摘要： A dense ceramic workpiece is made by a process of combining a powdered (312) component, e.g., Ti3SiC2, with a powdered component that is soluble in the (312) component, e.g., TiSi2 in Ti3SiC2, forming the mixture into a green body, heating the green body under pressureless sintering conditions to a temperature above a point at which a liquid is formed but below the melting point of the (312) compound to yield a dense ceramic workpiece, and thereafter cooling the dense (312) ceramic workpiece.

摘要： The present invention is directed to compositions comprising free standing and stacked assemblies of two dimensional crystalline solids, and methods of making the same. Typically, two-dimensional, 2-D, free-standing crystals exhibit properties that differ from those of their three-dimensional, 3-D, counterparts. Currently, however, there are relatively few materials which can be described as 2-D, atomically-scaled layered solids. Clearly the most studied freestanding 2-D material is graphene, but other materials include hexagonal BN, certain transition metal oxides, hydroxides, and silicates, including clays, S2N, MoS2 and WS2 are also known.

摘要： A ceramic material is surface treated by contacting the surface of a 312 ternary ceramic material with a surface-modifying compound selected from carburization agents, silicidation agents, nitridation agents and boronization agents, at an elevated temperature of at least about 600 °C for a period of time sufficient to provide a surface reaction layer of at least about one micron in thickness in the surface-treated material, preferably having a surface hardness in excess of about 6 GPa. A product made by the method of this invention is also disclosed having a surface hardness in excess of about 6 GPa, preferably at least about 10 GPa.
