Process for producing micro cultured quartz.

摘要

A process for producing micro cultured quartz comprising using microparticle-shaped cristobalite as a raw material in producing cultured quartz according to a hydrothermal growth method. According to the present invention, micro cultured quartz can be obtained without a pulverizing treatment and hence without the contamination with impurities therein. The micro cultured quartz can be utilized for reinforcing fillers, spacers, raw materials of fused quartz and the like.
