摘要： In order to connect a tube of a more common material, such as stainless steel, to a tube of a highly corrosion-resistant metal such as tantalum, where the two tubes cannot be welded together by fussion technology, a connection piece is made of two closely fitting layers of the two materials telescoped into each other, which are exposed to hot compressed noble gas, such as argon, in a pressure vessel, with precautions against oxidation from residual oxygen in the noble gas. Then the ends are machined to remove any hard soldered portion used to make a gas-tight seal of the blank before pressure treatment, after which a longer ring-shaped section of the stainless part of the connection piece is removed at one end and likewise a section of the tantalum part of the connection piece at the other end, so that the projecting ends can be welded to the pipes to be joined. One method of protection against oxidation is to use a blank in which a tantalum tube is fitted between two stainless steel tubes, one of which is completely removed by machining after the pressure treatment.

摘要： Methods for producing a quartz glass component with reflector layer are known in which a reflector layer composed of quartz glass acting as a diffuse reflector is produced on at least part of the surface of a substrate body composed of quartz glass. In order, taking this as a departure point, to specify a method which enables cost-effective and reproducible production of uniform SiO2 reflector layers on quartz glass components, it is proposed according to the invention that the reflector layer is produced by thermal spraying by means of SiO2 particles being fed to an energy carrier, being incipiently melted or melted by means of said energy carrier and being deposited on the substrate body. In the case of a quartz glass component obtained according to the method, the SiO2 reflector layer is formed as a layer which is produced by thermal spraying and has an opaque effect and which is distinguished by freedom from cracks and uniformity.

摘要： Composite material with high resistance to temperature changes and a high density, and having an SiO2-containing matrix with quartz glass grains embedded therein is produced by preparing a suspension from a particle mixture of finely divided SiO2 powder having at least two different particle fractions and of the quartz glass grains, forming a green compact and sintering the compact. The matrix has an SiO2 content of at least 99% by wt. and is formed from at least first and second particle fractions, each of which is present as granules of nanoscale, amorphous, synthetically produced SiO2 primary particles having a mean primary particle size of less than 100 nm. The composite material has an SiO2-containing matrix with an SiO2 content of at least 99% by wt. It is particularly suited for applications such as starting material for producing a permanent mold for melting solar silicon.

摘要： In a known process for the production of opaque quartz glass a blank is formed from synthetic SiO2 granulate and is heated at a vitrification temperature to form a body of opaque quartz glass. In order to provide on this basis a process for the production of pure opaque quartz glass with a homogenous pore distribution, high density, high viscosity and a low tendency to devitrify, it is proposed according to the invention that the SiO2 granulate to be used is a SiO2 granulate (21; 31) composed of at least partially porous agglomerates of SiO2 primary particles, with a specific BET surface ranging from 1.5 m2/g to 40 m2/g and an apparent density of at least 0.8 g/cm3. A SiO2 granulate (21; 31) suitable for the implementation of the process is distinguished in that it is formed from at least partially porous agglomerates of SiO2 primary particles and in that it has a specific BET surface ranging from 1.5 m2/g to 40 m2/g and an apparent density of at least 0.6 g/cm3.

摘要： A bipolar electrode has plate-like anode and cathode parts. The anode and cathode parts are secured together, edge-to-edge, to form a single element in one plane by an intermediate connecting piece. The intermediate connecting piece itself is a composite element having parts of materials which are compatible with the respectively adjacent anode and cathode. The two parts of the composite element are joined together by hot isostatic pressure, explosion-plating or diffusion-welding into the composite body, the resultant composite body then permitting welding of the respective anode and cathode plates to the respective anode part and cathode part of the composite element or body.
