Since electrical conductivity in fused quartz is ionic in nature, and alkali ions exist only as trace constituents, fused quartz is the preferred glass for electrical insulation and low loss dielectric properties. Both electrical insulation and microwave transmission properties are retained at very high temperatures and over a wide range of frequencies.
