摘要

The process for manufacturing a ceramic heat exchanger device having a plate assembly, comprises producing two ceramic plates (1, 2) having a fluid circuit, polishing two sides of the ceramic plates, and applying the polished sides one against the other to obtain an expected sealed assembly. The sides of the plates are polished by grinding the sides using a first polishing fluid, and then polishing using a second fluid. The first and second polishing fluids are provided with an aqueous base and non-aqueous base, and contain diamond powder formed of grains. The process for manufacturing a ceramic heat exchanger device having a plate assembly, comprises producing two ceramic plates (1, 2) having a fluid circuit, polishing two sides of the ceramic plates, and applying the polished sides one against the other to obtain an expected sealed assembly. The sides of the plates are polished by grinding the sides using a first polishing fluid, and then polishing using a second fluid. The first and second polishing fluids are provided with an aqueous base and non-aqueous base, and contain diamond powder formed of grains with a diameter of 50-20 mu m and 10-1 mu m, respectively. The assembly has a lower flatness of 150 nm and a lower roughness of 1 nm RMS. The sides of the plates are grinded on a grind having a rotative ceramic plate or a metal alloy, and are polished on a plane polisher having rotative plate made of metal alloy and organic or textile polymer. A hard design of submicronic ceramic powder is obtained by isostatic pressing. Additives are added to the submicronic ceramic powder to obtain a desired ceramic. A plane sample of the hard design is used for obtaining the ceramic, and sintered at 2100[deg] C in a vacuum oven. Independent claims are included for: (1) a ceramic heat exchanger; (2) a ceramic chemical reactor; and (3) a heat dissipator.
