摘要： This active brazing alloy is preferably used for brazing (joining) (aluminium)oxide ceramic parts or single crystals or metal parts to parts of the same material in each case, or (aluminium) oxide ceramic parts to single crystals or (aluminium) oxide ceramic parts or single crystals to metallic parts. In addition to the zirconium/nickel alloy composed of 70 to 85 atomic % of zirconium and 15 to 30 atomic % of nickel, it contains titanium. In a device for producing a uniformly thick strip (6) of this ternary active brazing alloy which has two surfaces which are as smooth as possible by the melt-spinning method, the alloy which has been melted by means of high-frequency energy in a cylindrical crucible (1) composed completely of a highly heat-resistant and highly thermally conducting, nonmetallic material, in particular of high-density graphite or boron nitride, is squeezed out through an opening (3) in the base of the crucible onto a metal drum (5) which is rotating at high circumferential velocity and has a high thermal conductivity, and the liquid alloy solidifies on the drum at a high cooling rate in the order of magnitude of 10 to 10 DEG C/s. A product produced using said ternary active brazing alloy is a pressure sensor (10) comprising a parent body (12) and a membrane (11) made of ceramic, in particular aluminium oxide ceramic, preferably having a purity of 96% by weight, the parent body (12) and the membrane (11) being thermally joined parallel to one another at their edges and at a known distance (d) by means of the active brazing alloy, for example by means of a shaped part (20) thereof, to form a chamber (13).

摘要： The method for the production of rings (20) of uniform thickness from an active brazing alloy by melt spinning the molten alloy comprises the following steps: the alloy is melted in a crucible (3) with a lateral opening (4), the height (8) of which is approximately equal to the thickness of the material of the rings (20); the molten alloy is forced out of the crucible (3) onto the lateral surface (1') of a metal drum (1) with a high thermal conductivity rotating at high peripheral speed at a distance corresponding approximately to the thickness of the rings, being forced out at a radial distance (r) from the centre (M) of the drum corresponding approximately to the diameter of the rings; after about one quarter to three quarters of a revolution of the active brazing alloy which has solidified on the metal drum (1) to give the ring stock it is lifted off from the metal drum (1) and guided past the crucible (3) by a mechanical deflector (5) or a gas stream (62) blown onto it counter to the direction of rotation of the metal drum (1); the annular spiral (7) formed is guided around a lateral, coaxial extension of the metal drum (1) which serves as a winding mandrel (8), is arranged on the side of the crucible (3) and has an end flange (9) and diameter which is somewhat smaller than the inside diameter of the ring; the rings (20) are then cut off from the annular spiral (7).
