CERAMIC FLOW PATH BODY AND HEAT EXCHANGER THEREWITH
PROBLEM TO BE SOLVED: To provide a ceramic flow path body produced by joining a silicon carbide sintered compact to each other, the silicon carbide sintered compacts having excellent durability, corrosion resistance and airtightness, and to provide a heat exchanger with the ceramic flow path body.SOLUTION: A ceramic flow path body comprises a silicon carbide sintered compact in which the first and second members 1 and 2 concurrently having through-holes are joined via a joint layer 3, and continuance of the through-holes is made to be the flow path 4 of a fluid. The flow path body has a first area 5 comprising silicon carbide as a main component and a second area 6 comprising metallic silicon as the main component in the cross section of the joint layer 3 in view of a fluid flow direction. Either one of the first area 5 or the second area 6 positions at the side of the flow path 4, and the other surrounds the former at an outer peripheral side.SELECTED DRAWING: Figure 1
【課題】優れた耐久性、耐食性及び気密性を有する炭化珪素質焼結体同士を接合してなるセラミック流路体及び前記セラミック流路体を備える熱交換器の提供。【解決手段】共に貫通孔を有する第１部材１と第２部材２とが接合層３を介して接合され、貫通孔の連なりが流体の流路４とされた炭化珪素質焼結体からなり、流体の流れる方向に見た接合層３の断面において、炭化珪素を主成分とする第１の領域５と、金属珪素を主成分とする第２の領域６とを有しており、第１の領域５及び第２の領域６のいずれか一方が流路４側に位置しているとともに、他方が外周側で囲繞しているセラミック流路体。【選択図】図１
