    Abstract: The invention relates to a method for sintering aluminium-based sintered parts which are, initially, guided with the aid of a transport system T through a de-binding area (3) before being guided through followed by a sintering area (2) and finally being guided through a cooling area (4). Inert gas atmosphere prevails in the sintering area (2), provided with an oxygen content, corresponding to a thawing point of, maximum, 40° C. The sintered parts (23) are heated to the required sintering temperature of 560-620° C., by means of convection, whereby the inert gas atmosphere is accordingly heated, flowing around said sintered parts in a corresponding manner.

    Abstract: A nitrogen containing metal powder with a large specific surface area, and containing a suitable quantity of nitrogen dispersed uniformly within the metal is produced with good productivity, and provides a solid electrolytic capacitor with a high capacitance, minimal leakage current, and excellent long term reliability. This nitrogen containing metal powder has a ratio W/S between the nitrogen content W nullppmnull of the powder, and the specific surface area S nullm2/gnull, as measured by a BET method, that falls within a range from 500 to 3000. This type of powder can be produced by a process in which a metal salt containing the metal is reacted with a reducing agent and undergoes reduction within a diluent salt, thereby generating the metal, wherein a nitrogen containing gas is introduced into the space contacting the reaction melt comprising the metal salt, the reducing agent and the diluent salt, thereby generating the metal and incorporating the nitrogen within the metal.

    Abstract: A non-aqueous electrolyte secondary battery containing an alloy particle capable of absorbing and desorbing lithium in the negative electrode has a short cycle life and is insufficient in high-rate discharge characteristics, since the alloy particle is pulverized during charge/discharge cycles. In order to solve this problem, a negative electrode is employed, which comprises an alloy particle containing: at least two selected from the group consisting of metal elements and semimetal elements; oxygen; and nitrogen. It is preferred that the alloy particle have a phase A capable of electrochemically absorbing and desorbing lithium ion and a phase B having lithium ion conductivity or lithium ion permeability and that the phase B contain larger amounts of oxygen and nitrogen than the phase A.

    Abstract: A method for the manufacture of a three-dimensional object includes the steps of forming a mixture that contains a binder, a wetting agent, and a least one of aluminum or a first aluminum-base alloy into a green composite, removing the binder from said green composite forming a porous preform structure and infiltrating the porous preform structure with a molten second aluminum base alloy to form the three-dimensional object with near theoretical density. The wetting agent assists in wetting during infiltration. The green composite may be formed by an additive process such as computer aided rapid prototyping, for example selective laser sintering. The method facilitates the rapid manufacture of aluminum components by an inexpensive technique that provides high dimensional stability and high density.
