Silica refractories are promising materials for high-temperature thermal energy storage (HT-TES), because they exhibit excellent thermal cycling properties, unless cooled below a critical temperature (usually assumed to be 600 °C). When cooling down

Templated grain growth is a promising method for the fabrication of translucent alumina ceramics and a possible way to circumvent light scattering due to birefringence. In the present paper the effect of temperature, heating rate and dwell time on gr

Generalized mean values of size distributions are defined via the general power mean, using Kronecker's delta to allow for the geometric mean. Special cases of these generalized mean values are the superarithmetic, arithmetic, geometric, harmonic and

The effects of LiF and NaF sintering additives on the grain growth of spinel ceramics prepared via spark plasma sintering (SPS) are investigated and compared for dwell times in the range 0–120 min. Absence of sintering additives resulted in abno

A generalized formulation of transformation matrices is given for the reconstruction of sphere diameter distributions from their section circle diameter distributions. This generalized formulation is based on a weight shift parameter that can be adju

A new generalized cross-property relation is proposed for predicting the relative elastic moduli (Young's modulus, shear modulus, bulk modulus) from the relative conductivities (thermal or electrical) of isotropic porous materials with spheroidal por

Recent work on the elastic constants of plagioclase feldspars is reviewed. Based on the 21 elastic constants (stiffnesses) reported in the literature for triclinic plagioclase monocrystals of different composition, the effective elastic constants of

Minimum solid area (MSA) models are popular models for the calculation of the effective properties of porous materials and are frequently used to justify the use of a simple exponential relation for fitting purposes. In this contribution it is shown

Porous ceramics have a wide range of applications at all length scales, ranging from fi ltration membranes and catalyst supports to biomaterials (scaffolds for bone ingrowths) and thermally or acoustically insulating bulk materials or coating layers
