A process to produce dense nanocrystalline composites such as ceramic bodies, coatings and multi-layered devices with uniform microstructure is disclosed. The invention utilizes sol-gel solutions to reduce agglomeration of nanocrystalline powders in the production of “green bodies” or intermediate products. This novel use of sol-gel solutions also reduces grain growth and porosity in products during sintering. In finished products, final grain sizes are typically less than 100 nm with densities of the final products approaching 99.5% of theoretical densities. In addition, sintering temperatures required are lower than those in conventional methods, typically less than 1,100° C. While FIG. 1 shows one application of this novel process, this invention has wide application in the manufacture of many other products, particularly for composite coatings and in the production of nanodevices.

A travel bag fabricated of flexible material such as nylon and is combined with a specialized rigid support to form combination. The support is configured to protect portions of the bag which are subject to high wear and tear during normal use. In addition, the support is formed to receive and hold wheels therein which facilitate transportation of the bag. The support is constructed of a high impact rigid material such as plastic to resist wear due to friction and impact which may accompany a bag in use. The support is specially arranged to cooperate with the flexible portion of the bag. The shape of the support tends to defend the corners of the bag against particular wear. The flexible main portion and the support portions are affixed together.

A folding table is comprised of a platform connected by hinges to mounting brackets that partially wrap around the vertical supports of a handrail. Slits extend down from the upper edges of the brackets to mate with slits extending up from the lower edges of locking plates on an opposite side of the vertical supports. One of the mounting bracket is a vertically elongated bracket. A folding diagonal brace comprised of upper and lower braces is connected between a lower side of the platform and the elongated bracket. A lower pin at the lower end of the upper brace is positioned through a longitudinal slot in the lower brace. An upper pin on the upper brace is positioned in a coiled slot at an upper end of the lower brace when the platform is fully raised and the diagonal brace is straightened.

The invention provides a preparation method for promoting to sinter zirconium boride or zirconium carbide ceramics by using reaction aids. Two-phase sintering aids capable of being reacted, namely Zr powder and C powder, or Zr powder and B4C powder, are added, and a material is promoted to be compact and crystals of a matrix are inhibited from growing by zirconium carbide/zirconium boride second phase particles with higher sintering activity, which are generated through in-situ reaction between the sintering aids. The ZrB2 or ZrC-based bulk material prepared by the method has the relative density of over 97 percent, the room temperature bending strength of 500-800MPa, the fracture toughness of 3.5-6.5MPa.ml/2, and the hardness of 14-20GPa. The second phase generated through the in-situ reaction has the same melting point as the matrix, and the sintering acids cannot bring adverse effect to the high temperature mechanical properties of the material.
