    Abstract: A plasma display panel is disclosed, which comprises a pair of insulating substrates with a predetermined space therebetween; a group of anode electrodes and a group of cathode electrodes formed on the inner side of each of the insulating substrates in such a manner that the groups of the electrodes are normal to each other; and barriers formed on the insulating substrate having the anode electrodes thereon by photolithography. Since the barriers are formed by photolithography using an ultraviolet-curable resin or positive-type resist, high precison patterns having a line width of 100 .mu.m or less and a line spacing of 100 .mu.m or less can be easily obtained and, thereby, a high resolution plasma display having a decreased picture element area and a wider discharge space can be obtained. When photolithography is used in the formation of the cathode electrodes, further high precision fine patterns can be obtained and further finely detailed pitch of picture elements can be achieved.

C., alumina particles and a glass composition comprising an alumina component. When a total amount of alumina in the substrate is equal to or greater than that in the insulating layer, an amount of Cr.sub.2 O.sub.3 or MnO.sub.2 is restricted to a range between 0.1% and 10.0% by weight, with a difference between the total amounts of alumina falling within a range between 0% and 30% by weight. When the total amount of alumina in the substrate is smaller than that in the insulating layer, the amounts of Cr.sub.2 O.sub.3 and MnO.sub.2 may be between 0.1% and 10.0% by weight and between 0.1% and 15% by weight, respectively. The difference between the total amounts of alumina may be between 0% and 20% by weight.

    Abstract: A dielectric ceramic composition consisting essentially of a BaO-TiO.sub.2 -WO.sub.3 ternary system wherein molar percentages of BaO, TiO.sub.2 and WO.sub.3 are within the range enclosed by a line joining the points of A(21.5, 78.5, 0), B(40.0, 30.0, 30.0), C(37.0, 30.0, 33.0), D(20.0, 75.0, 5.0), E(21.5, 75.0, 3.5) and A of a composition diagram shown in the attached FIGURE, the range excluding molar percentages of BaO, TiO.sub.2 and WO.sub.3 laying on a line joining said points A, E and D. In the dielectric ceramic composition, up to 10 mole % of TiO.sub.2 may be replaced by tetravalent metal oxide and, further, MnO is contained in amounts of 3 mole % or less with respect to 100 mole % of the sum of BaO, TiO.sub.2 and WO.sub.3. Since the dielectric ceramic composition has a beneficial combination of dielectric properties, particularly a high Q, properly small dielectric constant and sufficiently small temperature coefficient of resonant frequency, .tau..sub.f, and .tau..sub.f, can be adjusted to a desired value in the vicinity of 0 ppm/.degree.C., it is especially greatly useful at the microwave range.

    Abstract: Low temperature fired ceramics are produced by a highly improved method, using a specially designed apparatus and the obtained ceramic products are very useful in various applications, such as electronic components, heat resistant articles, tablewares, kitchen utensils or decorative articles because of a combination of superior properties, particularly high heat resistance, high mechanical strength, low thermal expansion and low dielectric constant. In practicing the method, a low firable ceramic material is shaped into a green sheet and then converted to a dense fired ceramic product by rapid firing in an adequate air. In the firing step, the air feed ratio (the ratio of the quantity of feed of air to the theoretical quantity of air required for combustion) is controlled so as to be at least 1.5 thereby the aimed fired products can be obtained in a greatly reduced firing time, without causing deformation or warpage of the ceramics or ignition of the decomposition gases of a binder.
