Despite the continuous evolution on the performance of refractory ceramic products, monolithic materials still require special attention during their processing steps as various phase transformations may take place during the curing, drying and firin

Drying is the most critical process of the first heating cycle of monolithic dense refractories, as the reduced permeability of the resulting microstructure may lead to explosive spalling and mechanical damage associated with dewatering. The first pa

Refractories are key components for the productivity of a calcination unit. Unexpected halts caused by refractory failures directly affect the production plan and lead to considerable financial losses (lost income, additional material purchasing and

Purchasing and installing refractory materials are some of the major baking furnaces’ costs. Usually, the products are selected considering the corrosion during operation. Nevertheless, other variables may affect their performance and must be evalu

This work addresses the main aspects related to the use of alternative binders [hydratable (HA) or colloidal alumina (ColAlu)] in castables containing different spinel sources (pre-formed or in situ generated), in order to point out: (i) the features

Different approaches to master magnesia hydration in refractory castables have been recently proposed. Among them, the use of hydrating agents can change the Mg(OH)2 crystals morphology and its distribution in the resultant microstructure, minimizing

Devido à hidratação e seu efeito expansivo, o uso de magnésias reativas em concretos refratários é usualmente evitado. Entretanto, magnésias cáusticas possuem maior área superficial e menor tamanho médio de cristais quando comparadas ao sí

Although the corrosion performance of spinel-containing castables has been extensively investigated in recent years, no previous studies accessed the different conditions present in the ladle bottom. In this region, strong variations in the atmospher

Calcium aluminate cement (CAC) contents higher than 3 wt% in refractory castables can have some drawbacks in the various processing steps (mainly drying) and also in their refractoriness when in contact with SiO 2 . The use of colloidal silica as an
