This paper addresses the critical need for robust quality assurance in commercial
refractories, emphasizing the role of Ultrasonic Pulse Velocity (UPV) testing in assessing …

The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel
has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the …

The purpose of this study was to investigate behavior and degradation level of refractory
concrete sintered at different temperatures during the thermal stability testing. Alumina …

Thermal shock stability plays a great role in the selection of optimal refractory material.
Different methods of characterization were developed for this purpose, including the …

Thermal shock is a principal cause of catastrophic wear of the refractory lining of high
temperature installations in metal making processes. To investigate thermal shock …

Viscoelastic bridges can be formed in refractory ceramics while cooling from high
temperatures. Such bridges can shield crack tips, thus reducing the effective crack tip stress …

In the present work Mg-exchanged zeolite and silicon carbide were used as starting
materials for obtaining cordierite/SiC composite ceramics with weight ratio 30: 70. Samples …

The purpose of this study was to investigate the mechanical properties and level of
cavitation damage to alumina‐based low‐cement castable. The effects of temperature …

Ultrasonic pulse velocity testing and image analysis were used to predict the thermal
stability of cordierite–mullite refractories. Two compositions used as substrates in fast firing …

In the present work, Mg-exchanged zeolit and silicon carbide were used as starting
materials for obtaining cordierite/SiC composite ceramics with weight ratio 50: 50. Samples …
