Production method null of the ceramic connection union which uses the jig and the said jig for ceramic connection union production

摘要

PURPOSE: To prevent the mispositioning of members in sintering by using a jig with specified structure to joint a ceramics perforated plate and a ceramics tubular body. ;CONSTITUTION: A tubular body 2 made of a ceramics sintered body is inserted into each through-hole 3 of the perforated plate 1 made of a ceramics unsitered body having plural through-holes 3, the tubular body 2 is erected vertically to the floor to position the plate 1 at the upper and lower ends of the tubular body 2, and the assembly is sintered and integrally joined by utilizing the difference in shrinkage rate in sintering between both members. In this case, a jig 6 with the following structure is used. Namely, the jig consists of an end part 13 to be inserted into the jig fixing hole 12 preformed in the plate 1 and having an outer diameter slightly smaller than the diameter of the hole 12 and a barrel part 14 having an outer diameter larger than the diameter of the hole 12, the end part 13 and barrel part 14 are separably combined at the engaging part 16 when the end and barrel parts are engaged without being restricted by each other, and the jig is integrated with the ceramics joined body after the joining is completed.;COPYRIGHT: (C)1995,JPO
