Scope and purpose
Calcined alumina is used both in the production of molded and unformed refractories. Depending on the size of particles and crystals, they perform different functions.

- improve the refractoriness of the final product and service qualities as a whole through the use of cleaner raw materials and an increased content of alumina;
- increase mechanical strength and wear resistance due to optimal particle packing and the introduction of alumina into the finely ground part;
- when interacting with a binder, a matrix phase is formed having high refractoriness and heat resistance.
