    摘要： A high performance ceramic composite containing tungsten carbide reinforced chromium carbide matrix in which 5.about.35 vol % of tungsten carbide particles are uniformly dispersed in 65.about.95 vol % of chromium carbide matrix. The diameters of the tungsten carbide and chromium carbide particles are preferably in the rage between 0.1.about.10 .mu.m, and their average diameters are preferably at about 2.0 and 1.5 .mu.m, respectively. The tungsten carbide/chromium carbide composite is prepared from a sintering process by applying heat and pressure to a green compact containing tungsten carbide and chromium carbide particles, without using a metallic sintering aid. As a result, the tungsten carbide reinforced chromium carbide composite retains all the advantageous characteristics of the chromium carbide material, such as excellent strength, hardness, anti-oxidation, anti-scaling, anti-erosion and anti-corrosion properties as well as excellent permanent non-magnetizability and surface lustrousness, while providing improved flexural strength and fracture toughness. The tungsten carbide reinforced chromium carbide composite is most suitable for industrial applications where reliability is critical.

    摘要： A composite ceramic block gauge and its preparing method is disclosed. The ceramic block gauge comprises a tungsten carbide (WC) reinforced phase and a chromium carbide (Cr.sub.3 C.sub.2) matrix. The finished block gauge possesses excellent properties such as hardness and corrosion resistance and high reflectivity. The block gauges made from Cr.sub.3 C.sub.2 /WC composites can be calibrated using the traditional optical interferometry techniques.

    摘要： A field emitting luminous device is disclosed. The device includes a cathode electron emitting unit, an electron amplifying unit, a panel unit, and an electric power supply unit. The primary electrons emitted from the cathode electron emitting unit hit the electron amplifying material on the electrode surface of the electron amplifying unit, generating amplified secondary electrons. The secondary electrons bombard the light-emitting layer of the panel unit, producing fluorescence. The fluorescence penetrates the upper transparent panel and is thus observed by eyes.

    摘要： A heat treatment method is disclosed for improving the strength and the toughness of particle reinforced alumina composite. A densified alumina composite is heated to a temperature of higher than 600.degree. C., maintained at that temperature for about 0.5-150 hours, and then the temperature is lowered to room temperature. As a result, the flexure strength and the fracture tougnness of the particle reinforced alumina composite are substantially increased after the heat treatment in comparison to those without heat treatment.
