Optimization of Properties for Alumina-Spinel Refractory Castables by CMA (CaO-MgO-Al2O3) Aggregates
Materials, 2021 Aiming at optimizing properties of alumina-spinel refractory castables, coarse corundum particles were replaced partially with the particles of a novel porous multi-component CMA (CaO-MgO-Al2O3) aggregate in the same size.

Binder effect on ZnAl2O4-containing high-alumina refractory castables
Ceramics International, 2022 In situ spinel (MgAl2O4, ZnAl2O4, etc.) formation in alumina-based castables has been pointed out as a key issue in the refractory area, as it may enhance the mechanical properties and corrosion resistance of such materials.

Improvement in Slag Resistance of No-Cement Refractory Castables by Matrix Design
Ceramics, 2020 The corrosion resistance of spinel containing cement bonded castables has been extensively investigated in the past. However, corrosion of no-cement refractory castables (NCC) has not been widely studied since the use of NCC has been relatively limited ...

Drying behavior of dense refractory castables. Part 2 – Drying agents and design of heating schedules [PDF]
Ceramics International, 2021 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.

Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables [PDF]
Cerâmica, 2021 Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of ...
