A ceramic electronic component (20) having surface conductor films (23) and side-surface conductor films (24) excellent in burning shrinkage, bonding strength, solder heat resistance, solder wettability and the like. A method of producing a ceramic electronic component which uses a conductive paste containing as a main component Ag-based metal powder, the surface of the metal powder being coated with an organic metal compound or a metal oxide having as a constituting element any one selected from a group consisting of Al, Zr, Ti, Y, Ca, Mg and Zn, to form conductor films (23, 24 25) on a ceramic base material (21). A side-surface conductor film-forming paste differs form a surface conductor film-forming paste in that (1) the former paste has a relatively small coating amount of the organic metal compound or metal oxide and/or (2) contains either at least one kind of inorganic oxide powder as an accessory composition or a comparatively high percentage of the inorganic oxide powder.

The invention relates to a multilayer composite metal oxide catalyst. The multilayer composite metal oxide catalyst has the general formula as follows: Mo[a]Bi[b]Ni[c]Cs[d]Cu[e]Ti[f]A[g]B[h]C[i]O[j], wherein Mo is molybdenum, Bi is bismuth, Ni is nickel, Cs is cesium, Cu is copper, and Ti is titanium; A is at least one element selected from arsenic, tellurium, manganese, cerium, niobium, zirconium, rubidium, cadmium and germanium; B is at least one element selected from cobalt, boron, strontium, tantalum, alkali metal and alkaline earth metal; C is at least one element selected from vanadium, stannum, gallium, zinc, ferrum, tungsten and stibium; and O is oxygen. The composite metal oxide catalyst has a multilayer structure in which the concentrations of all the elements are reduced progressively from a matrix at the inner layer to the outer layer. The catalyst provided by the invention can effectively reduce the local heat accumulation of single pipe reactors and inhibit the formation of hot spots, and has the characteristics of high reactivity and selectivity and long service life.

An improved braze alloy is microalloyed to include about 0.0005 wt % to about 0.5 wt % of at least one aggressively surface acting element selected from tellurium (Te), selenium (Se), antimony (Sb), bismuth (Bi), and gallium (Ga), or any combination thereof.

The invention discloses a powder metallurgy rare-earth copper-clad iron alloy oil-impregnated bearing and a manufacturing method thereof. Accounted by percentage, the bearing consists of the following compositions by percentage: 18 to 22 percent of Cu, 0.2 to 1.0 percent of graphite, 0.3 to 0.8 percent of La or Ce and the residual quantity of Fe and unavoidable impurities. The bearing is made by the procedures of mixing, low temperature diffusion treatment, pressing, sintering and the like of a mixture formed by copper-clad iron powder, powder of the element La or Ce and the residual quantity of Fe and unavoidable impurities according to certain mixture ratios. The bearing uses the iron powder for substituting most of the copper powder to reduce the manufacturing cost; lead is not contained in the bearing, which meets the requirement of environmental protection; the rare earth is adopted as a catalyst for causing the copper-clad iron powder to be easily combined with other powder, and the alloy is uniformly distributed, which is beneficial for the refinement of alloy grains and leads thin through holes to be formed in the sintering body with hole connection efficiency being more than 95 percent. The mechanical property of the bearing is better than technical standards of oil-impregnated bearings sintered by copper-clad iron powder and 6-6-3 bronze powder.
