Improving thermo-mechanical properties of tabular alumina castables via using nano structured colloidal silica [PDF]
, 2011 Great attempts were made to reduce the amount of calcium aluminate cement (CAC) content in refractory castables to improve their hot strength. Using more than 2-3 wt% CAC may cause low melting phases formation in the refractory matrix leading to weak ...

Refractory concrete: A material that offers new ceramic opportunities. [PDF]
, 2011 Refractory concretes (RC) are industrial materials used most commonly in high temperature applications, primarily in the steel and glass industries. In most cases they are a mix of refractory aggregate’s chosen for specific hot engineering applications ...

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.
