Reference information on impurity control in ultra-high-purity materials

  • Tungsten metal – 99.9%
  • Aluminum oxide – 99.99%
  • Silicon carbide – 99.999%
  • Quartz sand – 99.999999%

For specific high-purity electronic material systems, the introduction of each individual metallic impurity can be controlled to ≤1 ppb (with a total content of ≤5 ppb), while the introduction of certain non-specified metallic impurities is limited to ≤10 ppt.
