The technology and properties of corundum heat storage materials

  • Published:
Refractories Aims and scope

Conclusions

A technology was developed for the production of corundum lenses from unfired commercial grade alumina containing over 99% Al2O3. The porosity of the lens is 20% or less, the cold-crushing load varies 650–2900 kgf, and the abrasion resistance approaches that of cast corundum balls.

A small amount of magnesium oxide added to the batch improves the abrasion resistance of the lens.
