    • This invention relates to a method for producing a self-supporting body comprising the steps of:(a) forming a permeable mass comprising at least one solid-phase oxidant selected from the group consisting of the halogens, sulphur and its compounds, metals, metal oxides other than the silicates, and metal nitrides other than those of boron and silicon;(b) orienting said permeable mass and a source of said parent metal relative to each other so that formation of said oxidation reaction product will occur into said permeable mass;(c) heating said source of parent metal to a temperature above the melting point of said parent metal but below the melting point of said oxidation reaction product to form a body of molten parent metal;(d) reacting said body of molten parent metal with said at least one solid-phase oxidant at said temperature to permit said oxidant at said temperature to permit said oxidation reaction product to form; and(e) maintaining at least a portion of said at least one oxidation reaction product in contact with and between said molten parent metal and said solid-phase oxidant at said temperature to progressively draw molten parent metal through said oxidation reaction product towards said solid-phase oxidant to permit fresh oxidation reaction product to continue to form at an interface between said solid-phase oxidant and previously formed oxidation reaction product that has infiltrated said permeable mass.

    • Self-supporting bodies are produced by reactive infiltration of a parent metal into a boron nitride material typically resulting in a body comprising a boron-containing compound, a nitrogen-containing compound and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron nitride, to produce a composite by reactive infiltration, which composite comprises a matrix which embeds the filler material. The matrix, in a composite body containing filler material, comprises one or more of metal, a boron-containing compound and a nitrogen-containing compound. The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal and/or porosity. The mass to be infiltrated can be contained within a refractory vessel having a venting means included therein.
    • 通过将母体金属反应性渗透到氮化硼材料中而产生自支撑体,通常产生包含含硼化合物,含氮化合物和金属的体。 待渗透的物质可以包含一种或多种与氮化硼混合的惰性填料,以通过反应性渗透产生复合材料,该复合材料包括嵌入填料的基质。 含有填料的复合体中的基体包含一种或多种金属,含硼化合物和含氮化合物。 可以改变或控制反应物和工艺条件的相对量,以产生包含不同体积百分比的陶瓷,金属和/或孔隙的体。 待渗透的物质可以包含在其中包括排气装置的耐火容器中。
