Description

An amphoteric oxide, commonly referred to as alumina (α-alumina), aloxide, or corundum in its crystalline form

MP EcoChrom™ Alumina N is an oxide of aluminum, occurring in nature as various minerals such as bauxite, corundum, etc.

It is used as:

  • An adsorbent
  • A desiccating agent
  • A catalyst
  • In the manufacture of dental cements and refractories

Application Notes:

MP EcoChrom™ Alumina N catalyses a variety of reactions that are useful industrially.

It is widely used:

  • To remove water from gas streams
  • For its hardness and strength
  • As an abrasive, including as a much less expensive substitute for industrial diamond
    • Many types of sandpaper use aluminium oxide crystals
  • In chemistry laboratories, alumina is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations, as well as for:
    • Alcohols
    • Hydrocarbons
    • Steroids
    • Alkaloids
    • Natural pigments
    • Neutral alumina (less active than the basic form) is useful for separation of:
      • Aldehydes
      • Ketones
      • Quinones
      • Esters
      • Lactones
      • Glucosides
    • Acidic alumina, is the weakest and least often used type and is useful for separation of acid pigments and strong acids. It can cause:
      • Polymerization
      • Condensation
      • Dehydration reactions
    • Neither acetone nor ethyl acetate should be used as eluants, the latter being subject to saponification.
  • A dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties
