Description
Alliage remplaçant le platine. La présente invention a pour objet un al liage destiné à remplacer le platine dans la plupart de ses applications, en particulier dans les laboratoires chimiques.
Cet alliage est composé de: 75 à 85 % .d'or, 10 à 15 % de palladium, et 2,5 à 10 % de platine.
Il peut être obtenu en fondant ensemble lesdits métaux dans un creuset, le mélange fondu étant ensuite coulé en lingotières et travaillé à froid.
L'alliage ainsi formé possède des pro priétés qui permettent de l'employer clans beaucoup de cas, à la place du platine. Le point de fusion est compris entre 1800 et 1400 suivant la composition centésimale; le métal est complètement inoxydable à l'air, à haute et à basse température.
Un disque .d'un alliage de la composition sus-indiquée, présentant une surface de 13,6 cm', et,mis en contact avec les réactifs pendant une durée de 20 heures à froid, et 15 minutes à chaud (température d'ébulli tion) n'a pas été attaqué avec: l'acide sulfurique à 66 Bé pur, l'acide nitrique à 40 I3é, l'acide chlorhydrique concentré, l'acide acétique glacial, la soude caustique à 10 %, la potasse caustique à 10 %.
La fusion dans un creuset de ce métal a donné, à une température variant de 700 à 1000 pendant 15 minutes, les résultats sui vants: avec le carbonate de soude - pas d'attaque, avec le carbonate de potasse - pas d'attaque, avec le nitrate de potasse - pas d'attaque, avec le nitrate de soude - pas .d'attaque, avec le mélange sodicopotassique - pas d'at taque, avec la soude caustique: une attaque de 0,0035 gr sur 3 gr de soude.
L'or étant beaucoup moins cher que le platine et le palladium, et entrant pour la plus grande partie dans la composition, l'al liage sera évidemment d'un prix beaucoup inférieur à celui du platine pur (environ le tiers), tout en ayant la plupart .des qualités caractéristiques de ce métal précieux. Il est à noter qu'en dehors des limites de propor- ions mentionnées, les propriétés s'altèrent (.u l'alliage devient d'un prix prohibitif.
Alloy replacing platinum. The present invention relates to an alloy intended to replace platinum in most of its applications, in particular in chemical laboratories.
This alloy is composed of: 75 to 85% gold, 10 to 15% palladium, and 2.5 to 10% platinum.
It can be obtained by melting said metals together in a crucible, the molten mixture then being poured into ingots and cold worked.
The alloy thus formed has properties which make it possible to use it in many cases, in place of platinum. The melting point is between 1800 and 1400 depending on the percentage composition; the metal is completely stainless in air, at high and low temperature.
A disc. Of an alloy of the above-mentioned composition, having a surface area of 13.6 cm ', and, brought into contact with the reagents for a period of 20 hours in the cold, and 15 minutes in the hot (temperature of boiling) has not been attacked with: pure sulfuric acid 66 Bé, nitric acid 40 I3, concentrated hydrochloric acid, glacial acetic acid, 10% caustic soda, caustic potash at 10%.
The fusion in a crucible of this metal gave, at a temperature varying from 700 to 1000 for 15 minutes, the following results: with soda ash - no attack, with potassium carbonate - no attack, with potassium nitrate - no attack, with sodium nitrate - no attack, with the sodium and potassium mixture - no attack, with caustic soda: an attack of 0.0035 gr on 3 gr of welded.
Gold being much less expensive than platinum and palladium, and entering for the most part in the composition, the alloy will obviously be of a much lower price than that of pure platinum (about a third), while having most of the characteristic qualities of this precious metal. It should be noted that outside the limits of the proportions mentioned, the properties deteriorate (the alloy becomes prohibitively expensive.
