Mullite macro-needles for reinforcement of refractory castables

Cerâmica, 2022
Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase.

Effect of Specimen Size on the Resistance to Thermal Shock of Refractory Castables Containing Eutectic Aggregates [PDF]

Materials Research, 2015
Thermal shock is one of the most severe conditions to which a refractory lining can be subjected to during its industrial application. Thus, there are several methods available for testing thermal shock damage resistance of refractories.

Variação do tamanho de grão da magnésia: um exemplo da complexidade de cerâmicas refratária Changing the magnesia grain size: an example of refractory ceramics complexity

Cerâmica, 2010
Concretos refratários alumina-magnésia apresentam um comportamento expansivo devido à espinelização in-situ, sendo que a fonte de magnésia e o seu tamanho de grão influenciam tal reação.

The Effect of Deflocculants on the Structure and Physical-Mechanical Properties of Fireclay Refractory Castables

Medžiagotyra, 2012
For production of fireclay refractory castables, various deflocculants are used. In recent years new polycarboxylate ethers-based deflocculants appeared and so far their properties comparing to those of common deflocculants are little investigated.

Effect of Prewetting Cenospheres on Hydration Kinetics, Microstructure, and Mechanical Properties of Refractory Castables

Crystals
This study investigated the effect of non-prewetted and prewetted cenospheres (CSs) on the hydration course and physical and mechanical properties of refractory castable mixtures incorporated with nano silica (NS). The fixed amount of 0.1% of NS improves
