According to the present invention, a dense composite material includes titanium silicide in an amount of 43 to 63 mass %; silicon carbide in an amount less than the mass percentage of the titanium silicide; and titanium carbide in an amount less than the mass percentage of the titanium silicide. In the dense composite material, a maximum value of interparticle distances of the silicon carbide is 40 μm or less, a standard deviation of the interparticle distances is 10 or less, and an open porosity of the dense composite material is 1% or less.

A metal-Si based powder contains a metal-Si based particle including a plurality of crystal phase grains. The crystal phase grains include a crystal phase containing a compound of a metal and Si. The crystal phase grains have an average grain size of, for example, 20 μm or less. The metal-Si based particle has an average particle size of, for example, 5 to 100 μm.

A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a binder and a primary material. The binder is configured to release a secondary material upon heating at or above a conversion temperature. The method also may include heating the fused filament fabricated component to a temperature at or above the conversion temperature to sinter the primary material to form a sintered part and cause the binder to release the secondary material within the sintered part.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.

A ceramic matrix composite has fibers, a ceramic matrix bonded to the fibers, and ceramic particles, distributed throughout the matrix. A method includes mixing a high char ceramic resin precursor with ceramic particles, adding a catalyst to create a mixture, heating the mixture to produce functionalized ceramic particles, and cooling the mixture to produce a resin having functionalized particles.

A thermoelectric conversion material formed of a sintered body containing magnesium silicide as a main component contains 0.5 mass % or more and 10 mass % or less of aluminum oxide. The aluminum oxide is distributed at a crystal grain boundary of the magnesium silicide.

A composite article comprises a substrate, the substrate comprising a silicon containing material and an additive comprising boron nitride nanotubes.

A method for manufacturing a part made of composite material includes injecting into a fibrous texture a slurry including at least one powder of refractory ceramic particles suspended in a liquid phase, filtering the liquid phase of the slurry and retaining the powder of refractory ceramic particles inside the texture so as to obtain a fibrous preform loaded with refractory ceramic particles, densifying the fibrous texture by treatment of the refractory ceramic particles present in the fibrous texture in order to form a refractory matrix in the texture. The method further includes, before injecting the slurry under pressure, pre-saturating the fibrous texture with a carrier fluid consisting in injecting into said texture a carrier fluid.
