Disclosed herein is a method of: placing between a cooling element and an opposing surface a slurry of: a dielectric powder containing barium titanate, a dispersant, a binder, and water; maintaining the cooling element at a temperature below the opposing surface to cause the formation of ice platelets perpendicular to the surface of the cooling element and having the powder between the platelets; subliming the ice platelets to create voids; sintering the powder to form the dielectric material; and filling the voids with the polymeric material. The process can produce a composite having: a sintered dielectric material of barium titanate and platelets of a polymeric material embedded in the dielectric material. Each of the platelets is perpendicular to a surface of the composite.

A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.

Methods for laser additive manufacture are disclosed in which a plurality of powder layers (48, 50 and 52) are delivered onto a working surface (54A) to form a multi-powder deposit containing at least two adjacent powders layers in contact, and then applying a first laser energy (74) to a first powder layer (48) and a second laser energy (76) to a second powder layer (52) to form a section plane of a multi-material component.

An object of the present invention is to provide a building large porcelain panel that prevents the efflorescence.

As the solutions, a building large porcelain panel according to the present invention is formed by kneading a raw material formulation containing, as a main material, a refractory aggregate, a glassy raw material, and cement, and subjecting the raw material formulation to molding and then firing, wherein the building large porcelain panel has a Na.sub.2O content of 1 mass% or less in an entire chemical-component composition of the building large porcelain panel fired. In addition, the building large porcelain panel has a Na2O content of 1% or less and containing 0.5 to 7% of BaO and 0.5 to 8% of B.sub.2O.sub.3 (12% or less of the BaO and the B.sub.2O.sub.3) at mass-based chemical component values.

A second mold is placed on a planar surface of a first mold to form a first mold cavity, which is filled with a first material slurry containing a first material powder and the molded slurry is caused to set, thereby forming a first molded part on the planar surface of the first mold. A third mold is placed on the planar surface of the first mold from which the second mold is removed and on which the first molded part is formed, thereby forming a second mold cavity. The second mold cavity is filled with a second material slurry which contains a second material powder different from the first material powder so as to mold the slurry in contact with the first molded part. The molded slurry is caused to set, thereby forming a second molded part on the planar surface of the first mold.

The invention concerns an article (20) formed of a ceramic matrix composite structure having a plurality of ceramic fiber layers (22) and a binder material (24) interspersed throughout said layers. The ceramic matrix composite material may be sintered. The ceramic fiber layers undulate relative to one or more outer surfaces (38;40) of the article. Thus support features (48) within the article are able to share a load in use between a plurality of layers. The invention may be suited to engine components such as turbine seal segments in a gas turbine engine.
