摘要： Disclosed is a method for fabricating a ceramic material from a preceramic polymer material. The method includes providing a preceramic polymer material that has a preceramic polymer and an electromagnetic radiation-responsive component. The electromagnetic radiation-responsive component is selected from cobalt, titanium, zirconium, hafnium, tantalum, tungsten, rhenium, and combinations thereof. An electromagnetic radiation is applied to the preceramic polymer material. The electromagnetic radiation interacts with the electromagnetic radiation-responsive component to generate heat that converts the preceramic polymer to a ceramic material.

摘要： A composite composed of two principal strengthening compounds and one principal cementing refractory metal that is prepared by combining a suitable binary to senary borides and/or carbides with a unitary to binary principal refractory metal is disclosed. As compared with the conventional sintered cemented carbides, the composite of the disclosure not only possess high hardness and high toughness but also has various ratios of principal components since it is not prepared with equal mole during the process.

摘要： Methods for preparing ceramic matrix composites using melt infiltration and chemical vapor infiltration are provided as well as the resulting ceramic matrix composites. The methods and products include the incorporation of sacrificial fibers to provide improved infiltration of the fluid infiltrant. The sacrificial fibers are removed, such as decomposed during pyrolysis, resulting in the formation of regular and elongate channels throughout the ceramic matrix composite. Infiltration of the fluid infiltrant can then take place using the elongate channels resulting in improved density and an improved ceramic matrix composite product.

摘要： Eutectic cermet materials include at least two carbides and a refractory metal, wherein the carbide is selected from the group of TiC, VC, ZrC, HfC, WC, NbC and TaC, and the refractory metal is tungsten. The disclosed eutectic cermet material prepared is by smelting the carbide and the refractory metal together at a temperature lower than melting temperatures of the carbide and the refractory material. The melting temperature lowered by forming a eutectic composition is to prepare the eutectic cermet materials having a fine lamellar structure. The prepared eutectic cermet materials improve hardness and toughness at use.

摘要： Provided are spherical silicon oxycarbide particle material and manufacturing method thereof, wherein the average particle size is in the range of 0.1-100 μm and having a sphericity of 0.95-1.0.Spherical silicon oxycarbide particle material and manufacturing method thereof are provided as follows. Organotrialkoxysilane is hydrolyzed in a pH 3-6 acetic acid aqueous solution, thereafter an alkaline aqueous solution such as a pH 7-12 ammonia water was added to the obtained hydrolysate. The condensation reaction is performed in an alkaline range to form spherical polysilsesquioxane particles that are spherical silicon oxycarbide precursors that has no melting point or softening point. Sintering was then performed at a sintering temperature of 600-1400° C. under inert atmosphere to obtain spherical silicon oxycarbide particle material.
