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...

Lightweight corundum-mullite thermal insulation materials were successfully prepared by microwave sintering at low temperature. The effects of temperatures, PMMA microspheres and SiC particles on structure properties as-prepared investigated. became a hot spot under the action field, these local high temperature areas promoted formation growth mullite whiskers. burn out, leaving pores which cou...

Undesired solid precipitation in coal slag at high temperatures can cause serious blockages, or even the shutdown of gasifiers, due to a rapid increase viscosity. In this study, behaviors from different primary phases and under atmospheres were both experimentally theoretically investigated. Our results demonstrated that viscosity phase mullite was strongly influenced by atmosphere typical tapp...

Kaolin is a clay mineral that has found its huge use in electrical insulation. In power industries, mullite insulators plays vital role during electric transmission. The transformation of kaolin to via sintering method was carried out by varying the temperature heating at interval from . mass observed have changed until complete took place 11500C. dielectric strength (breakdown voltage) analyse...

Alumina, mullite, and cordierite powder were added to a whiteware porcelain slurry sintered at 1280 °C investigate the correlation between composition strength. The X-ray diffraction patterns of bodies show that no new phase was formed, material remained intact. Except for sample group which added, strength increased as additive content increased. A Rietveld quantitative analysis indicated amor...
