What is HPA?

  • Aluminum oxide (Al2O3) is generally known as alumina
  • Alumina is widely used in many large product categories, such as refractories and substrates in electronics
  • Most alumina is produced from bauxite ore, as is aluminum metal
  • Alumina that is at least 99.95% pure is referred to as High Purity Alumina or HPA
  • HPA has valuable properties that make it an important material on the manufacture of LEDs, battery separators and other electronic devices
