摘要： An apparatus for bonding a first carbon composite to a second carbon composite through a reactant layer includes a housing, and a pair of conductive press plates electrically isolated from the housing. The press plates are adapted to position the two parts to be bonded with a reactant layer therebetween. The press plates are subjected to an electrical potential and a clamping force, sufficient to initiate a combustion reaction that creates a molten ceramic to bond together the carbon-carbon composites.

摘要： Boron carbide ceramics produced by spark sintering methods have more desirable mechanical properties than conventionally produced carbides. The boron carbide ceramics include amorphous boron, amorphous carbon, and Al2O3 powder as a sintering aid. The boron carbides may also contain a carbon nano fiber in a nearly homogeneously dispersed state. The sintered compact has a relative density of a boron carbide ceramic of approximately not less than 99%. The boron carbide ceramics are prepared preferably by subjecting a mixed powder of the starting raw materials and the carbon nano fiber to simultaneous synthesis and sintering using the spark plasma sintering method

摘要： This invention relates to a ceramic and a cermet each having a second phase for improving toughness via phase separation from a complete solid-solution phase and to a method of preparing them. The ceramic and the cermet may have the second phase phase-separated from the complete solid-solution phase, thereby easily achieving a great improvement in toughness and exhibiting other good properties including high strength, consequently enabling the manufacture of high-strength and high-toughness cutting tools, instead of conventional WC—Co hard materials.

摘要： A method for producing cubic boron nitride in which hBN is held in the presence of a catalyst substance under conditions in which cBN remains thermodynamically stable, to thereby cause hBN to undergo a phase transition to form cBN, wherein the catalyst substance contains a lithium source, a magnesium source, and a carbon source. The performance of cBN is improved even though phase transition ratio from hBN to cBN is increased.

摘要： The invention relates to a method for production of an object with an at least partly silicon carbide structure from a blank of a carbon-containing material, wherein, in a first step, the object made from the carbon-containing material is produced essentially in the desired end form and/or end size, the object made from the carbon-containing material is then at least partly enveloped in a carbon-rich silicon dioxide granulate and then fired at least once in the envelope in a protective gas atmosphere such that the silicon dioxide granulate gives off gas containing silicon carbide which diffuses into the object and the carbon-containing material is completely or partly converted into silicon carbide. The invention further relates to a method for producing an object with an at least partly silicon carbide structure from a blank made from a carbon-containing material or a porous silicon carbide in which the pre-made object is infiltrated with a precursor sol containing silicon and carbon and fired at least once in a protective gas atmosphere at a firing temperature for carrying out a carbothermal reduction, wherein the infiltrated precursor sol gives off a gas containing silicon carbide which converts the material of the object partly or completely into silicon carbide.

摘要： The present invention includes methods for simultaneously producing, within a single container, two or more sections of high density carbon foam materials of defined shape. A method used to prepare high density carbon foam sections may involve heating a comminuted agglomerating bituminous coal bed, that is at least partially divided into two or more sections by the use of partitions within the coal bed, to an elevated temperature sufficient to result in the coal particles softening and melting together to form sections of a generally homogeneous, continuous, open cell carbon material. The sections of homogeneous open cell carbon material are then maintained at an elevated temperature for a period of time sufficient to substantially reduce or essentially eliminate the plastic properties of the bituminous coal. As desired, the resultant high density carbon foam sections may be cooled to essentially ambient temperatures or immediately or subsequently heated to elevated temperatures as great as about 3200° C., followed by cooling.

摘要： Adsorbed gaseous species and elements in a carbon (C) powder and a graphite crucible are reduced by way of a vacuum and an elevated temperature sufficient to cause reduction. A wall and at least one end of an interior of the crucible is lined with C powder purified in the above manner. An Si+C mixture is formed with C powder purified in the above manner and Si powder or granules. The lined crucible is charged with the Si+C mixture. Adsorbed gaseous species and elements are reduced from the Si+C mixture and the crucible by way of a vacuum and an elevated temperature that is sufficient to cause reduction but which does not exceed the melting point of Si. Thereafter, by way of a vacuum and an elevated temperature, the Si+C mixture is caused to react and form polycrystalline SiC.
