  • Production of cordierite ceramic by aqueous tape

    2008-3-3 · 1.. IntroductionTape casting is widely used in the industry for making large thin sheets of ceramic materials for the fabrication of ceramic substrates, multilayer products, piezoactuators, sensors, etc. (Hotza and Greil, 1995, Bitterlich et al., 2002).Typically, during tape casting, slip consisting of the ceramic powder dispersed in a solvent, with the addition of dispersants, binder and ...

  • Processing of microcellular cordierite ceramics from a ...

    2006-4-1 · A novel processing route for producing microcellular cordierite ceramics has been developed. The proposed strategy for making the microcellular cordierite ceramics involves three steps: (i) fabricating ceramic-filled preceramic foams by heating a mixture of polysiloxane, expandable microspheres, talc, and alumina in a mold, (ii) cross-linking the foamed body, and (iii) transforming the body ...

  • US3940255A - Process for making cordierite glass

    A cordierite-type glass-ceramic and a process for its preparation are disclosed, characterized in that a nucleating agent in a small amount is added preferably to a glass batch capable of producing cordierite. The nucleating agent aids in forming a glass-ceramic refractory of relatively large amounts of crystalline cordierite. The melt is quenched and ground to an average particle size no ...

  • Cordierite Ceramics - Digitalfire

    Although cordierite is available as a powder, when we use the term we are generally talking about ceramic that went into the kiln as ordinary composite of mineral powders but emerges as a solid cordierite crystalline matrix (grown by the firing process tuned to its needs). Cordierite makes the ceramic manufacture of products like catalytic ...

  • What is Cordierite? | Materials Science | Corning

    This synthetic cordierite could be rapidly heated and cooled, while barely changing dimensions, making it very thermal shock resistant. Corning’s take on cordierite lent itself well to a modified extrusion manufacturing process, allowing the creation of a thin-walled cell structure, with thousands of parallel walls, to create a honeycomb-like ...

  • Method for producing cordierite-based ceramic

    What is claimed is: 1. A method for producing a cordierite-based ceramic honeycomb structure, comprising steps of: kneading powdered cordierite raw material together with an extruding aid to prepare a material batch; extruding the material batch to obtain a formed body; and drying and then firing the formed body, to produce the honeycomb structure with cordierite as the major component in the ...

  • Characterization of cordierite-mullite ceramics prepared ...

    2013-5-20 · has helped sintering process. However, due to fact that the natural mineral is not abundant or pure enough, advanced ceramics based on cordierite for special applications have to be synthesized form the ternary oxide system MgO-Al 2 O 3-SiO 2. This system is characterized by two main minerals; cordierite (2MgO·2Al 2 O 3 ·5SiO 2) and mullite ...
