Glass

 

Glass is an amorphous material that benefits from the presence of alumina to enhance strength, and thermal and chemical resistance. It also improves the process of glassmaking with respect to melt viscosity, vitrification and working temperature.  There are many familiar applications using glass including:
  • Display and coverglass for LCD and OLED screens for TV, monitors, laptops, tablets, smartphones, etc...
  • Photovoltaic glass for solar panels  
  • Flat or float glass for the construction and automotive industries 
  • Tableware and cookware 
  • Bottles and jars 
  • Bottles for perfumes 
  • Pharmaceutical and laboratoryware 
  • Glass ceramics for cooking surfaces
  • Glass fibres

Calcined alumina

Aluminas with intermediate to relatively high specific surface areas (BET 3- 75m²/g) with alpha alumina contents varying between 20% and 95%.These are produced by controlled rotary calcination of aluminium trihydroxide.

AR304 AR4 AR75 AR8
Coarse alumina hydrate

Aluminium trihydroxide (ATH) is produced by the Bayer Process in Gardanne. These ATH grades are used for the production of a variety of aluminium salts and in glass production.

SH500 SH950
Hard calcined alumina

These aluminas have low specific surface area (BET < 1m²/g) and are almost entirely alpha alumina. Standard soda content is 3000-4000 ppm and intermediate soda content is 2000-3000 ppm.  Hard calcined aluminas are produced in rotary kilns.   

AC44 AC45
Low soda alumina

This alumina has very low soda content: between 300 and 500ppm. Carefully controlling calcination using the proprietary Reynolds process also allows a wide range of primary crystal size to be offered.
