Development of TiO2-doped MgO refractories with enhanced corrosion resistance for preparing high-purity nickel-based superalloys

Journal of Materials Research and Technology
MgO refractories extensively applied in melting nickel-based superalloys are limited by their poor thermal shock resistance and susceptibility to melt erosion. This study regulated the phase composition of MgO refractories by doping TiO2 to improve their

Magnesia‐carbon refractories from recycled materials

International Journal of Ceramic Engineering & Science, 2022
Recycling of used refractories – in particular closed‐loop recycling – gains in importance because of both ecological and economic benefits, such as the conservation of natural resources, reduced landfilling, and the reduction of greenhouse gases and ...

Dimension limit for thermal shock failure

, 2014
We analytically present the characteristic dimensional limit below which the thermal shock failure of ceramics never occurs. This limit, together with the critical temperature difference, separates the state space of the ceramics under thermal shock into

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

On thermal shock behavior of functionally graded materials

, 2007
Cracking is a common phenomenon for many media subjected to a rapid temperature change. Cracks in a medium may be in the form of either a single dominant crack or an array of multiple cracks. In this article a review is given of our work on this subject.
