A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.

A method of fabricating a fiber preform filled with refractory ceramic particles, includes placing a fiber texture including refractory ceramic fibers in a mold cavity; injecting a slip including a powder of refractory ceramic particles present in a liquid medium, the slip being injected into the pores of the fiber texture present in the mold cavity, injection being performed through at least a first face or a first edge of the fiber texture; and draining the liquid medium of the slip that has penetrated into the fiber texture through the porous material part, the draining being performed at least through a second face or a second edge of the fiber texture different from the first face or the first edge, the porous material part also serving to retain the refractory particle powder in the pores of the fiber texture to obtain a fiber preform filled with refractory particles.

A method of manufacturing a wafer mounting table according to an embodiment includes: (a) a step of loading a ceramic slurry containing a ceramic powder and a gelling agent into opening portions of a metal mesh, inducing a chemical reaction of the gelling agent to gelate the ceramic slurry, and then performing degreasing and calcining to prepare a ceramic-loaded mesh; (b) a step of sandwiching the ceramic-loaded mesh between a first ceramic calcined body and a second ceramic calcined body obtained by calcining after mold cast forming so as to prepare a multilayer body; and (c) a step of hot press firing the multilayer body to prepare the wafer-receiving table.

Disclosed are methods for forming boron nitride-containing aggregates that exhibit improved wear by attrition, and resulting filled polymers that exhibit significantly improved thermal conductivity. The boron nitride-containing aggregates are prepared according to a method that includes wet granulating boron nitride powder with a granulation solution to form wet boron nitride-containing granules; and drying the wet boron nitride-containing granules to cause evaporation of solvent in the granulation solution, thereby forming boron nitride-containing granules. Sintering achieves the desired boron nitride-containing aggregates.

In-line inspection and control system to in-situ monitor an extrudate during extrusion. A light beam illuminates a line on the outside circumference of the extrudate skin recording the curvature. A master profile of the illuminated defect-free skin is recorded and compared to successive monitoring of the illuminated skin. Differences from the comparison indicate skin and/or shape defects. A real-time feedback to automatically adjust process control hardware reduces or eliminates the skin and shape defects based on the monitoring and comparison.

A method of forming a structure comprising a continuous fiber material comprises continuously feeding, through a continuous fiber nozzle assembly of an additive manufacturing tool, a feed material comprising a continuous fiber material and a thermoset resin material, heating or cooling the feed material to maintain a temperature of the feed material to a temperature sufficient to tackify the feed material and at least partially cure the feed material and initiate adhesion of the feed material on a build platform or a previously formed portion of a structure, and moving the continuous fiber nozzle assembly in three dimensions while depositing the feed material on the build platform or the previously formed portion of the structure to form the structure comprising the continuous fiber material extending in three dimensions. Related methods of forming a composite structure, and related tools for additively manufacturing a structure are disclosed.
