Translation of "Reactive metals" in German

The catalytic reactive metals are particularly advantageously used in a finely divided form.

This could provide particular advantages in particular with reactive metals, such as for example aluminum.

Highly reactive metals such as titanium pose particular challenges when casting.

We get ours from Reactive Metals in Arizona.

In particular it is essentially free of reactive metals or metal compounds, in particular free of reactive iron compounds.

This bond is considerably more stable than comparable bonds between carbon and the highly reactive metals lithium or magnesium.

They are designed for applications requiring a special performance, such as primer and topcoats for plastics, primer coat for ferrous substrates, primer coat for reactive metals such as zinc and aluminium, anticorrosion finishes, floor coatings, including for wood and cement floors, graffiti resistance, flame retardant, and hygiene standards in the food or drink industry or health services;

The present inventors experienced that the addition of reactive metals to iron melts, such as for example magnesium, by means of a cored wire, has the disadvantage that, even after ending the insertion process, a considerable and indefinite part of wire continued to burn before it was extinguished.

During this procedure, the metal carbonyls decompose into CO and reactive heavy metals, the latter, in turn, forming metallic sulfides with the H2 S present, whereby obstructions occur at various locations in the apparatus.

Owing to the expansion, the metal carbonyls are decomposed into reactive heavy metals and CO, and the heavy metals then can combine with the hydrogen sulfide present in the methanol to form metal sulfides and elemental hydrogen.

The present invention achieves this goal by providing a method by which reactive metals can be formed into thin sections in a hot working process which can be carried out in an unmodified atmosphere at ambient pressure and which does not require complicated machining or chemical stripping of an encapsulant.

However, atomization is not possible in the case of high-melting or reactive metals or in the case of alloys which demix on melting.

The scale of metals melted and purified in electron beam melting installations extends from the radioactive metals over the nonferrous heavy metals, different steel qualities up to the reactive and refractory metals and their alloys.

When depositing insulating layers by reactive vaporization of metals or by direct vaporization of insulating compounds after a very short time the anode is covered with an insulating coating.

In addition to the basic solder, activated soldering materials additionally include alloying, highly reactive metals, for example titanium (Ti) or zirconium (Zr).

Nilfisk has dedicated solutions for those producing refractory materials, lubricants, pencils, colorings, electrodes and molds for reactive metals, all products manufactured with or containing graphite.

It is considered a precious metal because it is one of the least reactive metals that exists, it is resistant to corrosion, even at the highest of temperatures.

The good chemical stability permits also its use when forming reactive metals such as titanium, which are used in aerospace and defense technology.

An almost always required step in metallothermic reductions for making reactive rare metals is the inertization of the reaction mass prior to, during and after the reduction reaction.

In making very reactive rare metals such as zirconium, titanium and hafnium it is necessary to phlegmatize the metal powders in a targeted way in order to subsequently even be able to handle them exposed to air and to be able to process them further.

The object of the present invention is to provide a method of and a reaction vessel for performing a method of producing metal powders or alloy powders of the reactive metals zirconium, titanium or hafnium from the corresponding oxides or oxide mixtures, whereby the reactive metal powders or alloy powders that are produced are capable of being subsequently handled when exposed to air, for example, for the purpose of further processing.
