Synthesis of cordierite powder from talc, diatomite and alumina

A cordierite powder was synthesized from a batch composition of talc, diatomite and alumina. Sintered samples of the synthesized cordierite were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA), and Rietveld analysis. The XRD analysis showed hexagonal or a-cordierite (indialite) as a major phase along with MgAl2O4 spinel and cristobalite as secondary phases in the s...

"Very High Alumina Basalt":

The proposal by Hubbard et al. (1) that "Very High Alumina basalt" ("VHA basalt") may represent an important primary lunar magma type neglects consideration of certain well-characterized high-magnesium highland rocks, among them spinel troctolite from Luna 20 (2) and Apollo 16 samples (3) and dunite from Apollo 17 samples (4), and the possibility that "VHA basalt" may in fact have originated by...

Investigation on Mechanism of Cordierite Formation from Nano Silica-Magnesium chloride-Reactive Alumina

Cordierite ceramics are used as refractory materials and kiln furnaces tools due to their very low coefficient of thermal expansion, high corrosion resistance and excellent thermal shock resistance. The aim of the present work was to synthesis of cordierite with raw materials including nano silica, magnesium chloride and reactive alumina. The synthesis procedure is done at solid state. Mechanis...

Ultrasonic Velocity Measurements in Alumina-zirconia Ceramic Composite System

Among novel structural materials, composites are attractive because they combine the properties of two o more individual components. As an important example, in alumina-zirconia ceramic composite system, the incorporation of α-Al2O3 into stabilized zirconia increases significantly the mechanical and thermal properties. In this work an alumina-zirconia ceramic composite have been prepared with d...

PREPARATION AND PROPERTIES OF NANOPHASE (Ce, Zr, Pr)O2-DOPED ALUMINA COATING ON CORDIERITE CERAMIC HONEYCOMB FOR THREE-WAY CATALYSTS

Nanophase (Ce, Zr, Pr)O2-doped alumina coatings were prepared by impregnating the cordierite ceramic honeycomb in the sol or in the slurry of already calcined powder, respectively. The effects of preparation methods on the crystal phase, texture, oxygen storage capacity (OSC), reducibility, surface morphology and thermal stability of coatings were investigated by X-ray diffraction (XRD), the Br...
