摘要： A highly purified quartz powder having a low level of naturally occurring lithium modified for cladding a fiber optic cable, said modified quartz powder having an increased total amount of lithium in solid solution in said powder, said increased total amount being in the range of more than 0.50 ppm and less than 1.00 ppm and a method of modifying an highly purified quartz powder to make the same.
