Refractory masonry with dry joints is widely employed as a protective lining in industrial applications requiring high-temperature treatments. The thermal and mechanical behaviour of alumina spinel refractory investigated for wide range loading conditions at ambient high temperature up to 1500 °C within the framework ATHOR project. This paper discusses different numerical analysis approaches si...

Excellent performance of refractories in blast furnace hearth is one the important factors to ensure longevity furnaces. As an emerging refractory for application furnace, alumina-carbon composite brick combines superior properties carbon and alumina. Firstly, thermal conductivity was measured by laser flash method new device verify feasibility measurement. Secondly, influence heating temperatu...

Zr1-xSnxO2 reinforced alumina-mullite refractory was manufactured by slip cast methods using SnO2 as a sintering agent. had considerable influence in the enhanced reaction kinetics of zircon dissociation and subsequent alumina zircon. Presence pro-eutectic transient Al2O3-SnO2 liquid SnO2-SiO2-ZrO2 amorphous phases, densification mullitisation through phase and, mitigated volatilisation (Zr1-xS...

Digital light processing (DLP) can produce small series ceramic parts with complex geometries and tiny structures without the high cost of molds usually associated traditional processing. However, availability feedstock different ceramics for technique is still limited. Mullite-zirconia composites are refractory materials diverse applications, nevertheless, their 3D printing has never been repo...

The selection of raw materials affects the rate of batch-to-glass conversion. In all-electric melters, foam under the batch blanket limits the heat flux from the molten glass, thus slowing the rate of melting. Our study, in which we compare the melting behaviors of three batches formulated to vitrify high-alumina high-level waste, shows that a slowly dissolving refractory component can cause ex...

Due to their small size, extremely fast response, and low cost, refractory metallic thin film thermocouples (TFTCs) are well suited for the surface temperature measurement of hot components. In this study, PtRh films with different amounts of Rhodium (10% and 13%) were deposited with direct current magnetron sputtering and annealed at different temperatures in air. The chemistry, microstructure...

plasters are produced from a light refractory material, mainly mgo (m.p. 2800ºc), a binder, and a void forming substance for insulating purposes. different oxides from the slag penetrate into these voids and provide low melting-point phases suchasrhodonite (mnsio3) (1290ºc), tephorite (mn2sio4) (1345ºc), merwinite (ca3mgsi2o8) (1575ºc), monticellite (camgsio4) (1490ºc), and enstatite (mgsio3) (...
