quartz fiber is drawn from the fused high purity quartz sand. The
SiO2 purity can reach up to 99.99%. Due to remarkable properties of
high temperature insulation, electricity insulation and wave transmissibility,
it is widely used in industries such as space, aviation，electronics,
metallurgy, petro-chemistry, cable and atomic energy.
