Graphite purification is commonly required across a broad range of semiconductor applications.

Metallic impurities are inherent in today’s graphite and carbon products. MWI has spent decades on proprietary purification processes that remove these bad elements down to verifiable limits.

  • High Temperature and Halogen Purification
  • Impurity level to <2 parts per million (PPM)
  • Collaborating with leading independent laboratories for full periodic purity analysis & verification
  • Internal ASH analysis
  • High Temperature furnace toll services available
