Cordierite-mullite refractories
Ceramics International, 1995Abstract This study aims to prepare cordierite-mullite composites to be used as refractories, mainly setters. The cordierite-mullite percentage was kept constant (70:30%). Mullite and cordierite were added in different proportions either as grog or raw materials, fulfilling the above stoichiometric composition.

Cordierite bodies having virtually zero porosity when fired between 1285° and 1325°C. were obtained by using calcined blends of MgCO 3 , talc, and clay; the calcine was combined with raw clay to form the body. These bodies were characterized by low thermal expansion, good mechanical strength,

Dieselpartikelfilter aus Cordierit
MTZ - Motortechnische Zeitschrift, 2008Derzeit kommen bei Pkw mit Dieselmotor meist keramische Partikelfilter aus Siliziumkarbid (SiC) zum Einsatz. Cordierit-Partikelfilter sind zwar gunstiger in der Herstellung und bieten einige zusatzliche technische Vorteile, jedoch fehlte fur die Serienverbreitung bisher eine robuste Regenerationsstrategie, um den Abbrand des Ruses unter allen ...

Synthesis of cordierite and cordierite-ZrSiO4 composite by colloidal processing
Journal of Materials Science, 1994Cordierite 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

Cordierite-ZrO2 and cordierite-Al2O3 composites obtained by sonocatalytic methods
Journal of Non-Crystalline Solids, 1992Cordierite-matrix-based composites were prepared by the sol-gel process involving sonocatalysis during preliminary chemical reactions. ZrO2 and Al2O3 ceramic fibers were employed as reinforcing phases. Sintering was accomplished by hot-pressing techniques.

Development of Carbon Coatings for Cordierite Foams: An Alternative to Cordierite Honeycombs
Langmuir, 2008Cordierite 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 ...

Kinetics of the μ-cordierite crystal nucleation on polished cordierite glass
Journal of Non-Crystalline Solids, 1997Copyright (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 ...
