摘要： A method for manufacturing an elastic deformation body made of an Al2O3 ceramic according to which a highly pure alumina having at most 2000 ppm MgO, at most 200 ppm inorganic impurities, a specific surface of at least 10 m2/g, an average grain size of at most 0.3 μm is applied. With the alumina and additives, there is produced via aqueous processing a homogeneous mixture, from which a pressable spray granulate is produced, which is formed by means of a uniaxial pressing method to a homogeneous, green body, which is subjected to a sinter process. The resulting elastic deformation body has a bending fracture stress σc, whose distribution F(σc) is given by the Weibull parameters σ0≧800 MPa and m≧24, with an average grain size of the sintered material of no more than 2 μm, and wherein the sintered material of the deformation body has a density of not less than 3.98 g/cm3.

摘要： This process serves to form a long-time-vacuum-tight, high-strength, and corrosion-resistant joint, by means of a joining material, between a first body and a second body each made of sintered, polycrystalline alumina ceramic with a purity greater than 92 wt. % or of sapphire. The joining material is interposed in the form of a paste, a foil, or a slip between the first body and the second body. The joining material has been made from 1) an agglomerate-free, highly disperse, high-purity .alpha.-alumina powder with particles of as high a degree of calcination as possible and of a size not exceeding 100 nm (=10.sup.-7 m), 2) an anorganic oxidic powder of an auxiliary sintering agent with particles of approximately the same size as the particle size of the .alpha.-alumina powder, 3) an organic vehicle which is dissolved or suspended in an organic or aqueous solvant and in which the particles of the respective powder are distributed as evenly as possible. Instead of the anorganic oxidic powder of an auxiliary sintering agent an anorganic oxidic auxiliary sintering agent produced chemically as envelopes around or attachment to the particles of the .alpha.-alumina powder can be used, the total .alpha.-alumina and auxiliary-sintering-agent content of the paste, the foil, or the slip ranging between 50% and 70%. After interposing the joining material the bodies are heated to a temperature of not more than 1,300.degree. C. and then allowing them to cool down.

摘要： For minimizing the span error of a pressure sensor having an essentially cylindrical platform and a measuring membrane joined to an end face of the platform, wherein the pressure measuring cell is axially clamped between an elastic sealing ring, which bears against the membrane-containing, end face of the pressure measuring cell, and a support ring, which supports the measuring cell on the rear side thereof, the dimensions of the support ring are matched to the dimensions of the sealing ring and the pressure measuring cell in such a way that a radial deformation of the membrane-containing end face resulting from the axial clamping of the pressure measuring cell is sufficiently small that the span error of the pressure sensor because of a reduction of the axial clamping force by a least 10% amounts to not more than 0.02%. The geometry of the support ring is determined iteratively by means of the FEM.

摘要： A ceramic pressure measuring cell with a basic body (1, 3), a diaphragm (5) connected to the basic body (1, 3) to form a measuring chamber (7, 9), which during operation undergoes a deflection dependent on a pressure (p1-p2) to be measured and the deflection of which is registered by means of an electromechanical transducer and is made accessible for further evaluation and/or processing, and a bore (13, 17) which penetrates the basic body (1, 3) and into which a small pressure tube (15, 19) is soldered in a pressure-resistant and gastight manner, and via which a pressure (p1, p2) is introduced into the measuring chamber (7, 9), is provided, in which a volume inside the measuring cell and the small pressure tube is precisely known, since the mechanical stop (33, 35) fixes a depth of penetration of the small pressure tube (15, 19) into the basic body (1, 3).

摘要： This interface connection through a hole (2) in a high-temperature-resistant and vacuum-proof insulating part (1), particularly of ceramic, glass, or a single crystal, consists of a metallic lead (4, 17) inserted into the hole (2) and having a coefficient of thermal expansion less than that of the insulating part (1), wherein at least one end of the lead, if it is flush with at least one surface of the insulating part, is covered with active brazing material which high-vacuum-seals it to the insulating part, or, if it projects beyond at least one surface of the insulating part, is high-vacuum-sealed to the insulating part by means of ring-shaped active brazing material (5'), since in the liquid phase, the active brazing material moves into the gap between the wall of the hole (2) and the lead (4, 17) due to capillary action. Thus, the available materials (insulating material, metals having a smaller coefficient of thermal expansion than the insulating part, active brazing materials) can be used in a different and novel manner such that the use of a lead covered with active brazing material can be dispensed with.
