Both monolithic and multilayer mullite-alumina ceramic composites dedicated to ballistic applications were produced by uni-axial pressing tape casting before being sintered at 1510 °C. The compositions combining andalusite kaolin in addition α-alumina exhibit the more promising mechanical properties, reaching performances of pure alumina. However, for a given bulk density value, significant imp...

The relations between Barrovian- and Buchan-type metamorphic series in the Chinese Altai remain obscure, hence a representative region of central part was investigated to address this issue, using combined microstructural, petrological geochronological methods. In region, Barrovian-type garnet, staurolite, kyanite sillimanite zones are locally overprinted by andalusite- cordierite-bearing domai...

the formation of atoll garnet in the ardara aureole, nw ireland, is discussed using the textural, chemical and electron backscatter diffraction (ebsd) data. textural evidence suggests the possibility of incipient of garnet replacement from the core. in addition, the presence of staurolite and andalusite in the core of small atoll garnets as well as the occurrence of sillimanite in the core of l...

Although mullite–zirconia composites made from zircon, alumina, and andalusite meet the requirements for many refractory applications, little effort has been to transfer these bonding phase (the ‘matrix’) of bricks. In this paper, we investigate how could be achieved through better control secondary oxides. The high temperature phases were simulated with thermodynamic software linked microstruc...
