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.

Purified quartz powder modified for cladding optic fiber cable

A continuous process and related system for producing high purity silica are disclosed. The process and system utilize a unique high temperature rotary reactor which excludes oxygen. The use of one or more anoxic gases is described, that upon administration into the system promote the exclusion of oxygen.

Continuous reactor system for anoxic purification

A filler material that includes a metal fluoride compound which is coated with silica. The filler material can be used in various types of covering agents.

Fluorspar-based filler and method for making the same

Methods of converting olivine to lizardite without formation of chrysotile or brucite are disclosed. The methods comprise heating a mixture of olivine, silica, water, and a caustic agent. The addition of silica allows for complete conversion of the olivine to lizardite through a more thermodynamically favorable reaction. The olivine and silica are preferably of small particle size to increase reactivity.
