quartz grinding methods

Quantitative analysis of quartz in perlite by x-ray ...

grinding in liquid nitrogen were both investigated, but powders produced from each of these methods were too coarse for XRD analysis. While the Microjet 5 grinder can produce a fine- grained powder in a short time, the agate grinding set may con- taminate the perlite with quartz, so the Microjet 5 was not used.

3.1 Full Lap Polishing Processes (Conventional Methods) Principle: There are three popular theories of glass polishing. Hooke, Newton and Rayleigh proposed the 'wear theory', which says that the polishing takes place by the mechanical wear of the abrasives and the surface of glass. In short it is an extension of grinding.
