摘要： Silazanes and related compounds are prepared by (a) providing a precursor containing at least one Si--N bond, cleaving an Si--N bond in the precursor in the presence of hydrogen or a hydrogen donor, and reacting the cleavage product with a second cleavage product or with a compound containing an Si--H bond, an N--H bond, or both, to produce an initial silazane product having at least one newly formed Si--N bond or (b) providing one or more reactants which contain an Si--H bond and an N--H bond, and causing reaction to occur between the two bonds in the presence of a transition metal catalyst to form an initial silazane product having newly formed Si--N bonds. Further products may result from additional reaction of either type. Novel compounds, including siloxazanes and high molecular weight polysilazanes, are provided. The compounds may be pyrolyzed to yield ceramic materials such as silicon nitride, silicon carbide and silicon oxynitride. In a preferred embodiment, substantially pure silicon nitride and articles prepared therefrom are provided. Fibers, coatings, binders, and the like may be prepared from the novel materials.

摘要： Production of carbide shapes of silicon, titanium or vanadium by reaction of carbon with the metal in liquid phase such being carried out by heating a mixture of particles of carbon and particles of the metal rapidly to the melting point of the metal, thereby minimizing solid state reaction, and holding at a temperature and for a time sufficient to cause reaction. The metal and carbon particles are about 0.05 to 10 mm in diameter. An organic binder is used which volatilizes or dissociates upon heating.

摘要： Protective coatings are applied to substrate metals by coating the metal surface, e.g. by dipping the substrate metal in a molten alloy of the coating metals, and then exposing the coating at an elevated temperature to an atmosphere containing a reactive gaseous species which forms a nitride, a carbide, a boride or a silicide. The coating material is a mixture of the metals M.sub.1 and M.sub.2, M.sub.1 being zirconium and/or titanium, which forms a stable nitride, carbide, boride or silicide under the prevailing conditions. The metal M.sub.2 does not form a stable nitride, carbide, boride or silicide. M.sub.2 serves to bond the carbide, etc. of M.sub.1 to the substrate metal. Mixtures of M.sub.1 and/or M.sub.2 metals may be employed. This method is much easier to carry out than prior methods and forms superior coatings. Eutectic alloys of M.sub.1 and M.sub.2 which melt substantially lower than the melting point of the substrate metal are preferred.

摘要： A method and apparatus for forming polycrystalline diamond composites comprising forming a preform shape with at least 60 volume percent diamond, and then depositing diamond by chemical vapor methods. The chemical vapor deposition may be chemical vapor infiltration with a thermal gradient applied through a thickness of the preform shape. The thermal gradient may be selected to provide sufficient temperature variation to produce a diamond layer on a hot surface of the preform shape but is too low to produce a diamond layer on a hot surface of the preform shape but is too low to produce a diamond layer on a cooler surface of the preform shape. Diamond may be deposited on the surface of a preform shape that is subsequently removed.

摘要： Process for applying a protective coating to a metal substrate which provides a thermal barrier and a barrier against oxidation of the substrate. The coating material is a mixture of (1) zirconium and/or hafnium and (2) a metal such as nickel which does not form a stable oxide at a high temperature in an atmosphere having a very low concentration of oxygen. The coating is subjected to such conditions to produce an outer oxide layer of metal zirconium and/or hafnium and an inner metal layer of the second metal alloyed with one or more components of the substrate. The oxide layer provides thermal and oxidation protection and the inner layer bonds the coating to the substrate.

摘要： Silicon (Si) is cast into thin shapes within a flat-bottomed graphite crucible by providing a melt of molten Si along with a relatively small amount of a molten salt, preferably NaF. The Si in the resulting melt forms a spherical pool which sinks into and is wetted by the molten salt. Under these conditions the Si will not react with any graphite to form SiC. The melt in the crucible is pressed to the desired thinness with a graphite tool at which point the tool is held until the mass in the crucible has been cooled to temperatures below the Si melting point, at which point the Si shape can be removed.
摘要翻译：硅（Si）通过提供熔融Si的熔体以及相对少量的熔融盐，优选NaF，在平底石墨坩埚内铸成薄的形状。所得熔体中的Si形成一个沉淀并被熔融盐润湿的球形池。在这些条件下，Si不会与任何石墨反应形成SiC。坩埚中的熔体用石墨工具压制到所需的薄度，此时工具被保持直到坩埚中的质量已经被冷却到低于Si熔点的温度，此时可以去除Si形状。

摘要： A method of protecting ferrous metal structures from oxidative attack in an aqueous, corrosive, oxidative environment by applying a thin, impervious coating of an oxide of titanium, zirconium, tantalum or niobium (or a mixture of two or more such oxides). The coating is applied as an alloy (preformed or form in situ) of the respective metal and a more noble metal such as nickel, cobalt, copper or iron and the alloy is preferably thermally oxidized under conditions to oxidize the titanium, zirconium and/or niobium without oxidizing the more noble metal, which serves to bind the oxide coating to the substrate. Alternatively the alloy may be applied, and then oxidized by the conditions of use.
