Disclosed are ceramic bodies comprised of composite cordierite-mullite-aluminum magnesium titanate (CMAT) ceramic compositions having high cordierite-to-mullite ratio and methods for the manufacture of same.

High cordierite-to-mullite ratio cordierite-mullite-aluminum magnesium titanate compositions and ceramic articles comprising same

Composite ceramic materials are disclosed herein which comprise two or more crystalline phases, wherein a first crystalline phase comprises a first refractory material having a first melting point, and a second crystalline phase comprises a second refractory material having a second melting point which is lower than the first melting point, and the second crystalline phase comprises large domain sizes of the second refractory material. Articles comprising such a composite ceramic material, such as honeycomb bodies, catalytic substrates, and particulate filters, are also disclosed herein, in addition to methods of manufacture thereof.

Composite ceramic materials, articles, and method of manufacture

Comminuted pre-mixtures for technical ceramics production, and ceramic bodies made therefrom, the comminuted pre-mixtures being comprised of cellulosic components and alumina source components and the bodies being produced by compounding the comminuted pre-mixtures with powdered inorganic components into batch mixtures, adding liquids to the batch mixtures to form plastic batches, forming the plastic batches into shaped bodies, and heating the shaped bodies to form the ceramic bodies.

Compositions and methods for making low thermal expansion ceramic bodies

A doped silica-titania ('DST') glass article that includes a glass article having a glass composition comprising a silica-titania base glass containing titania at 7 to 14 wt. % and a balance of silica, and a dopant selected from the group consisting of (a) F at 0.7 to 1.5 wt. %, (b) BOat 1.5 to 5 wt. %, (c) OH at 1000 to 3000 ppm, and (d) BOat 0.5 to 2.5 wt. % and OH at 100 to 1400 ppm. The glass article has an expansivity slope of less than about 1.3 ppb/Kat 20&#xb0; C. For DST glass articles doped with F or BO, the OH level can be held to less than 10 ppm, or less than 100 ppm, respectively. In many aspects, the DST glass articles are substantially free of titania in crystalline form.

Doped ultra-low expansion glass and methods for annealing the same

Disclosed herein is a ceramic body comprising at least one phase comprising a pseudobrookite-type crystal structure and at least one phase comprising zirconium tin titanate. Also disclosed are porous ceramic honeycomb structures comprising a ceramic body comprising at least one phase comprising a pseudobrookite-type crystal structure and at least one phase comprising zirconium tin titanate and methods of preparing a ceramic body comprising at least one phase comprising a pseudobrookite-type crystal structure and at least one phase comprising zirconium tin titanate.

Low thermal expansion aluminum titanate-zirconium tin titanate ceramics

Low thermal expansion aluminum titanate zirconium tin titanate ceramics

A method of making ceramic articles includes compounding ceramic precursor batch components that include hydrous clay. The hydrous clay includes particle components having a platy geometry. The crystallite size of the platy hydrous clay particle components is greater than a predetermined amount. Controlling such crystallite size can result in reduced shrinkage of green ware during the clay dehydroxylation stage of firing.

Control of clay crystallite size for shrinkage management

A method of making ceramic articles includes compounding ceramic precursor batch components that include hydrous clay. The hydrous clay includes particle components having a platy geometry. The crystallite size of the platy hydrous clay particle components is less than a predetermined amount. Controlling such crystallite size can result in fired ceramic articles with a lower coefficient of thermal expansion and improved thermal shock resistance.

Control of clay crystallite size for thermal expansion management

A ceramic structure which is pollucite-based and has high refractoriness and high resistance to thermal shock. The inventive structure is suitable in high temperature applications such as a filtering particulates from diesel engine exhaust.

Pollucite-based ceramic with low CTE

A method for polishing glass, ceramic, and glass-ceramic surfaces. The method includes exposing the surface to ultraviolet laser radiation under conditions effective to smooth the surface. Methods for polishing glass-ceramic surfaces containing spinel crystals using 193-351 nm radiation of a rare gas halide excimer laser operating at about 150 to about 400 mJ/cm.sup.2 are disclosed. Using the methods of the present invention, surfaces having an R.sub.a of about 4 to about 2 .ANG. are produced.
