled silica powders has been shown to increase with increased mill time for materials manufactured during the same time period. This alumina contamination level has also been observed to vary depending on the date, and possibly the state of repair, of the ball mill itself.
