Copper-Cordierite Cosintering

Materials Science and Engineering: A, 1989
The use of a sol-gel processed cordierite precursor sinterable about 900 °C allows cosintering of the copper and the ceramic. A strong bonding between the copper film and the cordierite substrate can be achieved through an eutectic bonding technique. Three types of interfaces have been studied by EPMA, ESCA and SEM: (a) cosintered in hydrogen, leading ...

Synthesis of cordierite and the technology of cordierite-containtng articles

Refractories, 1983
Studies were made of the synthesis of cordierite from natural materials (talc, kaolin, and alumina) in the presence of various magnesium-containing additives.

slip casting of cordierite and cordierite– mullite materials

Journal of the European Ceramic Society, 1998
Abstract The obtention of cordierite and cordierite–mullite ceramics by slip casting is studied. Aqueous slips with solids contents up to 65 wt% were used. The effect of the deflocculant content and the mixing time on the rheological behavior was studied, showing always a shear thickening behavior, which can be deletereous for demolding and handling.

Development of Carbon Coatings for Cordierite Foams:  An Alternative to Cordierite Honeycombs

Langmuir, 2008
Cordierite foams were prepared by replication of polyurethane foams and were coated with three types of carbon xerogels. The dip coating and synthesis conditions were optimized, and the coated foams were characterized exhaustively. The composition of the starting solution, coat loading, and carbonization temperature are the most important parameters ...

Synthesis of cordierite and cordierite-ZrSiO4 composite by colloidal processing

Journal of Materials Science, 1994
Cordierite powder of high purity and cordierite-ZrO2 composite powder were synthesized by colloidal processing. Cordierite was synthesized by calcining a precursor gel obtained by gelation and coprecipitation of AlOOH sol, SiO2 sol and Mg(NO3)2. The calcination temperature affected the constituent phases in the powders. The phase assemblage in calcined

Energetics of hydration of cordierite and water barometry in cordierite-granulites

Contributions to Mineralogy and Petrology, 1985
The Gibbs free energy and volume changes attendant upon hydration of cordierites in the system magnesian cordierite-water have been extracted from the published high pressure experimental data at \(P_{{\text{H}}_{\text{2}} {\text{O}}} \)=Ptotal, assuming an ideal one site model for H2O in cordierite.

Surface nucleation of μ-cordierite in cordierite glass: thermodynamic aspects

Thermochimica Acta, 1996
Abstract The heterogeneous nucleation rate of μ-cordierite at the surface of cordierite glass (2MgO·2Al2O3·5SiO2) is discussed in terms of classical nucleation theory (CNT). Calculations are based on experimental viscosity data and estimates of the melting temperature and melting enthalpy of μ-cordierite from calorimetric measurements.

The Polymorphism of Cordierite

Journal of the American Ceramic Society, 1953
During the course of a broader investigation on the cordierite‐spodumene join in the system Li 2 O–MgO–Al 2 O 3 –SiO 2 , a clearer picture of the relationships between the ...

Kinetics of the μ-cordierite crystal nucleation on polished cordierite glass

Journal of Non-Crystalline Solids, 1997
Copyright (c) 1997 Elsevier Science B.V. All rights reserved. Nucleation of μ-cordierite crystals (2MgO.2Al 2 O 3 .5SiO 2 ) on the polished surface of cordierite glass was investigated by optical microscopy. The time dependencies of the number of crystals were calculated from the crystal size distributions over a wide temperature range (850-1008°C ...
