The influence of microstructure on the maximum load and fracture energy of refractory castables
(ELSEVIER SCI LTD, 2010)
Refractory castables are composed of fractions of fine to fairly coarse particles. The fine fraction is constituted primarily of raw materials and calcium aluminate cement, which becomes hydrated, forming chemical bonds ...
Ceramic coating for refractories protection against carbon oxidation, Part 1: Protection mechanisms
(1999-03-01)
For retarding carbon oxidation in refractories during the preheating of metallurgical furnaces, a ceramic coating, made mainly of sodium phosphosilicate and clay was developed. The coating presents high adherence to the ...

Parallel oxygenators in the same circuit for refractory hypoxemia on veno-venous extracorporeal membrane oxygenation. A 3-patient series
(2023)
Extracorporeal membrane oxygenator (ECMO) is a well-established therapy for respiratory failure. Refractory hypoxemia, despite the use of ECMO, remains a challenging problem. The ECMO circuit may not provide enough oxygenation ...
Laboratory scale study of uncommon degradation SiO2 refractories used on induction furnaces
(2013)
The refractory degradation on induction furnace walls at different points was studied. A SiO2 (98.8%) base refractory was analyzed with two different slag chemical composition through crucible and dipping laboratory ...
Thermomechanical behaviour of Al2O3-MgO-C refractories under non-oxidizing atmosphere
(Elsevier, 2014-11-11)
Al2O3–MgO–C (AMC) refractory bricks are used as linings for the sidewalls (metal line) and bottoms of steel-making ladles. As a structural component of this type of vessel, these bricks undergo mechanical and thermal loading ...
High temperature mechanical behavior of Al2O3-MgO-C refractories for steelmaking use
(Elsevier, 2011-12)
The advantages of Al2O3-MgO-C (AMC) refractories are achieved mainly by the incorporation of graphite and the formation of spinel by solid reaction between alumina and magnesia. Regarding other members of oxide-C refractories ...
Decision making during the psychological refractory period
(Cell Press, 2012-10)
In spite of its massively parallel architecture [1], the human brain is fundamentally limited if required to perform two tasks at the same time [2, 3]. This limitation can be studied with the psychological refractory period ...
