NOVELTY - The molding contains pores in a single size range or two different size ranges. The pore size within a range, differs by no more than 50 nm. In the single size range, pore sizes lie within the sizes 2-100 nm or 100-300 nm. Where there are two different size ranges, the pore sizes are less than and greater than 200 nm. In this case, the pore sizes range up to 200 nm, and above 300 nm or alternatively up to 200 nm and above 500 nm. Further variant quantified specifications are provided. The pores are partially- or entirely interconnected.    USE - A monolithic metal oxide molding containing submicron pores, which can be used as a vehicle catalyst.    ADVANTAGE - The method produces sintered moldings with pores in controlled, submicron size ranges, using a comparatively-simple manufacturing technique. The product has widely-ranging industrial applications, e.g. as a catalyst in the automobile industry, as battery electrode material with high surface area, in biosensors, in fuel cells, as filtration- or membrane material.    DETAILED DESCRIPTION - The pores are directionally-orientated, with at least some forming a complete pore cavity directed spatially through the molding. The monolithic foam comprises CuO, NiO, TiC, TiO2, ZrO, ZrO2 and/or Al2O3. To make the molding, metal powder and carbon nanotubes or carbon fibers (the carbon forms) are mixed together and ground in the absence of oxygen. Only sufficient of the carbon form is added, to reach a suitable range of pore sizes whilst preventing agglomeration of the carbon. Their dimensions differ by no more than 20 nm. Alternatively, to reach two different size ranges, sufficient of the carbon form is added, to promote partial agglomeration. At most, submicron agglomerates are formed. The mixture is then compacted or compressed under vacuum, followed by temperature treatment in an oxygen-containing atmosphere. The temperature used is below the melting point of the metals and above a temperature at which oxidation of carbon and the metals occurs. The metal powder added is Cu, Ni, Ti, Zr and/or Al at particle sizes exceeding 250 mu m. The nanotubes are single- or multi-walled and unfilled. They are 1-100 nm in diameter and up to 50 nm in length. Mixing and grinding is under inert gas atmosphere and/or vacuum. Mixing and grinding to produce two different pore size ranges, is carried out in two to five stages, within 30 minutes to 400 hours. Up to 20 vol% of the total volume is added in carbon form; or up to 60 vol% when making two different size ranges of pores. Compaction is by equal channel angular pressing (ECAP), high pressure torsion (HPT), hot isostatic pressing (HIP), cold isostatic pressing (CIP) or extrusion at 400-700 degrees C in 10 s to 10 minutes. The temperature treatment is at 400 degrees C - 1000 degrees C for 30 minutes -100 hours. This continues until oxidation of the carbon form and metal is up to 95% complete. AN INDEPENDENT CLAIM IS INCLUDED FOR the method of manufacture.
