    摘要： The present invention is directed to a highly pure, partially stabilized, fibrous zirconia composite for use as thermal insulation in environments where temperatures up to about 2000.degree. C. are utilized. The composite of the present invention is fabricated into any suitable configuration such as a cone, cylinder, dome or the like by vacuum molding an aqueous slurry of partially stabilized zirconia fibers into a desired configuration on a suitably shaped mandrel. The molded fibers are infiltrated with zirconyl nitrate and the resulting structure is then dried to form a rigid structure which may be removed and placed in a furnace. The structure is then heated in air to a temperature of about 600.degree. C. for driving off the nitrate from the structure and for oxidizing the zirconyl ion to zirconia. Thereafter, the structure is heated to about 950.degree. to 1,250.degree. C. to fuse the zirconia fibers at their nexi in a matrix of zirconia. The composite produced by the present invention is self-supporting and can be readily machined to desired final dimensions. Additional heating to about 1800.degree. to 2000.degree. C. further improves structural rigidity.

    摘要翻译： 本发明涉及一种高纯度，部分稳定的纤维状氧化锆复合材料，用于在高达约2000℃的温度下使用的绝热材料。 通过将部分稳定的氧化锆纤维的含水浆料真空成型为合适形状的心轴上所需的构型，将本发明的复合材料制成任何合适的构型，例如锥体，圆筒，圆顶等。 模制的纤维用硝酸氧锆渗透，然后将所得结构物干燥以形成可以去除并置于炉中的刚性结构。 然后将结构在空气中加热到约600℃的温度，以从结构中排除硝酸盐，并将氧化锆氧化成氧化锆。 此后，将结构加热至约950℃至1250℃，以将氧化锆纤维在其氧化锆基体中熔化。 由本发明生产的复合材料是自支撑的并且可以容易地加工成所需的最终尺寸。 另外加热至约1800°至2000℃，进一步提高了结构刚度。

    摘要： A process of producing a uniform fiber dispersion involves the use of an in-line dispersing chamber to provide an average fiber dwell time of only about ten minutes and less. The chamber is provided with a plurality of weedless, nonthrusting impellers that generate regions of reduced pressure and flow disruptive turbulence of high intensity, the turbulence being of sufficient intensity to rapidly open fiber bundles and disperse the individual long fibers during said dwell time within said chamber. The process produces a machine-made light weight glass fiber web material of exceptionally uniform fiber distribution. The web is comprised of micron diameter glass fibers having a fiber length of about 1/4 inch or more and a basis weight of about 5-30 grams/square meter. The web material exhibits an isolated multi-fiber defect count of less than 10 per 100 square feet and a visually perceptible overall uniform fiber distribution essentially devoid of "cloud effect" fiber density variations.
