Electrical properties and thermal expansion of cordierite and cordierite-mullite materials

Journal of the European Ceramic Society, 2001
Abstract Commercially available cordierite and mullite powders were used to obtain cordierite and composite materials with mullite content up to 65 wt.% by attrition milling, uniaxial pressing and sintering. The employed cordierite powders were the coarse, medium and fine single granulometric fractions and the binary mixtures of them with 30, 50 and ...

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 ...

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.

Zirconia toughened cordierite

Journal of Materials Science, 1990
Zirconia-cordierite ceramic composites were fabricated by the hot pressing of cordierite and zirconia powders at 1400 ° C/20 MPa for 10 min. Both the fracture toughness and fracture strength have been enhanced by the addition of zirconia. Such improvements are due to stress-induced transformation toughening and to the generation of residual stresses ...

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.
