ATH

Mineral: ATH

 

ATH (aluminium tri hydrate, chemical formula Al(OH)3) is an intermediate product of aluminium production, characterised by: 

  • High purity
  • High whiteness
  • Relatively low density of 2.4g/cm3 compared to other mineral fillers, which are typically at 2.7g/cm3
  • Medium Mohs hardness of 3
  • Decomposition around 200°C, releasing water
