Resumen o descripción

The development of innovative chrome-free basic bricks based on

electrofused MgO-CaZrO3 technology using as ceramic bonding

two different types of spinel (hercynite and magnesium-aluminium

spinel) to improve their properties is presented. Microstructural,

physical, mechanical, and thermal properties of electrofused

MgO-CaZrO3 matrix were determined. Static and dynamic resistance

tests by chemical attack of cement raw constituents were carried

out. The results showed that thermo-mechanical properties

of new bricks significantly improved with increasing spinel content.

Microstructural analysis revealed that the spinel phase aided

to develop a strong bond between the magnesia and calcium zirconate

refractory phases. Finally, this refractory matrix exhibits a

good thermal stability and excellent chemical resistance against

cement raw meal.
