Catalytic composition and structures made thereof
Methods use a catalytic composition built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is used for catalytic or ion exchange applications. The catalytic structures have excellent mechanical, physicochemical and catalytic properties.
CERAMIC HONEYCOMB BODY FOR LIGHTWEIGHT STRUCTURES AND CORRESPONDING PRODUCTION METHOD
A honeycomb body made of a composite material for fire-resistant lightweight structures including honeycomb cells having a cross section is provided. The cell walls of the honeycomb cells are produced from a composite material. The composite material has at least one carrier, for example a woven fabric or a laid fabric made of fibers, and a matrix into which the carrier is embedded. The matrix includes a silicon-based ceramic material, of which the proportion by mass in the matrix along the cell walls is at least 30 wt. %. A method for producing such a ceramic honeycomb body and a honeycomb tube as an intermediate product for the same are also provided. A flat semi-finished product as a curable intermediate product for the production of fire-resistant fiber composite lightweight structures, which has a matrix mixture including dispersed silicon particles, is also provided.

HONEYCOMB STRUCTURE AND METHOD FOR PRODUCING HONEYCOMB STRUCTURE
A honeycomb structure including a plurality of porous honeycomb block bodies bound via joining material layers A. Each of the porous honeycomb block bodies includes a plurality of porous honeycomb segments bound via joining material layers B, each of the porous honeycomb segment includes: partition walls that defines a plurality of cells to form flow paths for a fluid, each of cells extending from an inflow end face that is an end face on a fluid inflow side to an outflow end face that is an end face on a fluid outflow side; and an outer peripheral wall located at the outermost periphery. At least a part of the joining material layers A has higher toughness than that of the joining material layers B.
METHOD FOR PRODUCING CERAMIC HONEYCOMB STRUCTURE
A method for producing a ceramic honeycomb structure including: plugging ends of cells on one of a first end face side and a second end face side in each of the cells of a ceramic honeycomb formed body that includes partition walls defining the cells extending from the first end face to the second end face; placing the ceramic honeycomb formed body on a shelf board with the first end face facing downward; arranging at least one lid member on the second end face of the ceramic honeycomb formed body so as to completely cover the second end face; and placing the ceramic honeycomb formed body together with the shelf board and the lid member in a firing furnace and firing the ceramic honeycomb formed body.
High capacity structures and monoliths via paste imprinting
The disclosure relate generally to structures, forms, and monoliths, and methods of preparing the same. This disclosure can produce uniform structured passageways or channels of active material, including adsorbent or catalyst, by imprinting or molding features into a paste on a support that can be subsequently assembled into a gas or liquid treating structure, i.e. a monolith. The paste, which can include an active material, binder, and other potential additives, can be applied to the support or pushed through a support (as in a mesh) as a thin film. The paste can be imprinted, stamped, shaped or otherwise handled to give features of desired height, shape, width, and positioning. When stacked or rolled, the features of one layer contact a subsequent layer, which seal to form passageways. The resulting structure can have high cell-density (>1000 cells per square inch) and a large volume fraction of active material.
Ceramic composite structures and processing technologies
Methods, systems, and processes are used to prepare novel ceramic composite structures that are strong, durable, light-weight, high performance and suitable for a myriad of industrial applications, including, but not limited to, ceramic plates of material suitable for use as ballistic armor. The low manufacturing costs of the processes disclosed provide cheaper, faster ways of producing ceramic matrix composites at lower temperatures and allow for the existence of composite materials and structures which currently are not available.

Composite ceramics and ceramic particles and method for producing ceramic particles and bulk ceramic particles
Methods for producing Polymer Derived Ceramic (PDCs) particles and bulk ceramic components and compositions from partially cured gelatinous polymer ceramic precursors and unique bulk composite PDC ceramics and unique PDC ceramic particles in size and composition. Methods of making fully dense PDCs over approximately 2 m to approximately 300 mm in diameter for applications such as but not limited to proppants, hybrid ball bearings, catalysts, and the like. Methods can include emulsion processes or spray processes to produce PDCs. The ceramic particles and compositions can be shaped and chemically and materially augmented with enhancement particles in the liquid resin or gelatinous polymeric state before being pyrolyzed into ceramic components. Nano-sized ceramic particles are formed from the green body produced by methods for making bulk, dense composite ceramics. The resulting ceramic components have a very smooth surface and are fully dense, not porous as ceramic components from the sol-gel process.
