modified purified quartz powder for sheathing fiber optic cable and method of modifying a highly purified quartz powder

摘要

The present invention relates to highly purified quartz powder (100) having a naturally occurring low level of lithium modified to coat a fiber optic cable, said modified quartz powder having an increased total amount of lithium, in the solid solution in said powder, said total amount being increased in the range of more than 0.50 ppm and less than 1.00 ppm, and a method of modifying a highly purified quartz powder (10) to do the same.
