摘要： The invention relates to glass tubes for technical applications, especially for electrical or magnetic components, such as reed switches for example. According to a first embodiment, the glass tube has an inner bore (23) and at least one cross-sectional constriction (X) whereby the relationship applicable between the respective cross-sectional constriction (X) and the diameter (d) of the circumference of inner bore (23) is: x greater than or equal to 0.02*d, more preferably x greater than or equal to 0.1*d. According to a further embodiment, the glass tube has at least one inner bore with at least one inner edge, wherein the radius of curvature of the respective inner edge is less than or equal to 0.1 mm and preferably less than or equal to 0.03 mm. The glass tube is used as a preform for a subsequent redrawing process. The preform is formed by casting a molten glass into a shaft in the interior of which is located a shaping means for defining the inner bore. In this case a gas cushion prevents direct contact of the molten glass with the inner circumferential wall of the shaft and/or the outer circumferential wall of the shaping means.

摘要： A process for producing tubes or rods is provided. The process includes providing a settable liquid and producing a strand by drawing the liquid from a nozzle in a drawing direction. The result of this is that the settable liquid emerges through an annular gap formed by the nozzle with the desired production throughput at the temperature which is above the devitrification temperature. The settable liquid cools as it flows down an outer and/or an inner surface of a displacement body so that, by the end of the displacement body, the settable liquid has a sufficiently high viscosity to be drawn in stable form at the desired production throughout without flowing more quickly than the drawing rate as a result of its own weight.

摘要： In the method of making a monocrystalline or polycrystalline semiconductor material semiconductor raw material is introduced into a melting crucible and directionally solidified using a vertical gradient freeze method. The molten material trickles downward, so that the raw material that has not yet melted gradually slumps in the melting crucible. The semiconductor raw material is replenished from above onto a zone of semiconductor raw material which has not yet melted or is not completely melted to at least partly compensate for shrinkage of the raw material and to raise the filling level. To reduce the melting time and influence the thermal conditions in the system as little as possible, the semiconductor raw material to be replenished is heated to a temperature below its melting temperature and introduced into the crucible in the heated state.

摘要： The invention relates to a method for producing a monocrystalline or polycrystalline semiconductor material by way of directional solidification, wherein lumpy semiconductor raw material is introduced into a melting crucible and melted therein and directionally solidified, in particular using the vertical gradient freeze method.In order to prevent contamination and damage, the semiconductor raw material is melted from the upper end of the melting crucible. The molten material trickles downward, so that semiconductor raw material which has not yet melted gradually slumps in the melting crucible. In this case, the additional semiconductor raw material is replenished to the melting crucible from above onto a zone of semiconductor raw material which has not yet melted or is not completely melted, in order at least partly to compensate for a volumetric shrinkage of the semiconductor raw material and to increase the filling level of the crucible.In order to reduce the melting-on time and to influence the thermal conditions in the system as little as possible, the semiconductor raw material to be replenished is heated by the purposeful introduction of heat to a temperature below the melting temperature of the semiconductor raw material and introduced into the container in the heated state.

摘要： The double crucible for a glass drawing method has a heatable outer crucible (1) and an inner crucible (2) surrounded by the outer crucible (1), which is heatable separately from the outer crucible (1). Both crucibles (1,2) have an outlet nozzle (1a, 2a) for the glass to be drawn. To make glass fibers from heavy metal oxide glass (HMO-glass) with higher quality and comparatively simple crucible features, the outlet nozzle (1a) of the outer crucible (1) extends a certain distance beyond the outlet nozzle (2a) of the inner crucible (2). Surfaces of the outlet nozzles coming in contact with the glass melt are polished and are provided on a material, which has a reducing action on heavy metal glass in the melt in all cases. These surfaces also have sufficient mechanical strength for and chemical inertness to heavy metal oxide glass.
