Impact of Distinct Ca${}^{2+}$ Sources on the Physical Properties of Alumina-based Macroporous Refractories for Thermal Insulation at High Temperature

O. H. Borges, T. Santos, R. R. B. Oliveira +2

Calcium aluminate cement (CAC), calcium carbonate (CaCO${}_3$), calcium hydroxide [Ca(OH)${}_2$] and calcium oxide (CaO) were investigated in alumina-based macroporous compositions for…
