Technical Examples

A salt mixture used for chemical strengthening of data recording disks is subjected to sub-micron filtration prior to use to remove certain impurities. Preferably, glass disks are chemically strengthened by ion exchange in a bath of molten sodium nitrate and potassium nitrate. A salt fresh mixture is prepared by starting with high-grade bulk salt in the intended proportions, melting the salt, and filtering the salt in a stainless steel filter, which is preferably approximately 2 micron or smaller. Filtration removes trace amounts of certain contaminants. The salt mixture thus prepared is then used for chemical strengthening of disks in the conventional manner.
